Abstract
Effective chiller sanitation is critical in poultry processing to minimize microbial contamination, preserve product quality, and maintain equipment integrity. This study evaluated the comparative performance of Intra Hydrocare, a chelated silver-stabilized hydrogen peroxide formulation, and sodium hypochlorite (NaOCl) at 50 ppm in screw chillers of a commercial poultry processing plant in Punjab, India. Over a two-month field trial, weekly samples (n = 12/event) were collected from chiller inlet water, outlet water, surfaces, and carcass rinses. Microbial load was assessed using Total Plate Count (TPC) and ATP bioluminescence, while equipment hygiene, sensory quality, and operator safety were also evaluated. Intra Hydrocare demonstrated consistently superior antimicrobial performance, maintaining >99.9% microbial reduction throughout the chilling cycle, compared with the rapid efficacy decay observed with NaOCl (≈50% loss by outlet). Biofilm disruption was markedly improved with Intra Hydrocare, reflected by an 85% reduction in ATP values. Chillers treated with NaOCl showed scaling and surface dulling, whereas Intra Hydrocare prevented corrosion, removed existing deposits, and supported improved hygiene. Sensory evaluation confirmed that Intra Hydrocare preserved product colour, odour, and texture, while NaOCl occasionally produced chlorinous odours and bleaching. Operator observations also indicated reduced eye irritation and improved handling safety with Intra Hydrocare. These findings highlight Intra Hydrocare as a highly effective, residue-free, and sustainable alternative to hypochlorite-based disinfectants in poultry screw chillers. Its adoption can enhance food safety, extend equipment lifespan, support certification compliance, and elevate overall processing efficiency.

Introduction
Effective sanitation in poultry processing plants is essential to minimize microbial contamination and ensure the safety and quality of final products. Screw chillers, which are critical for rapidly reducing carcass temperature following evisceration, represent a high-risk point for cross-contamination due to continuous exposure to organic matter, water recirculation, and contact between carcasses (Buncic & Sofos, 2012). Pathogens such as Salmonella spp. and Campylobacter spp. are frequently introduced into chiller systems and can persist on equipment surfaces or within biofilms, posing a significant public health risk and contributing to foodborne illnesses globally (EFSA, 2024; Scallan et al., 2011).

Sodium hypochlorite (NaOCl) remains one of the most widely used disinfectants in poultry chillers due to its broad-spectrum antimicrobial activity and low cost (Kim et al., 2023). In commercial processing, NaOCl is typically applied at concentrations around 50 ppm (Na et al., 2023) However, its performance is constrained by several operational and chemical limitations. First, chlorine activity is highly pH-dependent, with optimal performance in acidic environments (pH <7), whereas chiller systems often operate under neutral to slightly alkaline conditions, reducing biocidal efficacy (Amiri et al, 2010). Second, NaOCl reacts rapidly with organic matter, such as blood, fat, and proteins, leading to immediate depletion of free available chlorine and requiring repeated dosing to maintain effective concentrations (Waters and Hung, 2014). Third, sodium hypochlorite shows limited penetration into complex biofilms, which enables survival of Campylobacter, Listeria, and Salmonella on chiller surfaces despite routine sanitation (Alvarez-Ordóñez et al., 2019). Lastly, excessive dosing used to compensate for chlorine loss can negatively affect product quality, producing chlorinous off-odours, yellow discoloration, and bitterness, contributing to rejection rates of 15–20% in high-throughput processing plants (Agnello et al.,2012; Hurlbut et al.,1983; Gretchen Marlene Nagel, 2012; Kumar et al.,2023)

These limitations have prompted interest in alternative biocides that can maintain stability in organic-rich environments, exert broad antimicrobial action, avoid product quality deterioration, and improve worker safety. Intra Hydrocare, an ultra-stabilized hydrogen peroxide formulation, has gained recognition as a next-generation disinfectant. It is approved by the European Chemicals Agency (ECHA) under the Biocidal Products Regulation (BPR) for PT02, PT03, PT04, and PT05 applications, and holds NSF/ANSI Standard 60 certification for potable water systems. As a residue-free oxidizing biocide that decomposes into water and oxygen, Intra Hydrocare offers advantages including non-corrosiveness, extended shelf life, and suitability for organic production systems (USDA NOP; EU Organic Regulation 2018/848). Hydrogen peroxide-based disinfectants have demonstrated superior biofilm degradation, greater stability in organic environments, and reduced risk of sensory changes in treated poultry products (Stearns et al., 2022).

Given these properties, Intra Hydrocare presents a promising alternative to NaOCl in poultry chillers. The present study compares the performance of Intra Hydrocare and NaOCl under commercial processing conditions, with an emphasis on microbial reduction (total plate count, TPC), equipment hygiene, operator safety, and downstream product quality outcomes. The findings aim to inform evidence-based selection of sanitizing agents for modern poultry processing systems.

Materials and Methods
Study Period and Setting: The study was conducted from September 2025 to November 2025 at Perfect Poultry Products Pvt. Ltd., Amritsar, Punjab, India, a mid-scale commercial poultry processing plant (CPP) with a capacity of 30,000 birds/day. The facility operates four stainless-steel screw chillers of two sizes (2.1 m × 6 m and 1.6 m × 6 m), with capacities of 12,000 L and 8,500 L, respectively (Figure 1).
Study Design: A controlled, comparative field trial was implemented over a 2-month period. The four screw chillers were divided into two treatment groups:

1. Control group: Sodium Hypochlorite (NaOCl)
a) Two screw chillers operated using 50 ppm sodium hypochlorite (from commercial 10% NaOCl solution).
b) Dosing was performed via inline injection calibrated to maintain consistent free chlorine levels.
c) Water pH was monitored at each sampling (target: 7.2–7.5).
d) Free available chlorine was measured using chlorine indicator strips.

2. Trial group: Intra Hydrocare
a) Two screw chillers operated with 50 ppm Intra Hydrocare (ultra-stabilized hydrogen peroxide formulation).
b) The solution was dosed using a Dosatron venturi injector (dilution ratio 1:256) to ensure precise flow-proportional dosing.
c) Hydrogen peroxide concentration in the chiller water was verified using validated H2O2 test strips.
All chillers operated under identical process conditions. Carcasses underwent post-evisceration chilling for 55 minutes at 4°C (corrected from the earlier 45-minute estimate).

Sampling strategy: Sampling was performed weekly, generating 12 sampling events per chiller group over the study period. Samples were collected from:
a) Chiller inlet water
b) Chiller outlet water
c) Chiller surfaces (food-contact and non-contact)
d) Carcasses (post-chill rinse samples)
All sampling followed ISO/HACCP-aligned aseptic procedures.

Microbiological and Hygiene Assessments
1. Total Plate Count (TPC)
a) Swab samples from chiller surfaces and water were plated on Plate Count Agar (PCA).
b) Incubation: 30°C for 48 hours.
c) Carcass microbial loads were enumerated using the ISO 4833 standard rinse-and-plate method.

Figure 1: Representative pictures of the sampling sites
2. Biofilm assessment: Biofilm presence and surface hygiene were evaluated using ATP bioluminescence (Merck MVP ICON system), reported as relative light units (RLU). High RLU values indicated persistent organic load or biofilm activity.

Product Quality and Sensory Evaluation
1. Sensory attributes: A trained internal panel evaluated carcasses for colour, odour and taste, surface appearance. NaOCl-related off-odours, chlorinous notes, or bleaching were noted when present.
2. Chemical residue assessment: Chicken samples were screened for detectable oxidant residues at the end of the chilling process to compare:
– Chlorine residuals (NaOCl group)
– H2O2 residual absence (expected for Intra Hydrocare, decomposing into water + oxygen)
Operator safety assessment: Observations were recorded regarding operator comfort, PPE compliance, and chemical exposure effects.
– NaOCl exposure frequently caused eye irritation, bleaching of clothing, and harsh odour.
– Intra Hydrocare demonstrated no irritation, no corrosive effects, and better operator acceptability, although standard PPE was maintained as per plant protocols.
Compliance and ethical considerations: All activities adhered to established HACCP, Good Manufacturing Practices (GMP), and routine plant safety protocols. No pathogen-specific testing (e.g., Salmonella, Campylobacter) was undertaken as the focus was on indicator microbial load, hygiene markers, and operational performance.

Results
The comparative evaluation demonstrated that Intra Hydrocare consistently outperformed sodium hypochlorite (NaOCl) across all assessed parameters, including microbial reduction, biofilm control, product quality preservation, and equipment hygiene. A summary of the major findings is presented below.

1. Microbial efficacy
Intra Hydrocare showed substantially superior microbial control in both chiller water and carcass rinses. While NaOCl produced an initial drop in microbial load, its efficacy diminished rapidly as water moved through the chiller system, with approximately 50% loss in free chlorine activity by the outlet point. This decline corresponded with higher Total Plate Count (TPC) values at the outlet.

In contrast, Intra Hydrocare maintained stable activity throughout the chilling cycle, resulting in >99.9% overall log reduction across sampling points. ATP bioluminescence measurements further confirmed enhanced sanitation performance, with an 85% reduction in ATP, indicating strong biofilm disruption.

