Abstract:
In the modern poultry industry, ensuring optimal health and productivity in layers, breeders, and broilers under various stress conditions is vital. Feed additives like choline chloride, synthetic betaine (anhydrous and HCl forms), and natural betaine are used to enhance performance. However, synthetic choline chloride and betaine often contain residues of ethylene oxide and trimethylamine (TMA), which pose significant risks to poultry health, including fatty liver syndrome, reproductive challenges, and respiratory hazards. The chemical synthesis of these additives highlights the adverse effects of residue contamination and explains why natural Betaine (anhydrous )(Hepatron/Beta Pro BL) is the superior choice.

1. Chemical Synthesis of Choline Chloride, Betaine, and Betaine Hcl
Choline Chloride Synthesis:
Choline chloride is produced by reacting ethylene oxide with trimethylamine, followed by neutralization with hydrochloric acid:
C2H4O + (CH3)3N + HCl —- (CH3)3N+CH2CH2OH.Cl-

Synthetic Betaine Anhydrous Synthesis:
Betaine is synthesized by methylating glycine with trimethylamine:
NH2CH2COOH + 3(CH3)3N—– (CH3)3N+CH2COO-

Betaine Hydrochloride Synthesis:
Betaine HCl is formed by reacting betaine with hydrochloric acid:
(CH3)3N+CH2COO- + HCl —– (CH3)3N+CH2COOH.Cl-

2. Risks Associated with Ethylene Oxide and Trimethylamine Residues
Ethylene Oxide (EO): permissible limit 0.2mg/g
Source: Ethylene oxide is used as a key reactant in choline chloride synthesis.

Risks and Effects:
Fatty Liver: Ethylene oxide residues exacerbate lipid accumulation in the liver, leading to fatty liver syndrome, impairing metabolism and egg production in layers.
Reproductive Challenges: In breeders, EO residues can induce oxidative damage to ovarian tissues, affecting fertility and hatchability.
Respiratory Hazards: Chronic exposure to ethylene oxide fumes or residues increases oxidative stress in respiratory tissues, leading to reduced lung function and increased susceptibility to respiratory infections.

Trimethylamine (TMA): permissible limit 10 mg/kg
Source: TMA is used as a methyl donor in the production of choline chloride and synthetic betaine.

Risks and Effects:
Fatty Liver: Excess TMA disrupts lipid metabolism by impairing the synthesis of very low-density lipoproteins (VLDL), leading to hepatic fat accumulation.
Reproductive Challenges: In breeders, TMA residues interfere with reproductive hormone balance, reducing fertility and chick quality.
Respiratory Hazards: Volatile TMA emissions irritate the respiratory tract, causing chronic respiratory distress in broilers and layers, especially in poorly ventilated environments.

3. Challenges of Synthetic Additives in Poultry Nutrition
Residue Toxicity: Synthetic choline chloride and betaine often leave traces of ethylene oxide and TMA, causing long-term health risks.
Liver Dysfunction: These residues impair liver detoxification and metabolic efficiency, leading to reduced productivity.
Limited Stress Resilience: Synthetic forms lack the bioactive properties of natural betaine, making them less effective in managing stress.

4. Natural Betaine (anhydrous) (Hepatron/Beta Pro BL): A Safer and More Effective Solution
Residue-Free and Safe: Hepatron/Beta Pro BL, derived from natural sources, is free of ethylene oxide and TMA residues, eliminating the associated risks of liver damage, reproductive issues, and respiratory stress.
Superior Liver Support:
– Enhances lipid metabolism, preventing fatty liver syndrome.
– Boosts detoxification pathways to handle feed-related toxins more effectively.
Enhanced Stress Management:
– Natural osmoregulatory properties stabilize cellular hydration under heat and osmotic stress.
– Promotes better feed conversion and growth performance.

5. Correlation Between Natural Betaine and Poultry Health
Fatty Liver Syndrome Prevention: Natural betaine spares choline and methionine in feed, reducing the metabolic burden on the liver and enhancing lipid transport efficiency.
Reproductive Health Support: Hepatron/BetaPro BL optimizes methylation pathways, improving ovarian function, egg production, and hatchability in breeders and layers.
Respiratory Protection: Unlike TMA-containing additives, Hepatron/Beta Pro BL improves cellular hydration and stress tolerance, protecting the respiratory tract from environmental and metabolic stress.