Table 1. Total Plate Count (TPC) in screw chillers

Notes: TPC expressed as CFU/mL for water and CFU/g for carcass rinses. n = 12 sampling events per treatment group.
These results indicate that Intra Hydrocare provided 2–3-fold lower microbial contamination compared with NaOCl, both at the dressed-bird stage and in final goods (FG), demonstrating sustained antimicrobial activity even under high organic load.

2. Biofilm control, scale reduction, and equipment integrity
Significant differences were observed in chiller hygiene and equipment condition:
a) Biofilm disruption: Intra Hydrocare effectively penetrated and destabilized biofilm layers, reflected in markedly lower ATP values.
b) Surface hygiene: Surfaces treated with Intra Hydrocare remained visibly cleaner, with less organic residue accumulation.
c) Scale formation: NaOCl-treated chillers exhibited noticeable scaling, mineral deposits, and structural dulling, which can entrap microorganisms and reduce sanitation efficiency.
d) Equipment protection: Intra Hydrocare’s non-corrosive nature prevented metal surface degradation and eliminated scaling, reducing the need for frequent maintenance.
Overall, Intra Hydrocare improved operational efficiency, minimized downtime related to cleaning, and contributed to extending equipment service life.

Discussion
The findings of this field trial demonstrate that Intra Hydrocare provides superior sanitation performance compared with sodium hypochlorite (NaOCl) in poultry screw chillers. The stabilized hydrogen peroxide formulation used in Intra Hydrocare, i.e., chelated and silver-stabilized, exhibits several mechanistic advantages that directly contribute to its enhanced performance. Its oxidative mode of action functions effectively across a broad pH range (pH 3–8), providing greater stability in the slightly alkaline conditions common in poultry chillers. This contrasts with NaOCl, whose antimicrobial efficacy diminishes rapidly outside acidic-to-neutral pH ranges and is highly susceptible to neutralization by organic matter present in post-evisceration water.

The trial results demonstrated that Intra Hydrocare maintained >99.9% microbial reduction throughout the chilling cycle, while NaOCl showed a steep decline in performance, losing nearly half of its free chlorine activity before reaching the outlet point. This decline directly corresponded with higher Total Plate Count (TPC) values and diminished sanitation consistency. The enhanced biofilm disruption observed with Intra Hydrocare, reflected by an 85% reduction in ATP values, further underscores its efficacy. Biofilms are notorious for harbouring Salmonella, Campylobacter, Listeria, and spoilage organisms; therefore, effective biofilm control is essential for maintaining plant hygiene and reducing persistent contamination.

A notable advantage of Intra Hydrocare lies in its silver-chelated stabilization, which creates oxidative synergy and promotes deeper penetration into biofilm matrices. This capability addresses a critical weakness of NaOCl, which often requires dose escalation (to 100–150 ppm) in real-world settings to overcome organic load and biofilm protection. However, elevated NaOCl dosing frequently causes adverse sensory changes in poultry meat, including chlorinous odours, yellow discoloration, and surface bleaching, leading to quality downgrades or batch rejections. In contrast, Intra Hydrocare delivered robust disinfection at a low, constant 50 ppm, with no detectable impact on odour, taste, colour, or texture.

From an operational perspective, Intra Hydrocare provided significant additional benefits. Its non-corrosive chemistry prevented structural degradation of stainless-steel surfaces, eliminated scale accumulation, and even removed pre-existing mineral deposits. NaOCl, conversely, contributed to scaling and surface dulling, increasing equipment maintenance burdens. These hygiene and equipment advantages align with sustainability and quality certification goals, including organic production standards (USDA NOP, EU Organic) and NSF/ANSI 60 compliance.

Operator safety was another area where Intra Hydrocare exhibited clear superiority. NaOCl exposure is well-documented to cause eye irritation, respiratory discomfort, and bleaching of clothing, all of which were reported by plant operators. Intra Hydrocare, being residue-free and odourless, eliminated these hazards while still requiring standard PPE under HACCP protocols.

Collectively, the trial outcomes highlight several tangible plant-level benefits associated with switching to Intra Hydrocare, including, lower microbial contamination pressure, improved biofilm and scale control, enhanced product sensory quality and shelf-life potential, reduced equipment corrosion and maintenance downtime, safer working conditions for operators and alignment with modern sustainability and certification frameworks.

The primary limitations of this study include the higher initial dosing volume required for Intra Hydrocare (although mitigated by dosing efficiency and longer-lasting activity) and the need for broader multi-site validation to confirm scalability across different processing environments. Additionally, pathogen-specific analyses, such as Salmonella or Campylobacter enumeration, were not conducted in this phase, although the substantial reductions in indicator organisms and ATP strongly suggest improvements in overall contamination control.

Conclusion
This investigation affirms Intra Hydrocare as a transformative sanitizing agent for poultry screw chiller operations, delivering superior performance across all critical sanitation dimensions. By consistently outperforming NaOCl in microbial reduction, biofilm disruption, equipment hygiene, and sensory preservation, Intra Hydrocare enhances both food safety and product quality throughout the poultry value chain. Its non-corrosive, residue-free, and operator-safe characteristics position Intra Hydrocare as an ideal disinfectant for modern, certification-driven poultry processing plants. The observed improvements, ranging from lower microbial loads to better shelf-life potential, translate directly into enhanced customer satisfaction and stronger market competitiveness.

Adopting Intra Hydrocare represents a strategic shift toward resilient, sustainable, and high-performance sanitation systems, advancing the dual goals of operational efficiency and public health protection. By embracing such next-generation biocidal technologies, poultry processors can ensure safer workplaces, superior consumer experiences, and a robust compliance posture in increasingly demanding regulatory and retail environments.

Abstract
The environment within poultry houses plays a decisive role in the overall health, performance, and welfare of birds. Among various factors, the concentration of ammonia (NH₃) and the level of relative humidity (RH) are the most critical. Ammonia, released from the microbial breakdown of waste, and excessive humidity, which influences litter moisture, often work together to create poor air quality. This review highlights how these two factors are produced, their combined impact on broilers and layers, and outlines practical approaches for monitoring and management to maintain profitability and bird well-being.

1. Introduction
For poultry farmers, achieving optimal productivity requires not just good feed and genetics, but also maintaining a favorable environment inside the house. Air quality, ventilation, and litter condition all directly affect flock health. Ammonia gas and humidity levels are particularly important, as they can significantly influence bird growth, egg production, immune strength, and overall welfare. Excessive ammonia harms the respiratory tract, reduces feed intake, and lowers growth efficiency, while uncontrolled humidity leads to wet litter, higher ammonia emissions, and disease outbreaks. To ensure healthy flocks, ammonia should ideally be kept below 20–25 ppm and RH within 50–70%.

2. How Ammonia and Humidity Build Up
2.1 Generation of Ammonia
Ammonia is created naturally when uric acid in droppings is decomposed by bacteria. The process is intensified under warm, moist, and alkaline conditions. The type of litter material, stocking density, feed composition (especially protein levels), and frequency of manure removal all influence ammonia levels. Houses with poor cleaning routines or high moisture accumulation often experience higher NH₃ concentrations.

2.2 Role of Humidity
Humidity directly controls litter moisture content. High RH slows the evaporation of water from bedding, resulting in wet litter that promotes microbial activity and ammonia release. Conversely, very low RH increases dust particles in the air, which irritates the birds’ airways. Thus, moisture management is closely tied to controlling ammonia levels.

3. Impacts on Bird Health and Physiology
3.1 Respiratory Effects
Ammonia acts as a strong irritant to the respiratory tract. Continuous exposure damages the trachea and air sacs, reducing the ability of cilia to filter pathogens. Birds exposed to more than 20–25 ppm are more prone to respiratory diseases such as Newcastle, bronchitis, and Mycoplasma infections. Vaccination responses also tend to decline.

3.2 Eye and Skin Irritation
Chronic exposure to ammonia causes conjunctivitis, watery eyes, and corneal damage. High RH contributes to wet litter that leads to footpad dermatitis, hock burns, and breast blisters—all of which compromise welfare and reduce carcass quality at processing.

3.3 Growth and Feed Efficiency
High levels of ammonia reduce appetite, slow weight gain, and impair feed conversion. Even a small increase in feed conversion ratio (FCR) significantly raises production costs, especially in large flocks. Performance losses become severe when ammonia concentrations exceed 50 ppm for prolonged periods.

3.4 Immunity
Birds raised in poor air quality often show weaker immune responses. Prolonged exposure to ammonia not only stresses birds but also reduces antibody production after vaccination, leaving them vulnerable to disease outbreaks.

3.5 Egg Production
In layer flocks, poor litter conditions and elevated ammonia cause stress, leading to reduced laying rates, smaller egg size, and poor shell quality. Mortality may also rise due to an increased risk of secondary infections.

4. The Combined Impact of Ammonia and Humidity
Although ammonia and humidity can each harm poultry, their combination is especially damaging. High RH makes litter wetter, which in turn boosts ammonia emissions. Humid air also traps ammonia at bird level, ensuring birds inhale more of it. Together, these conditions encourage respiratory infections, coccidiosis outbreaks, poor weight gain, higher mortality, and overall production losses.