6. Stress in Poultry: A Multi-Faceted Challenge
Types of Stress in Poultry:
1. Environmental Stress: Heat & cold (Environment) stress in broilers & layer
2. Nutritional Stress: Imbalanced diets and mycotoxin contamination.
3. Physiological Stress: Vaccination, debeaking, and transportation.
4. Production Stress: Egg production in layers and rapid growth demands in broilers.

Role of Hepatron/Beta Pro BL in Feed application for Stress Mitigation:
Layers: Reduces egg drop during heat/Cold stress (Environment physiologica stress/ and improves shell quality.
Breeders: Enhances fertility and hatchability under environmental and nutritional stress.
Broilers: Improves growth performance and livability during transportation and heat stress.
Application of Hepatron/BetaPro BL in Drinking water: 6 hours improved water intake during treatment & outbreak condition it is advisable apart from stress mitigation what mentioned in Feed application for quick support as a clinical Nutrition

7. Why Natural Betaine (Hepatron/Beta Pro BL) is Superior

Conclusion
Residues of ethylene oxide and trimethylamine in synthetic choline chloride and betaine pose significant risks to poultry health, including fatty liver, reproductive challenges, and respiratory hazards. Natural (anhydrous )Betaine (Hepatron/Beta Pro BL) offers a safer, residue-free alternative with superior bioavailability and efficacy. By supporting liver function, improving reproductive outcomes, and protecting respiratory health, Hepatron/Beta Pro BL proves indispensable for sustainable and profitable poultry farming.

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.

Grading in poultry breeding is the process sorting birds into categories based on their body weights. Grading is the process of sorting individual birds into categories based on bodyweight (super light, light, average, heavy) so that birds within respective categories can be managed back to standard. Grading is the process of shorting of all individual birds in a flock (both Male & Female separately) into 3 sub-populations based on body weights (physiological state) so that each group can be managed back to the standard to have perfect uniformity in the whole flock at the point of Lay (POL). A uniform flock is easier to manage than a variable one; birds in similar physiological stale will respond more similarly to managemental factors.

Background of Grading
There is always a natural variation in a flock, even at day old. At placement, the chick body weight in a flock should have minimum variation. As chicks grow, the variation in the flock increases further due to difference of response of individual birds to factors like vaccination, disease, differing competitiveness of feed, etc. The increased variation reduces overall flock performance and makes the flock management much more difficult.

Understanding the Principles of Grading
Grading is a systematic process that adheres to well-defined principles. It’s a great way to improve the uniformity of a flock!

With grading, the flock is separated, and groups of smaller and bigger birds are formed to improve the total flock uniformity. The grading principles serve as guidelines to ensure consistency, and fairness while classifying birds. The primary principles of grading are the following:

1. Objectivity: Grading should be based on measurable and observable characteristics, minimizing subjective judgments.
2. Traceability: Detailed records should be maintained to track the grading process and facilitate future analysis.
3. Continuous Improvement: Grading practices should be regularly reviewed and updated to incorporate advancements in breeding management.

Purpose
Grading improves uniformity in a flock by separating birds into groups based on their weight so that they can be managed back to the standard.

Benefits
A uniform flock is easier to manage because birds in similar physiological states respond similarly to management.

When to grade
Grading is usually done when the flock is 7–14 days old, and then again at 4, 8, and 12 weeks of age. It’s recommended to grade as soon as possible so that the birds can recover from growth retardation.

How to grade
To grade, you can:
1. Weigh a minimum of 2% of the flock to calculate the average weight and variation in body weight.
• Measure the variation in body weight using the coefficient of variation (CV%) or uniformity (%).
• Separate the birds into categories based on their weight.
• Manage each group to bring them back to the standard weight.

Grading Procedure
Depending on the uniformity 3 to 4 sub-populations may be made; Heavy, Medium, Light & Super light (if necessary). Some breeder houses have fixed pen or partitions and some houses has adjustable partitions; in both cases at least one pen shall be left empty during chick placement for Grading operation. It is better to have adjustable Partition and divide the whole house in 4 parts for Female & 4 parts for Male; with 2 parts each for medium size group (usually over 65% of total population), One part each for Heavy & Light Weight group for both Male & Female. Arrange Brooding in one part each for Male & female separately. Start grading on 8th day itself and shift them in different pen, keepingthe lighter group at the entry side. With advancing age & body weight, arrange 100% grading at the end of 4, 8 & 12 weeks and give floor space accordingly in the respective pen. In case of fixed pen, calculate the floor space, no of feeder & drinker as per maximum no of birds to place after grading. Similarly, in case of adjustable pen adjust the size as per no of birds to be housed along with sufficient no of feeder & drinkers. If stocking density in a pen is not adjusted with floor space, feeder & drinker space, then grading will cause more problem.