5. Monitoring Levels
5.1 Threshold Values
Ammonia: Should remain below 20–25 ppm (ideally closer to 10 ppm). Birds show signs of irritation even at levels humans may not detect by smell.

Relative Humidity: Best maintained between 50–70%. RH above 75% promotes wet litter, while RH below 40% leads to dust and dehydration.

5.2 Measurement Tools
Ammonia: Can be monitored using portable gas detectors, color tubes, or continuous electronic sensors.
Humidity: Inexpensive hygrometers placed at bird height provide reliable readings and are often integrated into automatic ventilation systems.

6. Strategies for Control
6.1 Ventilation
Proper ventilation ensures air exchange, dilutes gases, and removes excess moisture.

In cold weather: minimum ventilation prevents humidity build-up without chilling the birds. fans and circulation systems increase air movement and reduce heat stress.

6.2 Litter Management
Maintaining dry litter is essential. Turning litter, replacing wet spots, using absorbent bedding materials, and preventing drinker leaks are key practices. Chemical litter amendments such as alum or sodium bisulfate can reduce pH, minimizing ammonia release.

6.3 Nutrition
Adjusting feed formulations to match amino acid requirements reduces nitrogen excretion. Enzyme supplements and probiotics may also improve digestion and reduce ammonia in manure.

6.4 Housing Design
Well-insulated poultry houses with good drainage and properly installed nipple drinkers minimize litter moisture. Preventing condensation on walls and ceilings also helps keep humidity under control.

6.5 Advanced Methods
Technologies like air scrubbers, biofilters, or controlled ozone applications are being tested for large commercial units. Automated environmental control systems that integrate NH₃ and RH sensors with fans and heaters are becoming increasingly popular.

7. Economic Importance
Poor air quality silently eats into farm profits. Lower feed efficiency, reduced weight gain, carcass downgrades, increased mortality, and higher veterinary costs all add up to significant economic losses. Studies show that ammonia-related performance drops can cost large poultry complexes thousands of dollars weekly. Investing in better litter management, ventilation, and nutritional adjustments often proves cost-effective in the long run.

8. Evidence and Case Studies
Field surveys often reveal ammonia exceeding safe levels during winter when ventilation is minimized, leading to higher respiratory issues and welfare concerns. Controlled trials consistently show that birds exposed to even moderate ammonia (20–30 ppm) suffer from lower growth rates, poorer immune response, and more lesions compared to those raised under optimal conditions. Interventions such as litter acidifiers, improved diet formulations, and enhanced ventilation schedules have been shown to significantly reduce ammonia emissions and improve performance.

9. Recommendations for Farmers
– Check RH daily: maintain between 50–70%.
– Monitor ammonia regularly: aim for <20 ppm.
– Fix water leaks immediately to avoid wet litter.
– Adjust ventilation by season to balance temperature, RH, and air quality.
– Work with a nutritionist to optimize protein levels in diets.
– Use litter amendments wisely to reduce ammonia emissions.

10. Future Outlook
The integration of smart sensors and artificial intelligence into poultry housing systems may soon allow farmers to predict ammonia build-up and adjust ventilation automatically. Further research is needed to quantify the long-term welfare and production benefits of advanced technologies and to make them affordable for small- and medium-scale farmers.

11. Conclusion
Ammonia and humidity are closely linked environmental challenges in poultry houses. Both negatively affect bird health, welfare, and productivity when not controlled. Together, they magnify each other’s harmful effects, resulting in economic losses and compromised flock performance. Regular monitoring, proactive litter and ventilation management, balanced nutrition, and modern environmental control tools are essential for maintaining a healthy environment. Addressing these issues not only supports profitability but also improves animal welfare, ensuring sustainable poultry production.

In today’s poultry industry, two factors play a decisive role in ensuring profitable, sustainable, and disease-free production:

Water Treatment and Biosecurity.
Together, they safeguard flock health, enhance performance, and reduce dependence on antibiotics.

1. Water Treatment in Poultry
Water is often called the “forgotten nutrient,” yet it is the most critical element in poultry production. Birds consume twice as much water as feed, and any compromise in water quality directly impacts growth, egg production, and immunity.

Key Challenges in Water Quality
– Microbial contamination: Bacteria such as E. coli and Salmonella spread through untreated water.
– Biofilm formation: Organic residues in pipelines harbor pathogens.
– Chemical impurities: High TDS, hardness, iron, or nitrates affect digestion and performance.
– pH imbalance: Acidic or alkaline water reduces feed intake. Water Treatment Practices
– Filtration to remove physical impurities.
– Acidification to maintain pH (5.5–6.5) and inhibit bacterial growth.
– Chlorination / Hydrogen Peroxide / Ozone for disinfection.
– Regular waterline flushing to prevent biofilm buildup.
– Monitoring TDS, hardness, and microbial load routinely.

2. Biosecurity in Poultry
Biosecurity means preventing disease entry and spread on the farm. With rising concerns about Antimicrobial Resistance (AMR) and the push toward antibiotic-free production, biosecurity has become more important than ever.

Three Levels of Biosecurity
1. Conceptual Biosecurity – Farm location, distance from other poultry units, controlled entry points.
2. Structural Biosecurity – Physical barriers, fencing, bird-proof sheds, water sanitation system.
3. Operational Biosecurity – Day-to-day practices like disinfection, vaccination, and visitor control.

Practical Biosecurity Measures
– Restrict farm access (only authorized persons allowed).
– Provide footbaths, hand sanitizers, and farm clothing.
– Disinfect vehicles, crates, and equipment before entry.
– Implement rodent and wild bird control programs.
– Maintain strict mortality disposal methods (incineration/composting).
– Regular vaccination and health monitoring.
– Keep detailed farm records for traceability.

3. Water Treatment + Biosecurity = Sustainable Poultry
While water treatment ensures internal health and performance, biosecurity provides external protection from infections. Both are complementary and essential.
– Clean water reduces gut-related diseases like colibacillosis and diarrhoea.
– Biosecurity reduces the risk of respiratory and viral infections.
– Together, they help in antibiotic-free poultry production, improve FCR (Feed Conversion Ratio), enhance bird welfare, and boost farmer profitability.

Water Quality Monitoring & Water-Borne Diseases in Poultry

Diagram shows that, the source of water we need to check, Ph, TDS, COLOUR, BACTERIA & VIRAL LOAD. This water will go to overhead tank & from there it will distribute to different Poultry shed tanks & through pipe & nipple it will available for birds, here we need to monitor the quality of water.

Importance of Water Sanitation in Poultry Production
In modern poultry production, the use of feed additives such as water and feed acidifiers, toxin binders, probiotics, and antibiotic growth promoters (AGPs) is a common recommendation by poultry nutritionists. Farmers are also increasingly incorporating low-cost protein sources like Rice DDGS, Maize DDGS, and Meat Meal (sometimes adulterated with leather powder) to reduce feed costs.

However, ignoring water sanitation remains one of the most critical mistakes in poultry farming. Even with balanced feed formulation and additives, if the water provided to the birds is contaminated, it results in:
• Loose droppings due to microbial contamination.
• Poor nutrient absorption – birds fail to utilize protein, energy, minerals, and vitamins in the diet.
• Increased incidence of diseases such as E. coli infections and Salpingitis.
• Weakened immunity and consequently poor production performance.

In contrast, a farm with proper water sanitation shows remarkable differences. For example, in one of my ideally managed farms, the birds consistently showed dry droppings (“DRY BEAT”), a clear indicator of good gut health and proper nutrient absorption. This success was achieved through:
• Regular water sanitation practices (disinfection, acidification, and monitoring).
• Ensuring feed hygiene along with the use of safe, food-grade raw materials.
• Strict biosecurity and management protocols.

Safe Water Treatment – A Farmer’s Responsibility

Many farmers currently use different chemicals such as chlorine gas, bleaching powder, and sodium hypochlorite for water treatment. They are not safe for poultry or humans. These compounds often leave harmful residues, alter water taste, reduce consumption, and may even add toxic by-products into the water. According to WHO guidelines, only food and pharmaceutical grade salt should be used for drinking water treatment — both for humans and poultry. The safest and globally recommended option is NaDCC (Sodium Dichloroisocyanurate), which ensures:
• Broad spectrum disinfection with very effective bacterial control
• Safe for poultry & human consumption
• No significant change in taste or odour
• Eco-friendly & easy handling
• Stable and longer shelf life compared to other chlorine sources

Using sub-standard chemicals not only compromises poultry performance (loose droppings, poor nutrient absorption, higher
disease load, chlorine toxicity) but also risks human food safety through residues in meat and eggs.
Key Impact: Farmers must understand that safe water treatment is not about the cheapest chemical, but about using WHO- recommended, food & pharma grade NaDCC for long-term health, productivity, and profitability.

Note: Why NaDCC (Food & Pharma Grade) is Always Better.

Among all the available chlorine-base compounds for water sanitation, Food & Pharma grade Sodium Dichloroisocyanurate (NaDCC) is the safest and most effective choice.