Variation in a flock can be measured by 2 different ways:
1. Coefficient of Variation (CV%) – this measured the variations of body weight within the flock, the flock with lower CV’s is a less variable flock.
2. Uniformity% – this measures the evenness of body weights within a flock, the higher the uniformity the less variable the flock is.

Key Issues during Grading:
• Start Grading of Male & Female simultaneously @ 2nd Week or 29th day.
• A successful Grading should minimize the variability in graded flock than the original flock with the CV% shall be around 8 and Uniformity above 80%.
• Each sub-population should be re-weighted & counted to confirm the Av Body Wt and CV%/ Uniformity so that projected (re-scheduled) target body weights & Feeding rates can be determined.
• Inaccurate bird counting will lead to incorrect quantity of Feed, which invite future problem
• Each sup-population should have own dedicated feeding system. Otherwise, supplementary feeding must allow even distribution of feed & adequate feeding space per bird.
• Ensure the stocking density, feeding & drinking space are consistent as per guidelines after grading; specially for the adjustable size pen.

Flock Management after Grading:
• Following grading, the flock need to be managed to achieve targeted body weight in graded group in uniform & coordinated manner. Post grading management to maintain uniformity within graded pen is more important than the grading itself. The most important issue is the post grading management results in the birds converging to a common target body weight at Transfer to laying house.
• Post Grading Feed Quantity should be adjusted to individual pen and graded birds body weights to bring each sub-population gradually back to the target line.

Challenges for Grading
• Grading is often seen as a herculean task. Add to that the misconception that it involves too much work for a very little return, and there are numerous reasons why farm owners do not want to grade their flock.
• Increased costs due to more labor.
• Stressful for birds to move between the pens.
• Feeder & drinker configurations. Managing feed times.

Take Home Message
• Feed level must be recalculated on a weekly basis calculating for changes in liveability.
• Feed recalculation twice a week gives excellent results specially for Light weight group where higher increase level is required.
• Feed calculation based on individual pen birds Av Body Wt & bird numbers
• Feed level should never be reduced
• Feed level for Light Wt group should remain same first week post grading owing to the fact that reduced competition from heavier birds will give a good amount extra feed to all birds.
• Smaller for Heavy Wt Bird group
• Greater for Lighter Wt Bird group
• Standard for Medium Wt bird group
Never hold feed increment for any group for more than 2 weeks

Post Grading: Continuous Improvement
Flock grading is an ongoing process that requires regular review and refinement. Post-grading activities are essential for continuous improvement and sustained breeding success.

By mastering flock grading and adhering to best practices, poultry breeders can achieve optimal flock management, genetic progress, and long-term profitability in their breeding operations.

With the expansion of the poultry industry, farm owners have looked further in detail about ways to improve the hatching eggs and chick output. With increased research, what we know is that one certain way of increasing the overall performance is by maintaining flock uniformity.

A well-graded flock is bound to be more predictable, easier to manage, and more profitable. Combine this with the extensive features that seasoned poultry management software offers, and farm owners will start managing a flock with much greater production potential.

India is one of the fastest growing countries in terms of population, economy, infrastructure, information technology and other segments, yet grappling with persistent challenges like poverty, malnutrition, and nutritional insecurity. Among these, protein malnutrition is a silent crisis affecting millions. Despite being the world’s second-most populous country, over 80% of Indians fail to meet their daily protein requirements. While 75% of the population identifies as non-vegetarian, most consume meat only occasionally—on weekends, festivals, or special occasions. A survey by IMRB revealed that 73% of Indians are protein deficient, and a staggering 93% are unaware of their daily protein needs.

The misconception that protein is essential only for bodybuilders and athletes has left the general population unaware of its fundamental role in overall health. This lack of awareness has far-reaching consequences for individuals and the nation.