• WHO Recommended – Approved for safe drinking water treatment globally.
• Broad Spectrum Effectiveness – Provides strong and stable disinfection (48 hours’ stability).
• Safe for Birds & Humans – No harmful residues, no significant change in taste or odor.
• Eco-Friendly – No toxic by-products or sludge formation.
• Long Shelf Life – Up to 3 years, with easy effervescent tablet formulation.
• Ease of Use – Simple handling, no heavy cylinders or high manpower required.
• Therefore, NaDCC (Food & Pharma Grade) is always better than chlorine gas, bleaching powder, sodium hypochlorite, or halozone for ensuring Zero-Bacteria Water in poultry Farms.

Conclusion
In poultry management, prevention is always better than cure. Poultry farming success is not just about what we feed the birds, but also about the quality of water they drink every single day. Feed can be fortified, sheds can be modernized, but without clean water and strict sanitation, the full genetic potential of the flock can never be realized. Water is the simplest yet most powerful tool to secure healthy birds, higher productivity, and long-term profitability. Water treatment and biosecurity are not costs but investments that return multiple benefits in productivity, profitability, and sustainability.

Breathing Trouble: A Glimpse into the World of CRD in Poultry
India ranks second globally in egg production and fifth in poultry meat production. The Indian poultry market, despite being one of the largest globally, remains a developing sector due to its fragmented infrastructure, inconsistent biosecurity standards, and varying degrees of modernization across regions.

A significant portion of poultry production still relies on open housing systems, limited automation, and minimal veterinary oversight, especially among smallholder and backyard farmers. These conditions foster high disease prevalence, as poor sanitation, overcrowding, and lack of structured vaccination programs create ideal environments for the spread of infectious agents like Mycoplasma gallisepticum, E. coli, and coccidia. Consequently, the industry faces substantial economic losses through reduced productivity, higher mortality, increased medication costs, and trade restrictions. Bridging the gap between traditional practices and scientific poultry management is critical for improving flock health and sustaining long-term growth.

One Breath at a Time: Poultry Farmers Battle Chronic Respiratory Disease

Before any effective fight against Chronic Respiratory Disease (CRD) can begin, the poultry industry must first understand the enemy it faces. CRD is not just another seasonal illness—it’s a complex, persistent infection primarily caused by Mycoplasma gallisepticum, capable of silently spreading through flocks and leaving devastating economic consequences in its wake. Its symptoms often mimic those of other respiratory illnesses, making early detection a challenge. Without a clear understanding of its pathogenesis, transmission, and triggers, efforts to control CRD remain reactive and insufficient. Knowledge is the first line of defense—only with education, diagnosis, and structured prevention can farmers hope to break the cycle of recurring outbreaks. The battle against CRD must begin with awareness and be fought with science, vigilance, and unity across the industry.

Unmasking the Culprit: The Hidden Cause of CRD in Poultry

CRD is caused by Mycoplasma gallisepticum (MG), a wall-less bacterium that affects the respiratory tract of poultry. Secondary infections with Escherichia coli, Ornithobacterium rhinotracheale, and viral pathogens (NDV, IBV) often exacerbate disease severity.

Silent Spread: How CRD Continues to Lurk in Poultry Farms
CRD in poultry, caused by Mycoplasma gallisepticum, spreads through both horizontal and vertical transmission. Infected birds release the pathogen via respiratory secretions, contaminating air, water, feed, and equipment. Vertical transmission from breeder hens to chicks via eggs further fuels early infection. Recovered birds often remain silent carriers, shedding the organism under stress. This makes CRD hard to eradicate and highlights the need for strong biosecurity, breeder screening, and flock management to control its spread.

How CRD Takes Hold: Understanding the Disease’s Journey in Poultry
The pathogenesis of Chronic Respiratory Disease (CRD) in poultry begins when birds inhale aerosolized Mycoplasma gallisepticum, the primary causative agent. The pathogen adheres to the ciliated epithelial cells lining the upper respiratory tract, disrupting the mucociliary clearance mechanism. This allows the bacteria to colonize and multiply, triggering a chronic inflammatory response that leads to thick mucus secretion, tracheitis, and air-sacculitis. The damaged respiratory lining also becomes highly susceptible to secondary bacterial infections, particularly from E. coli, compounding respiratory distress and systemic illness.

In commercial poultry, stress factors such as poor ventilation, high stocking density, and concurrent viral infections (like IBV or NDV) can further exacerbate disease progression, resulting in reduced growth rates, poor feed conversion, decreased egg production, and increased mortality.

Signs & Symptoms with Postmortem (PM) Findings
CRD in poultry typically presents with a range of respiratory signs that can vary in severity based on age, immune status, and presence of co-infections. Common clinical signs include coughing, sneezing, nasal discharge, tracheal rales, conjunctivitis, reduced feed intake, stunted growth, and a noticeable drop in egg production in layers. Birds may also exhibit open-mouth breathing and watery eyes. In chronic stages, swelling of infraorbital sinuses and air-sacculitis becomes evident. On postmortem examination, the most consistent findings include thickened, cloudy air sacs (airsacculitis), catarrhal to caseous exudate in the trachea and bronchi, perihepatitis, pericarditis, and fibrinous pneumonia. In cases complicated by secondary infections like E. coli, lesions become more severe, showing a classic “CRD complex.”

Integrated Strategy to Fight CRD
An integrated CRD control strategy combines biosecurity, vaccination, early detection, nutritional support, and precision medication.

Preventive Phase: Reducing the Latent Load
Forlutin 10% (Tiamulin 10%) a high-quality feed additive by Stallen South Asia Pvt. Ltd. serves as the cornerstone for preventive management. Administering it to growers between 7 to 14 weeks of age or just before expected stress periods such as vaccination or peak lay helps reduce the latent load of Mycoplasma. This approach prepares the flock by lowering the pathogen load before the birds reach a vulnerable stage.

Outbreak Management: When Clinical Signs Appear
At the onset of clinical signs indicative of Mycoplasmosis, immediate action is required. Stalmicosin (Tilmicosin Phosphate 250mg) oral solution – a high-quality product manufactured by Stallen South Asia Pvt. Ltd. in its own manufacturing facility to ensure the highest Quality standards, administered via drinking water at 15–20 mg/kg body weight, is highly effective due to its deep lung penetration and prolonged action. This should be continued for 3 to 5 days but not exceeded.

Following the Stalmicosin course, a 24–48hour break should be observed before beginning treatment with Forlutin 80% (Tiamulin 80%) water soluble powder. A dosage of 25–50 mg/kg body weight for another 3 to 5 days helps eliminate residual Mycoplasma and prevents recurrence. Integrating these antimicrobials into a scheduled rotation can significantly reduce disease recurrence and resistance development.

Monitoring and Biosecurity: Supporting the Antimicrobial Strategy
Surveillance using PCR and ELISA tests at regular intervals is vital to detect Mycoplasma presence, especially during and after stress periods. Swab sampling and necropsy examinations for lesions such as air sacculitis or swollen joints provide further evidence. Strict biosecurity—enforcing all-in/all-out practices, staff segregation, and regular disinfection using NADCC, quaternary ammonium compounds, or glutaraldehyde—is essential to support the medical interventions.

What is Stress?
• Stress is a state of worry caused by a difficult situation, a natural response to address challenges & threats in life. Stress is a situation just opposite to Comfort
• Chicken has a limited amount of stored up resources to help adapt to unstable conditions, a challenge or a threat. As long as the challenges are within tolerable limits, chicken manages through its reserves, adjust to the situation & come out with little/no damage
• Stress is the situation when these challenges are more intense or greater numbers, resulting a serious chemical, physical & psychological changes in chicken with harmful consequence

Picture 1
Development stages of Stress in Chicken
– The 3 stages of Stress are ALARM, ADAPTATION & EXHAUSTION
– The first stage is Alarm, a short neurological stage. It is the ‘fright or flight’ reaction based on adrenalin release which triggers the release of glucose into the blood & helps the bird prepare to power to escape
– Adaption is next, where hormones are released to control the long-term effects of stress as they adjust to the new changes in their environment. There may be elevated cortisone levels in the blood, which arrange release of glucose from the body’s reserves of carbohydrates, proteins & fats to help the bird to adjust to the stressor. Diseases associated with long term stress, like diseases of heart, digestive system, metabolic imbalances and susceptibility to disease, are all attributed to high corticosteroid production in managing long term stress.
– The third stage, Exhaustion occurs when chicken does not recover from the stressor, its body reserves depleted, and the normal metabolic function fails with death of the bird.

Once chicken is exposed to stress, it results in immunological or metabolic consequences as below:
– Regression of immune organs/systems leads to Suppressed immune function & increased disease susceptibility
– Reduction of the oxidative metabolic capacity of mitochondria
– Deficit of antioxidant reserves
– Changes in the activity of antioxidant enzymes

Types of Stress in Chicken
– Noticeable Stress
– Disease
– Environment; Heat Stress, Winter Chilling, High Speed Wind (Cyclone), Poor Ventilation
– Starvation or Drinking Water shortage
– Debeaking

– Non-Noticeable Stress
• High performance; rapid growth and peak egg production
• Overcrowding
• Mycotoxin
• Endotoxin
• Wet Litter
• Litter Ammonia
• Poor Quality Feed
• Change of Feed
• Handling
• Transportation
• Vaccination
• Transfer/Mixing/Isolation

Factors responsible for Stress in Chicken:
A. Physiological
1. High Body Weight Gain in Broiler
2. Egg Laying, especially Peak period in Layer & Breeder

B. Nutritional
1. Feed Starvation due to poor supply or inefficient feeding system
2. Drinking Water scarcity
3. Deficiency of Protein, Carbohydrate, fats, Minerals, & Vitamins.
4. Poor quality like Dusty, too Hard or too Big Particle size or old damage feed

C. Environmental
1. Heat Stress
2. Winter Chilling
3. High Humidity
4. Cyclonic Wind
5. Lightening
6. Splash of Rain water

8. Change of attendant

E. Pathological
1. Infections; bacterial, viral, fungal, protozoan, etc
2. Metabolic Disorder like gout, ascites, etc.
3. Endotoxins
4. Mycotoxins
Out of all above, the important & dreaded stresses are all Pathological stress like Infections, Mycotoxins, Endotoxins, Metabolic disorders and 2 environmental stresss, viz. Heat Stress & Cold Stress or Chilling. Please remember when one stress comes after another, then 1 + 1 is not 2 but become 11, means combined stresses are dreaded to chicken.

Heat Stress:
– Heat Stress is a situation when chicken faces difficulty in achieving balance between body heat production & body heat loss
– Chickens lack sweat glands to facilitate latent heat loss by evaporation (perspiration), and have limited un-feathered body surface areas for loss of sensible heat through conduction, radiation, & convection
– Genetics, Feather cover, Age, Body Weight, Egg Production stage & flock maintenance all affect a chicken’s heat tolerance
– Chickens are homeotherms & regulate their body Temperature across a wide range of external Temperature.
– But continuous high climate Temp overwhelm the thermoregulatory mechanisms, resulting imbalance between the amount of metabolic heat produced & their capacity to dissipate body heat in the environment

Picture 2

Picture 3

Physiological response of Chicken to elevated temperature and the Loss in Poultry?
– With Increase in Climate Temp, the Thermal gradient between the Body surface & the surrounding environment lessens with Dissipation of Heat decreasing, resulting Chicken suffering from environment-induced Hyperthermia.
– This increases Respiratory rate (Thermal Polypnea or Panting) to increase Latent Heat Loss via Evaporation of water from the Respiratory tract
– Dehydration is the most harmful effect of panting, which causes Respiratory Alkalosis, acid base imbalance leading to permanent physiological damages
– Alkalosis reduces blood ionized Calcium and ultimately Eggshell mineralization resulting Reduced Egg production, Pale Egg, Soft Shell Eggs, Thin Shell Egg, Increased Broken egg % in Layer & Breeder
– Panting causes Oxidative Stress leading to Immunosuppression, damage of Gut mucosa leading to poor digestion, Dysbacteriosis, Enteritis and increase incidence of secondary infections (Viral like LPAI & ND, Mycoplasma & Bacterial) because of immunosuppression & leaky gut situation.
– Heat Stress reduces feed consumption resulting Poor Body Weight gain in Broiler and reduced Egg production in layer & breeder.
– Heat Stress has Permanent damaging effect; damages the muscles affecting Meat Quality and Lowering Breast Muscle Yield
– Reduces Protein content of the muscles, reduction of muscle pH & Water Holding Capacity and ultimately affecting Juiciness of Chicken Meat
– Disturbs Lipid metabolism by affecting enzyme function in lipid breakdown causing Excess Fat deposition instead of converting to meat
– Heat Stress reduces Male fertility in breeder and affects hatchability severely.
– Heat Stress impact the Expression of Gene related to Growth, Production Performance & Resistance to disease
– Heat stress impairs chicken’s immune system, leading to a reduced response to vaccines, suppressing the production of antibodies and affecting the function of immune cells, particularly lymphocytes, due to the atrophy of immune organs like thymus under high temperatures; heat stress makes it harder for chicken to fight against infections after vaccination and increases their vulnerability to disease
– Heat stress lowers the level of circulating antibodies (IgM & IgG) produced after vaccination, resulting in a weaker immune response against pathogens
– High Temp cause atrophy of thymus, leading to decreased T-cell production and impaired cell-mediated immunity
– Heat stress increases release of corticosteroid and further suppress the immune system.
– Heat stress disrupts the function of immune cells; macrophages & lymphocytes, affecting their ability to recognize and fight pathogens.
– Heat stress damage the intestinal lining, allowing entry of harmful & resident microorganisms into the body system to produce infections.

How to reduce the effect of heat stress in Chicken?
– Poultry House Environment need to made near comfort zone in terms of Temperature, Humidity & Ventilation. Closed Environment Control poultry house is the perfect answer.
– Plantation of Tress on both side of each shed
– Farm construction near forest or under Coconut or Mango Garden
– Reduce Stocking Density in summer to provide more space & more ventilation
– In open house system action must be taken to REDUCE TEMPERATURE at Birds level through

I) Elevated Roof, higher centre height
ii) Coated Roofing materials
iii) Extended side roof overhang to prevent entry of direct Sunlight
iv) Thatching of Roof by Agricultural waste (Paddy & wheat straw, Jute stick, Mustard/seasame harvested dry plant) and Ceiling by Thermostat Aluminium foil
v) Constructing Side Pandals (Leaned Roof Over-hang 1 meter)
vi) Hanging of Gunny with Dipper on both side (2 layers is best)
vii) Ceiling fans in case of Broiler and Circulatory fans in Layer or breeder to improve ventilation
viii) Springler on Rooftop to cool the roof
ix) Fogger inside the shed to reduce inside temperature

Disease Stress:
– Dis ease (Not fine) or Disease is No 1 stress factor in chicken like all other living being. Even unnoticed infection cause stress to force chicken to sit without movement and stay away from feed & water.
– Stress due to Diseases is the most neglected chapter in poultry farming, especially the subclinical or asymptomatic diseases.
– Global Animal Productivity loss due to clinical & subclinical diseases is 20%. Hence, we need to understand the disease stress on chicken and must act to minimize the same.
– Every disease has some specific symptoms but there are some common manifestations to every disease as below:
1. Anorexia or off-feed
2. Dullness, lack of movement or inactive
3. Poor eye reflection
4. Huddling
5. Poor body Weight Growth and poor Egg production
6. Death

Picture 4

Picture 5

Disease Stress produces:
– Uneasy physical status beyond comfort level
– Many physiological changes in the body resulting different symptoms
– Loss of appetite, poor growth & poor production
– Direct or indirect Immunosuppression inviting many other diseases
– Death due to system failure or lack of food for long time anorexia

Mitigation of Disease:
– Practical & 100% Biosecurity to avoid disease entry in to the poultry area.
– Welfare of chicken with respect to space, ventilation, temperature, drinking water & nutrition
– Daily Health monitoring
– Monitoring of Bird’s activity & Feed Intake everyday
– Immediate identification of any deviation in health & production parameter
– Immediate diagnosis at farm & confirmatory from laboratory
– Immediate treatment or necessary action to protect the health & life of chicken

How to Recognize Stress in Chicken
– Vocalization: Chickens have alarm sounds to alert other chickens, like repetitive chirps or screaming.
– Loss of Appetite; poor feed consumption, eating little sometime & stay away from feed in almost all stresses including Heat or Cold stress and disease stress.
– Abnormal Posture: In Heat Stress Birds sits on its belly & breast touching the floor and wings spread apart to lose heat through conduction, convection & radiation. In case of Disease Stress, birds are usually inactive & huddle together near to corner or at areas of Sunlight in open shed.
– Abnormal Behavior: In Heat Stress, there will be too much Panting to lose body heat through evaporation. During disease stress, the birds remain inactive and lying with head down & beak inside litter. Deep breathing is seen in respiratory diseases.
– Water Intake: Heavy increase in case of Heat Stress but reduced in Cold stress and in most diseases.
– Repetitive Behavior: include packing, constant rocking back & forth, head swinging or toe-taping

Effect of Stress in Chicken
– Uneasy state of life, abnormal posture & abnormal activity
– Stressed chickens usually extremely anxious, pick feather & self-mutilate, may cause permanent damage of feather follicles and scar develop on their skin
– Reduced Feed intake & reduced water (except Heat Stress) intake
– Immuno-suppression leading to many diseases from already existing microorganism in the house environment or in the intestine as commensal
– Oxidative stress leading to damage of gut mucosa, poor digestion, dysbacteriosis and enteritis
– Panting & Dehydration
– Excess release of Stress hormone (corticosteroid) leading to further immunosuppression & loss of body condition
– Poor commercial performance like, poor body weight gain & high FCR in broiler and reduced egg production with poor egg shell quality in layer & breeder
– Mortality

Mitigation of Stress in Chicken
– Maintain clean, calm & disease-free poultry house environment
– Noise-free environment; chicken don’t like unusual circumstances
– Avoid environmental stress like winter chilling, summer heat stress, monsoon high humidity inside poultry house through modification of infrastructure & husbandry practice.
– Need conceptual, infrastructural & operational changes to avoid environmental stress with climate change induced global worming situation.
– Avoid compromised ventilation, especially during winter & rainy days in open system farming. Avoid poor ventilation during high humid monsoon & chilly winter months in EC shed especially with compromised structure
– Avoid overcrowding; welfare is most unattended issue creating stress in poultry
– Avoid litter ammonia, wet litter & dust in poultry house
– Follow SOP & behave gently while handling, transfer, mixing, transportation, vaccination and insemination.
– Implement 100% Biosecurity, arrange regular health monitoring & health management. Educate your team about importance of biosecurity in poultry.
– Making sure your flocks have access to safe drinking water and regular supply of recommended fresh nutritious feed during the whole production cycle.