How Serious Is Protein Malnutrition in India?
Protein-energy malnutrition (PEM) is a significant public health issue in India, with devastating effects on children and adults alike:
– Global Hunger Index: India ranks 101 out of 116 countries.
– Undernourished Population: India has the highest number of undernourished people globally.
– Child Malnutrition: 35% of children under five are malnourished, and 48% suffer from stunted growth.
– Infant Mortality: 33 of every 1,000 children born in India die before their first birthday.
– Anaemia: 68% of children and 66% of women are anaemic.
– Protein Deficiency: 73% of Indians lack adequate protein intake.

Double Burden: Alongside malnutrition, obesity and non-communicable diseases like diabetes and heart disease are rising due to poor dietary habits.

How Much Protein Are Indians Eating?
The Indian Council of Medical Research (ICMR) recommends 0.8 to 1 gram of protein per kilogram of body weight daily, but the average Indian consumes only 0.6 grams per kilogram. Globally, average protein consumption stands at 68 grams per day, while India lags behind at 47 grams per day.

A survey across 16 Indian cities found that 85% of people believe protein causes weight gain, highlighting the widespread misinformation. Moreover, cereals, which are poor protein sources, dominate Indian diets, contributing 60% of protein intake. Pulses, legumes, meat, and poultry, the richer sources of protein, account for only 11% of dietary energy.

Protein deficiency

Why Are Indians Protein Deficient?
Several factors contribute to protein deficiency in India:
1. Cereal-Dominant Diets: Poor digestibility and incomplete amino acid profiles of cereals make them inadequate protein sources.
2. Shift in Food Habits: Increased consumption of fast foods and processed foods has reduced dietary quality.
3. Poverty and Food Insecurity: Many families cannot afford protein-rich foods.
4. Social Misconceptions: Myths about certain food categories lead to reduced protein intake.
5. Lack of Awareness: Misinformation and myths, especially among women who are key decision-makers in household nutrition, exacerbate the problem.
6. Inadequate Infant Feeding Practices: Poor early nutrition has lifelong consequences.

The Impact of Protein Deficiency
Protein is vital for growth, development, immunity, and repair. Its deficiency has severe consequences:
– For Children: Stunted growth, poor cognitive development, and reduced school performance.
– For Adults: Loss of muscle mass, impaired metabolism, and increased susceptibility to illnesses.
– For the Economy: Reduced productivity, poorer educational outcomes, and long-term economic losses.

How to Mitigate Protein Malnutrition in India
The Indian government has launched programs like the Public Distribution System (PDS), Integrated Child Development Services (ICDS), and mid-day meals. However, these largely focus on cereals. To combat protein malnutrition effectively, we need:
1. Increased Awareness: Massive campaigns to educate the public on protein’s importance and daily requirements.
2. Inclusion of Protein-Rich Foods: Adding affordable protein sources like eggs, milk, and chicken to government nutrition programs like mid-day meal in schools
3. Affordable Protein: Subsidizing protein-rich foods to make them accessible to all.
4. Dietary Education: Promoting balanced diets that include pulses, legumes, and animal proteins.
5. Focused Intervention: Prioritizing nutrition in the first 1,000 days of life, from conception to a child’s second birthday.

How Eggs and Chicken Can Help
Eggs and chicken are among the most affordable and accessible protein sources, offering immense potential to combat malnutrition:
1. Abundance: India is the world’s third-largest egg producer and fourth-largest chicken producer.
2. Complete Protein: These are high-quality protein sources containing essential amino acids not found in many plant-based foods.
3. Nutritional Powerhouses: Eggs are rich in vitamins, minerals, and good fats, while chicken supports muscle strength, immunity, and stress relief.
4. Versatility and Affordability: Easy to prepare, eggs and chicken can fit into any meal plan.

Need for Collective Action
To overcome protein malnutrition, we must act together. Poultry producers, government agencies, social influencers, medical practitioners, and organizations like NECC, Vets in Poultry, PFI, CLFMA, INFAH, IPEMA, ICMR, IMA and NIN must join hands. By promoting chicken and eggs through awareness campaigns, partnerships with health organizations, and inclusion in nutrition programs, we can:
– Educate Consumers: Bust myths and promote protein-rich diets.
– Drive Demand: Inspire families to make eggs and chicken regular dietary staples.
– Strengthen Programs: Enhance government initiatives with animal protein sources.