Microscopic pathogens, including bacteria, viruses, fungi, and parasites, pose significant threats to poultry health, with avian influenza being a major concern due to its high mortality, economic impact, and zoonotic potential. The disease is caused by Influenza A virus belonging to the family Orthomyxoviridae. Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N). There are 18 different hemagglutinin subtypes and 11 different neuraminidase subtypes (H1 through H18 and N1 through N11, respectively). The highly pathogenic strains such as H5N1, H7N9, and H9N2 have been reported to cause severe disease. The virus spreads through direct contact with infected birds, contaminated feed, water, and fomites, while wild migratory birds serve as natural reservoirs, enabling global transmission. Highly pathogenic avian influenza can lead to near-total flock mortality, significantly disrupting poultry production and trade. Additionally, zoonotic strains such as H5N1 and H7N9 can cause severe respiratory illness, pneumonia, multi-organ failure, and high fatality rates in humans, necessitating global surveillance by organizations like the World Health Organization (WHO).

Poultry farms constantly face the risk of Avian influenza and other infectious diseases that persist in dust, droppings, and farm waste, making biosecurity a fundamental component of disease prevention. Biosecurity measures serve as the first line of defence, preventing pathogen entry and transmission through stringent hygiene, controlled farm access, and optimized housing conditions. Effective biosecurity minimizes outbreaks of avian influenza, Newcastle disease, duck plague, and bacterial infections such as fowl cholera and mycoplasmosis, which compromise poultry health, reduce productivity, and weaken consumer confidence.

Given the increasing incidence of avian influenza worldwide, including India, strengthening biosecurity is imperative to safeguard poultry health and public safety. Disease prevention strategies must integrate high-quality stock, proper housing, clean feed and water, regular disinfection, and restricted farm access. Additionally, modifying industry practices in poultry production, transport, and marketing is essential to curb disease spread. Veterinary authorities must continuously evaluate and refine biosecurity measures in high-risk areas while considering economic and social impacts. Several biosecurity measures have been implemented or require further revision in Asian countries, including India, to effectively control avian influenza and ensure sustainable poultry production. Above all, biosecurity must be a continuous effort rather than a reactive response to outbreaks.

A well-structured, proactive approach remains critical for preventing disease outbreaks, ensuring industry stability, and minimizing zoonotic risks.

Key Biosecurity Measures in the Poultry Industry
1. Marketing Systems: Live bird markets serve as critical points for avian influenza (AI) transmission due to continuous operation, overnight poultry retention, and the reintroduction of unsold birds to farms. These practices facilitate pathogen circulation. Implementing a mandatory market rest period of 24 hours in a week, accompanied by thorough cleaning and disinfection, is essential to mitigate viral persistence and spread.

2. Species Segregation: Domestic waterfowl and quail act as reservoirs for avian influenza viruses. Their cohabitation, transportation, and marketing alongside other poultry should be restricted to minimize interspecies transmission. Additionally, swine reared in proximity to infected poultry farms are found to be infected with HPAI (Highly Pathogenic Avian Influenza) therefore should undergo systematic veterinary surveillance. In cases of confirmed avian influenza infection, culling of affected herds is recommended to prevent viral reassortment and potential zoonotic spillover.

3. Farming Practices: Extensive poultry rearing systems, particularly in village settings, pose a heightened risk for avian influenza introduction due to their lack of biosecurity controls. Strategic vaccination programs targeting backyard poultry can enhance herd immunity. Commercial farms should adhere to an ‘all-in, all-out’ production model to reduce pathogen exposure and poultry workers must adhere to strict biosecurity protocols, including cleaning, disinfecting, or changing protective clothing, equipment, and footwear before entering and after leaving farms.

4. Transport Biosecurity: Transport cages and egg containers should be constructed from non-porous materials such as plastic or metal over wooden cages to facilitate effective disinfection. To prevent environmental contamination and disease spread, bio-secure transport protocols should be implemented. This includes minimizing faecal contamination during poultry unloading, ensuring transport cages are cleaned and disinfected before returning to farms, and using easily sanitized materials for transporting table eggs, fertile eggs, and day-old chicks.

5. Compartmentalization: In regions where avian influenza is endemic, creating compartmentalized poultry populations with distinct health statuses is essential for disease control and international trade compliance. This requires strict biosecurity measures, including traceability of fertilized eggs, certified hatchery and feed sources, vermin control, and regulated transport. Poultry operators must maintain detailed records of suppliers, egg crate circulation, employee responsibilities, and transport activities to ensure compliance and effective disease containment.

Mitigation of Stress through Managemental Interventions
While biosecurity is crucial for disease prevention, stress reduction is equally important in enhancing poultry resistance to infections, including avian influenza. Environmental factors such as high temperatures, ammonia build-up, overcrowding, feed deprivation, handling, and transportation induce physiological stress, compromising immunity. Strategies such as adjusting feeding schedules, providing cool drinking water, supplementing essential nutrients, and optimizing dietary energy and amino acid levels help mitigate heat stress. Maintaining appropriate temperature, ventilation, and humidity is vital for flock health, especially in regions with high heat and humidity. Since wet litter contributes significantly to ammonia production, proper litter management, ventilation, and dietary adjustments are necessary to reduce ammonia levels and support biosecurity measures.

Nutritional Biosecurity Measures
Poultry immunity depends on proper nutrition, as essential nutrients regulate immune cell activity and function. Balanced diets rich in proteins, vitamins, trace minerals, and energy sources are critical for disease resistance. Probiotics enhance immunocompetence by stimulating antibody production, while prebiotics selectively promote beneficial gut bacteria, improving immune function. Additionally, mycotoxins in poultry feed suppress immune responses, making birds more susceptible to infections. Strict feed quality control and mycotoxin mitigation strategies should be integral to biosecurity programs.

Hygienic Disposal of Poultry Waste
Poultry operations generate waste, including dead birds, broken eggs, manure, litter, and contaminated equipment, which serve as reservoirs for pathogens. Proper disposal methods include burial, incineration, rendering, and composting.
Burial is effective but requires a 90-day period for pathogen deactivation before use as fertilizer. Incineration is reliable but often limited by facility size. Open burning is costly and environmentally unfavourable. Rendering is viable if decontamination is ensured, though private facilities may be reluctant to handle infected material. Composting within farm premises minimizes the risk of disease transmission during transport. Additionally, high-risk practices like using contaminated water and recycling untreated poultry waste should be strictly prohibited.

Wild Bird and Vector Control for Disease Prevention
Wild birds, particularly waterfowl, act as reservoirs for avian influenza and other pathogens, and play an important role in introducing infections to poultry farms. Effective biosecurity includes wild bird-proofing quarantine facilities and preventing their access to contaminated areas. Rodent control is equally essential, as rats and mice serve as mechanical carriers of the pathogens. A structured eradication program should minimize their dispersal from infected sites. Flying insects also contribute to disease transmission; thus, integrated pest management strategies should be implemented to reduce their presence in poultry sheds.
Immunomodulation through Nutritional Supplementation and Genetic Strategies
Regular supplementation of vitamins, minerals, and proteins strengthen poultry immunity and should be a core component of modern biosecurity. Nutrient deficiencies compromise resistance, increasing vulnerability to avian influenza and other diseases. As the influenza virus rapidly mutates and can exist as various subtypes and pathotypes, it questions the efficacy of existing vaccines and antivirals, and hence, genetic interventions offer a promising alternative. Screening poultry populations for disease-resistant genes, particularly in native breeds, and incorporating these traits through selective breeding can enhance flock resilience against infections.

Vaccination Strategies for Avian Influenza
Vaccination integrated with biosecurity measures can act as a critical tool for influenza control. Vaccines should provide adequate protection and minimize virus shedding. Vaccination programs coupled with virological and serological surveillance can be used to effectively detect viral mutations and assess vaccine effectiveness. In past influenza outbreaks in Maharashtra, Gujarat, and Madhya Pradesh, India successfully controlled the disease through culling and biosecurity measures. Establishing vaccine banks and enhancing domestic vaccine production are essential for rapid response to outbreaks. Policymakers must decide on vaccination strategies based on epidemiological data and national disease trends.

Strengthening Quarantine and Flock Profiling
Strict quarantine protocols are crucial in preventing disease introduction through newly acquired birds. Newly introduced poultry should be isolated for at least 21 days, monitored for clinical symptoms, and tested (blood, faecal, and nasal swabs) before integration with existing flocks. Beyond farm-level quarantine, strict regulations should be enforced to control cross-border movement of live poultry and poultry products.

Conclusion:
Effective biosecurity is the cornerstone of bird flu prevention and control, serving as the primary defence against disease outbreaks in poultry. Raising awareness among poultry farmers, industry stakeholders, and policymakers is essential for strengthening biosecurity at all levels. Training programs for grassroots poultry managers should be prioritized to ensure the proper implementation of preventive measures. In addition to immunity-boosting strategies and advancements in disease control, continuous surveillance of avian influenza and other infectious diseases is crucial. A proactive and well-enforced biosecurity framework not only safeguards poultry health and industry stability but also minimizes public health risks associated with zoonotic disease transmission. By integrating stringent biosecurity protocols with modern disease prevention strategies, the poultry sector can achieve long-term sustainability and resilience against emerging threats like avian influenza.

Stress comes in many forms and seems to affect the performance of birds. The term “stress” is used to describe the detrimental effect of variety of factors on the health and performance of poultry (Rosales, 1994) Or “Stress is the nonspecific response of the body to any demand”, whereas stressor can be defined as “an agent that produces stress at any time”. Therefore, stress represents the reaction of the animal organism (i.e., a biological response) to stimuli that disturb its normal physiological equilibrium or homeostasis (Selye, 1976). The commercial high yielding breeds are more susceptible to stress and diseases. Stress represents the reaction of the animal organism (i.e., a biological response) to stimuli that disturb its normal physiological equilibrium or homeostasis. The importance of animal responses to environmental challenges applies to all species. However, poultry seems to be particularly sensitive to temperature-associated environmental challenges, especially heat stress. Understanding and controlling environmental conditions is crucial to successful poultry production and welfare. Heat Stress not only causes suffering and death in the birds, but also results in reduced or lost production that adversely affects the profit from the enterprise.

Heat stress or any type of Stress have side effect on Vital organs heart, brain, kidneys, liver, and lungs.
Heat Stress adverse effects on liver
The liver is pivotal organ of metabolic activity, which performs essential cellular functions containing the balance of energy metabolism, biosynthesis of vitamins and minerals, and ammonia detoxification (Schliess et al., 2014). Elevated blood flow transfers from the hepato-splanchnic region to respiratory muscles and superficial body tissues to accelerate heat dissipation and decrease body temperature under heat stress, therefore, liver is more sensitive to heat stress (Hai et al., 2006; Crandall et al., 2008). It has been reported that heat stress caused liver fat accumulation and inflammation, and impaired liver function in broiler.

Heat stress adverse effects on respiratory system
Heat stress can cause damage to the lung tissue of broiler chickens by disrupting the integrity of the blood-air barrier and increasing permeability diseases can cause different degrees of lung damage Mammals mainly rely on sweat glands to dissipate heat and maintain body temperature balance (Yahav, 2015), but poultry lack sweat glands, so they primarily dissipate heat through respiration when the temperature is too high (Bell et al., 2001). High-frequency breathing leads to increased susceptibility of lung tissue damage in a heat stress environment. Damage to the blood-air barrier can lead to increased lung permeability, impaired oxygen and carbon dioxide exchange function, and induce respiratory difficulties (Wang et al., 2020), further leading to various lung diseases such as tuberculosis and pulmonary inflammation (Research has shown that heat stress causes lung injury and results in the upregulation of various proinflammatory cytokines, including tumor necrosis factor.

Conclusion
High ambient temperature has emerged as a major constraint for the future development of the poultry industry, especially in the tropics and subtropics. The scarcity of resources coupled with harsh environmental conditions is the most crucial predicaments in the way to rationalize optimum production of broiler. Heat stress disturbs the physiological biochemistry of the broiler which ultimately reduces feed intake and feed efficiency which ultimately results in reduced performance and productivity. Under hot environmental conditions, feed utilization is disturbed by the deposition of fat and oxidative stress. In addition, changes in blood cells, acid-base balance, immune response, liver health, and antioxidant status are some of the major dynamics altered by heat stress.

Alleviating the Adverse Effects of Heat Stress is mandatory to achieve Production & performance poultry Business.

Water Hygiene Challenges and Management in Commercial Poultry Farming during Summer Season

Dr Davendar Singh Kalwani, Technical Sales Manager, Intracare SEA Pvt Ltd

Introduction:
Summer season brings with it extreme challenges for the poultry industry. Among all the prevailing issues, water hygiene remains the top priority, as far as poultry production is concerned. Quality of water will in general, have a direct bearing on poultry’s health and production. Good quality water is important for poultry’s growth, reproductive performance, and general well-being. The prevailing high temperatures coupled with an increased microbial activity during the summers obviously make it tough to maintain the desirable standards of water hygiene. This article attempts to understand the risks involved and the strategies to manage the water hygiene in this summer in a better way. The article also tries to identify the factors contributing to waterborne microbial contamination and understand the impacts of water contamination on poultry health and welfare. Awareness of the peculiar dynamics of summer management, in terms of water hygiene, can help farmers in preventing some of the losses that are usually suffered by them during the summer and throughout the year.

Impact of summer season on water quality:
During summer, various environmental factors can affect the quality of water. The rise in temperature of water is the most important factor. As the water temperature increases, it creates optimal conditions for microbial growth. Mesophilic bacteria including major pathogens proliferate rapidly in such conditions, hence increasing the risk of water contamination in poultry production. These microbes might lead to severe illnesses and reduced performance in terms of growth and reproduction.

Moreover, the elevated water temperature accelerates the decomposition of organic matter which serves as a nutrient source for various microorganisms. Due to this rapid decomposition in warmer temperatures, the level of nutrients, such as nitrogen and phosphorus in water increases along with release of dissolved solids which further alters the water composition negatively.

Additionally, this can fuel the algal bloom in underground water reservoirs. Some species of algae produce toxins that are harmful to both animals and humans if ingested. Also, as algae die and decomposes it hastens the degradation of water quality.

In addition to microbial contamination and algal blooms, summer conditions can also aggravate other water quality issues in poultry operations. Reduced rainfall and drought conditions in certain regions can result in lower water levels in reservoirs and water bodies. Lower water levels concentrate pollutants, such as nutrients, chemicals, and sediment, leading to higher concentrations in the remaining water. This can further degrade water quality and increase the risk of contamination for poultry.

Biofilm as a hidden threat:
Formation of biofilm during summer is another crucial aspect involved in degrading water quality particularly in water pipelines. Biofilms is a slimy layer consisting of complex communities of microbes that attach to surfaces of water pipes, tanks, and drinkers. Warm climate can enhance the growth and proliferation of various bacteria, easing the formation of such biofilms. These biofilms pose several challenges to the quality of water and poultry health. It provides protection for microbes inside it by shielding them from disinfectants and making them more resistant to removal, this allows pathogens to persist in the water systems for long durations making itself a source of infection.

Biofilms can also cause deterioration of water infrastructure; its accumulation might lead to corrosion of pipes and fittings which can compromise the integrity of water distribution system. Additionally, it can cause blockages and reduce the flow of water and thus affecting water flow to drinkers which can lead to dehydration in birds.

Furthermore, biofilms act as a reservoir for pathogens, releasing them into the water intermittently and perpetuating the cycle of contamination. This can pose a continuous threat to poultry health, increasing the likelihood of disease outbreaks and impacting the overall productivity of the operation.

Effects of poor water quality on poultry production:
1. Biofilm inside water pipeline may reduce intake, causing dehydration and poor growth.
2. Biofilms can release pathogens, affecting bird health and productivity.
3. Contaminants may lead to digestive issues, diarrhoea, and poor growth.
4. Poor quality of water can affect egg quality resulting in thin shelled eggs and reduced hatchability in fertile eggs.
5. Stress from poor water quality drops reproductive performance in poultry flocks.
6. Mortality rates can increase due to stress, dehydration, and disease susceptibility.
7. Water contaminants compromise vaccine efficacy, leaving birds vulnerable to infections.
8. It might worsen the effect of concurrent viral or any other diseases.
9. Clogged delivery systems can hamper vaccine administration, risking inadequate immunity in poultry.
10. It can increase the chances of vertical transmission of bacterial diseases in progeny.

Management Strategies for Summer Water Hygiene:
Following strategies may be followed to ensure quality drinking water to poultry birds:
1. Regularly clean the water sources, pipes, and drinkers to prevent biofilm and pathogen buildup.
2. Test the water quality regularly for pH, TDS, and microbial contamination.
3. Use of good quality water disinfectant and sanitizers and follow manufacturer guidelines.
4. Control water temperature to prevent microbial growth.
5. Minimize water wastage by fixing leaks and optimizing delivery systems.
6. Educate farm staff on water hygiene.
7. Maintain records of cleaning schedules and water quality tests.