Fighting protein malnutrition is not just a health issue; it is a mission to secure India’s future. Let’s ensure every child has the opportunity to grow, thrive, and contribute to a healthier, stronger nation. Together, we can make protein malnutrition a challenge of the past.

Introduction
The poultry industry has seen exponential growth over the last few decades, driven by the demand for high-quality protein sources such as chicken. However, the intensification of poultry production has also brought challenges, particularly in managing the health of broilers, which are reared under conditions that can predispose them to stress and diseases. Among these, gut health is a critical area of focus because it directly influences the overall health, performance, and productivity of the birds.

Traditionally, antibiotics have been used extensively to manage gut health issues and prevent diseases. However, the rise of antimicrobial resistance (AMR) and global consumer demand for antibiotic-free poultry has necessitated a shift toward non-antibiotic solutions. Phytomolecules, bioactive compounds derived from plants, have emerged as a promising alternative for maintaining gut health in broilers. This article delves into the significance of gut health in broilers, explores the role of phytomolecules and highlights their effectiveness as a sustainable solution in modern poultry operations.

Understanding Gut Health in Broilers
Gut health refers to the optimal functioning of the gastrointestinal (GI) tract, which is essential for nutrient absorption, immune response, and overall well-being of broilers. In poultry, the gut is not only responsible for digestion but also acts as a key barrier against pathogens, playing a critical role in the immune system. (Image 1)

A healthy gut consists of a balanced microbial population (microbiota), an intact intestinal barrier, and a well-regulated immune response. Any imbalance in these components can lead to gut dysfunction, manifesting as poor nutrient absorption, diarrhoea, increased susceptibility to infections, and reduced growth performance.

Common gut health challenges in broilers include:
1. Dysbiosis: An imbalance in the gut microbiota, often caused by stress, poor nutrition, or infections, can disrupt gut function.
2. Enteric diseases: Diseases like necrotic enteritis (caused by Clostridium perfringens) and coccidiosis (caused by Eimeria species) can severely damage the intestinal lining.
3. Leaky gut syndrome: Increased intestinal permeability can allow harmful substances to pass into the bloodstream, triggering inflammation and immune responses.
4. Poor nutrient absorption: Impaired gut function can reduce the efficiency of nutrient absorption, affecting growth rates and feed conversion ratios.

Source: Self Field observations

Maintaining optimal gut health is, therefore, essential to achieving high productivity, reducing mortality, and ensuring efficient feed utilization in broilers.

The Role of Phytomolecules in Gut Health
Phytomolecules are bioactive compounds derived from plants, including essential oils, alkaloids, flavonoids, tannins, and terpenes. These molecules possess a wide range of biological activities, such as antimicrobial, antioxidant, anti-inflammatory, and immunomodulatory properties, making them effective in maintaining and improving gut health.

Over the years, research has demonstrated the potential of phytomolecules to support gut health in poultry. Several studies have shown that these plant-derived compounds can modulate the gut microbiota, strengthen the intestinal barrier, and enhance immune responses, thus promoting better growth and health in broilers.

1. Antimicrobial Properties
One of the primary benefits of phytomolecules is their ability to exert antimicrobial effects. Many essential oils and plant extracts contain compounds like carvacrol, thymol, and eugenol, which have been found to inhibit the growth of pathogenic bacteria such as Escherichia coli, Salmonella, and Clostridium perfringens. These antimicrobial properties help maintain a balanced gut microbiota, reducing the risk of infections and dysbiosis. (Image 2)

A study by Burt (2004) demonstrated that essential oils containing carvacrol and thymol are effective in inhibiting the growth of Salmonella and Campylobacter in broilers. Similarly, Liu et al. (2012) found that phytogenic compounds such as oregano and thyme oils can significantly reduce the colonization of pathogenic bacteria in the poultry gut.

2. Antioxidant Effects
Oxidative stress is a common challenge in modern poultry production, especially under intensive farming conditions. Excessive oxidative stress can damage the intestinal lining, leading to inflammation and compromised gut integrity. Phytomolecules such as flavonoids and phenolic acids have strong antioxidant properties, which help neutralize free radicals and protect the intestinal cells from oxidative damage. (Image 3)

Flavonoids, such as quercetin and catechins, have been shown to enhance the activity of antioxidant enzymes, reduce inflammation, and promote gut integrity. In a study conducted by Rehman et al. (2020), supplementation with flavonoid-rich plant extracts improved the gut health of broilers by reducing oxidative stress and enhancing the intestinal barrier function.