Ensuring water quality at poultry farms:
Along with all the management strategies, the most crucial step is pipeline cleaning and water sanitation. There are many chemical agents available for the same purpose. Choosing the best water sanitizer and cleaning agent should be based on several characteristics.
When it comes to pipeline cleaning methods, the following characteristics are desirable:
1. Efficiency: The cleaning method should effectively remove biofilms, mineral deposits, sediment, and other contaminants from water pipelines to maintain optimal water quality and flow rates.
2. Non-Corrosive: Cleaning agents or procedures should not corrode or damage pipeline materials, ensuring the longevity and integrity of the water distribution system.
3. Accessibility: Pipeline cleaning methods should be accessible and practical for poultry producers, whether through manual cleaning procedures or automated cleaning systems.
4. Frequency: The cleaning frequency should be appropriate to prevent biofilm formation and ensure consistent water quality for poultry health and performance.
5. Validation: Cleaning procedures should be validated to confirm their effectiveness in removing contaminants and maintaining water sanitation standards.

When considering water sanitizers for poultry operations, several characteristics are essential to ensure effective and safe water management:
1. Broad-Spectrum Activity: An ideal water sanitizer should have broad-spectrum activity against a wide range of bacteria, viruses, fungi, and other pathogens commonly found in poultry drinking water. This ensures comprehensive protection against disease-causing organisms.
2. Non-Toxic and Safe: The sanitizer should be non-toxic to poultry and humans when used at recommended concentrations. It should not leave harmful residues that could affect bird health or compromise food safety.
3. Residue-Free: After application, the sanitizer should degrade into non-toxic by-products or dissipate without leaving any harmful residues in the water or water distribution system.
4. Stability: The sanitizer should remain stable under varying environmental conditions, including temperature fluctuations and water pH levels, to maintain its effectiveness over time.
5. Compatibility: It should be compatible with commonly used materials in poultry water systems, such as PVC, polyethylene, and stainless steel, to prevent corrosion or damage to pipelines and water equipment.
6. Ease of Application: The sanitizer should be easy to apply and should not require complex equipment or procedures for effective use. This ensures practicality and efficiency in poultry farm operations.
7. Regulatory Compliance: The sanitizer should comply with regulatory standards and guidelines set forth by relevant authorities, ensuring its safety and efficacy for use in poultry production.
8. Environmental Impact: Consideration should be given to the environmental impact of the sanitizer, including its biodegradability and potential effects on water quality in surrounding ecosystems.

Based on these characteristics, selecting a suitable option is very perplexing. In general, quaternary ammonium salts (commonly called quats) and hydrogen peroxide fulfil almost all the requirements but they have some drawbacks as well. Hydrogen peroxide is an unstable compound and loses its efficacy in very short period making it difficult to get uniform results across pipeline. Quats are effective for water sanitation, but they have limited action on biofilms particularly mature ones. However, 50% stabilized hydrogen peroxide is an excellent choice as it easily overcomes the above problems. Its broad-spectrum effectiveness, safety, non-corrosive properties, long shelf-life, and environmental compatibility make it an indispensable tool in safeguarding the health and profitability of poultry flocks, particularly in the challenging conditions of the summer season.

Conclusion
In conclusion, managing water hygiene effectively is among top priority for commercial poultry farmers, especially during the challenging conditions of summer. Summer’s heat and increased microbial activity threaten water quality. Regular cleaning, disinfection, temperature control, and water testing can help combat these threats successfully. Minimizing water wastage waste, staff training, and record-keeping further strengthen water hygiene plans. By proactively managing water, poultry farmers ensure the long-term health and profitability of their flocks.

It was first discovered in the juice of sugar beets. Naturally accumulated in plants as osmolyte to protect against salt and temperature stress. Derivative of glycine (amino acid). Neutral molecule with bipolar structure (zwitterion) as shown in Fig. 1 contains three methyl groups.

2. Betaine functions as (mode of action):
A. Methyl donor – methyl groups used for protein synthesis and other metabolic processes. Methyl groups play a pivotal role in several cellular processes, including DNA methylation, synthesis of phosphatidylcholine, and protein synthesis. Choline and betaine are both capable of donating methyl groups. However, for choline to do so, it must first be converted into betaine as shown in Fig. 2. In poultry, the capacity to synthesize betaine from choline is limited, thus making dietary supplementation the primary source.

Betaine can substitute for choline in performing the following functions:
1) Regulating fat metabolism in the liver to prevent abnormal fat accumulation in hepatocytes.
2) Serving as a methyl donor for the formation of methionine and creatine, through its involvement in the transmethylation pathway.
Betaine cannot replace choline in the function of maintaining cell membrane and structure as an emulsifier to transport lipids, since choline is a constituent of phospholipids. Similarly, betaine cannot replace choline as a precursor of acetylcholine in the transmission of nerve impulses.

B. Osmo-regulator: – ability to bind and retain water in a reversible manner.
Osmolytes are compounds that aid in the regulation of osmotic pressure within cells and tissues, playing a crucial role in preserving cellular integrity.
Dehydration, disease, heat stress, and other factors can cause alterations in the water content of cells. Osmolytes can be either inorganic ions such as Na+, K+, Cl-, or organic compounds such as amino acids, certain sugars, and betaine. Betaine plays a crucial role in stabilizing cellular metabolic function during periods of stress, preserving the cell’s capacity to uptake nutrients, unlike osmolytes such as Na+, K+, and Cl-. Moreover, it offers protection to intracellular enzymes against osmotic inactivation.

3. Heat stress
Heat stress is a major challenge in poultry production, especially during the hot summer months. It occurs when birds face difficulty in achieving a balance between body heat produced and heat loss. This imbalance can lead to several health issues and production losses.

4. The Role of Betaine in Enhancing Poultry Health During Heat Stress.
a) Betaine aids in preserving intestinal integrity by facilitating water retention, increasing cell volume, promoting anabolic activity, and maintaining cellular integrity as shown in fig. 4. which are Representative photomicrographs of the ileum after 10 days of the experiment from broilers fed a control diet (CON, A and C) and betaine (BET, B and D) on villous height under thermoneutral (TN, A and B) or after 10 days being exposed to heat stress (HS, C and D).

b) Betaine has three methyl groups in its structure and donates them in various metabolic reactions, which can spare compounds like methionine, choline, and folic acid. Therefore, supplementing with betaine may reduce the need for these nutrients.

c) The growth rate of poultry birds is enhanced by betaine, which conserves energy that would otherwise be expended on the Na+/K+ pump and Calcium pump in high temperatures. This conserved energy can then be directed towards growth.

d) Betaine enhances the concentration of beneficial short-chain fatty acids, such as acetic and propionic acid, which are vital to host bacteria like Lactobacillus and Bifidobacterium in poultry. This improvement enables these bacteria to effectively inhabit the caecum and inhibit the colonization of harmful bacteria in the intestinal tract.

e) Betaine supplementation in laying hens leads to an increase in daily egg mass production, reduces thin eggshell issues which are related to heat stress, and helps to enhance serum concentrations of estradiol and melatonin.

f) Trouw Nutrition’s Betaine is proven to elevate production performance even under heat stress conditions, notably increasing breast meat percentage through the provision of essential methyl groups, as depicted in Fig. 5.

Recommended Dosage:
For broiler, layer, and breeder birds: 0.5 to 1 kg per ton of feed. However, in challenging conditions such as heat stress, the Betaine dosage can be increased to up to 2 kg per ton of feed.
g) Betaine has been found to significantly enhance hematological parameters, including RBC and platelet count, while reducing the number of heterophils and increasing the number of lymphocytes. The reduction in lymphocyte count during heat stress is attributed to the rise in inflammatory cytokines, which stimulate hypothalamic production of corticotrophin releasing hormones.
h) Betaine aids in the expansion of intestinal mucosa, thereby enhancing the absorption and utilization of nutrients, which results in improved digestibility of crude protein, crude fiber, ether extract.
i) Studies have demonstrated that betaine interacts with lipid metabolism by promoting the oxidative catabolism of fatty acids through its involvement in carnitine synthesis. Therefore, betaine can be utilized to increase the proportion of lean meat and reduce fat in poultry carcasses.
j) Betaine acts as an osmoregulatory in the intestine, optimizing water and salt balance within cells for efficient nutrient absorption and reducing litter moisture. It increases villus height, protecting enterocytes during challenges like coccidiosis, and strengthens the gut, reducing damage during infections as shown in Fig. A, B and C.
The various effects described above are either directly or indirectly linked to betaine’s osmoregulatory function and its role in methionine biosynthesis.
Betaine emerges as a pivotal component in poultry health management, particularly in the face of heat stress challenges. Originating from sugar beets, its molecular structure rich in methyl groups facilitates its dual function as a methyl donor and osmoregulator, essential for maintaining cellular integrity and supporting metabolic processes. Amidst heat stress conditions, Betaine supplementation showcases remarkable efficacy, preserving intestinal integrity, conserving energy expenditure, and enhancing production performance. Its multifaceted benefits extend to improvements in hematological parameters, nutrient absorption, and lipid metabolism. With its proven effectiveness and adherence to stringent quality standards, Betaine stands as a crucial asset in optimizing poultry health and performance under challenging environmental conditions, exemplifying the potential of innovative nutritional strategies in safeguarding livestock welfare and productivity.