3. Anti-inflammatory Action
Chronic inflammation in the gut can lead to poor nutrient absorption, tissue damage, and increased susceptibility to infections. Phytomolecules possess anti-inflammatory properties that can mitigate gut inflammation and support tissue repair. Compounds such as curcumin (found in turmeric) and gingerols (found in ginger) are well-known for their anti-inflammatory effects. A study by Khaleel et al. (2021) demonstrated that dietary supplementation with curcumin significantly reduced gut inflammation in broilers and improved their overall performance. Similarly, ginger extract has been found to decrease pro-inflammatory cytokines and enhance gut health in poultry.

4. Enhancing the Intestinal Barrier
The intestinal barrier is the first line of defence against harmful pathogens and toxins. Phytomolecules, particularly tannins and essential oils, can strengthen the intestinal lining by promoting the production of tight junction proteins that seal the spaces between intestinal cells. This helps reduce intestinal permeability (leaky gut) and prevents the translocation of harmful substances into the bloodstream. (Image 4)

In a study by Yang et al. (2015), tannin-rich plant extracts were found to enhance the expression of tight junction proteins in the intestinal mucosa of broilers, resulting in improved gut integrity and reduced incidence of leaky gut.

5. Modulating the Gut Microbiota
Phytomolecules have prebiotic effects that promote the growth of beneficial gut bacteria, such as Lactobacillus and Bifidobacterium, while inhibiting pathogenic bacteria. A balanced gut microbiota plays a crucial role in maintaining gut health by enhancing nutrient absorption, stimulating the immune system, and protecting against infections.

Research by Windisch et al. (2008) found that phytogenic feed additives, including essential oils and polyphenols, can modulate the gut microbiota by promoting beneficial bacteria and reducing pathogenic bacterial populations. This microbiota modulation helps maintain gut homeostasis, which is essential for optimal growth and performance in broilers.

Phytomolecules in Commercial Broiler Production
The use of phytomolecules as feed additives in broiler production is gaining popularity as a natural and effective alternative to antibiotics. Various commercial phytogenic products containing essential oils, plant extracts, and other bioactive compounds are now available for use in poultry diets.

Benefits of Phytomolecules Supplementation
1. Improved Growth Performance: Several studies have shown that phytomolecules supplementation can enhance growth rates, feed conversion ratios, and overall performance in broilers. For example, Yang et al. (2015) reported that broilers supplemented with a blend of essential oils and polyphenols exhibited higher weight gain and better feed efficiency.

2. Reduced Mortality and Morbidity: By promoting gut health and enhancing the immune system, phytomolecules help reduce the incidence of enteric diseases and lower mortality rates in broilers. A study by Ciftci et al. (2010) found that broilers fed with a diet containing thyme and rosemary essential oils had a lower incidence of necrotic enteritis and improved survival rates.

3. Enhanced Feed Efficiency: Phytomolecules improve nutrient absorption by maintaining gut integrity and supporting the activity of digestive enzymes. This leads to better feed efficiency and reduced feed costs, which are critical factors in commercial broiler production.

4. Sustainability and Consumer Acceptance: The use of phytogenic feed additives aligns with the growing consumer demand for antibiotic-free poultry products. As these additives are derived from natural sources, they are perceived as safe and environmentally friendly, contributing to the sustainability of poultry production.

Challenges and Considerations
While the benefits of phytomolecules in poultry production are well-documented, there are some challenges associated with their use.
These include:

– Variability in Efficacy: The efficacy of phytomolecules can vary depending on factors such as plant source, extraction method, dosage, and the overall diet composition. Standardization of phytogenic products is essential to ensure consistent results.

– Cost: Phytogenic feed additives can be more expensive than traditional antibiotics. However, the long-term benefits, including improved bird health and performance, can offset the higher initial costs.

– Regulatory Approval: Globally in some regions, the use of certain phytomolecules in animal feed may be subject to regulatory approval. Producers should ensure that the phytogenic products they use comply with local regulations.

Conclusion
Gut health is a cornerstone of successful broiler production, influencing not only the health and welfare of the birds but also their growth performance and profitability. As the poultry industry continues to shift toward antibiotic-free production systems, phytomolecules offer a natural and effective solution for maintaining gut health in broilers.
By leveraging the antimicrobial, antioxidant, anti-inflammatory, and microbiota-modulating properties of phytomolecules, poultry producers can improve gut integrity, reduce the incidence of enteric diseases, and enhance the overall performance of their birds.

Science is a novel practise to allow potential of ingredients or elements. It will be very helpful when it meets your requirements So well said that Learning by Doing Science…Plant bioactive compounds, such as phytochemicals, in poultry diets, are gaining popularity due to their potential antioxidant and anti-microbial activities. Phytogenic feed additives (PFAs) have emerged as natural alternatives to antibiotic growth promotors and have great potential in the poultry industry. In recent years, cinnamon (one of the most widely used spices) has attracted attention from researchers as a natural product with numerous health benefits for poultry. The essential oils in cinnamon, in particular, are of interest because of their antioxidant, anti-microbial, anti-inflammatory, antifungal, and hypocholesterolaemic effects, in addition to their ability to stimulate digestive enzymes in the gut.

Know Values of Poultry Industries
India Poultry Feed Market was valued at USD 3.27 billion in 2024 and is anticipated to project impressive growth in the forecast period with a CAGR of 6.21% through 2030.17 Sept 2024The demand for poultry feed is expected to increase due to the country’s growing poultry production, the expanding retail and food service industry, and advancements in poultry breeding techniques. However, high feed costs may put downward pressure on demand.

CINNAMALDEHYDE
Cinnamon belongs to the genus Cinnamomum (Lauraceae family) which contains more than 250–300 aromatic evergreen shrubs and plant trees However, only a few of these species have significant economic importance worldwide as a common spice including Cinnamomum zeylanicum (C. zeylanicum: True Sri Lankan cinnamon), C. cassia (Chinese cinnamon), C. burmanni (Indonesian cinnamon) and C. loureiori (Vietnamese cinnamon). The annual production of cinnamon is around 0.23 million metric tons, mainly cultivated in Indonesia, Sri Lanka, China, India, Vietnam, and Madagascar.

Phytochemistry Of Cinnamaldehyde
Phytochemicals are plant bioactive non-nutritive compounds that are usually found in small quantities They have different classes according to their structure and include phenolic compounds, phytosterols, phytoestrogens, glucosinolates, saponins, terpenoids, protease inhibitors and organo-sulfur containing compounds. They have significant antioxidant capacity to reduce and protect oxidative stress. Cinnamon consists of various bioactive compounds. Modern analytical techniques have enabled the characterization, identification, purification and quantification of individual compounds and the study of their potent biological activities. Generally, gas chromatography is applied to characterize volatile compounds while liquid chromatography for the identification of phenolic compounds. It is documented that cinnamon consists of natural antioxidant, anti-microbial and anti-inflammatory components such as volatile oils, flavonoids, curcuminoids, coumarins, tannins, alkaloids, xanthones, terpenoids, phenolics and other compounds in significant amounts. The concentration of volatile compounds in cinnamon essential oil (CNO) mainly depends upon the plant parts (leaves, bark, root, stem) from which it is extracted. About forty-one volatile compounds were identified from the bark oil of cinnamon (C. cassia) tree. Cinnamaldehyde (55% to 78%) is the main flavor compound in CNO extracted from bark while eugenol (59–78%) is the main compound in CNO that is extracted from leaves. The volatile oil is approximately 0.6–1% and 1–2% phlobatannins, calcium oxalate, starch, mucilage, and mannitol (sweet) in the bark. Moreover, Kim, et al. further investigated the cinnamon bark oil through GC-MS (gas chromatography– mass spectrometry) and identified seventeen different bioactive compounds. The major bioactive compounds of cinnamon are cinnamaldehyde, cinnamate, cinnamic acid, all of which play vital roles in various biological activities. The different essential oils that have been reported in cinnamon include trans-cinnamaldehyde, eugenol, cinnamyl acetate, L-borneol, L-bornyl acetate, β-caryophyllene, caryophyllene oxide, E-nerolidol, α-thujene, α-cubebene, terpinolene and α-terpine [19]. The LC-MS (liquid chromatography–mass spectrometry) analysis has shown that the concentrations of condensed tannins, proanthocyanidins (PAs) and epicatechin in cinnamon are 26.8%, 23.2% and 3.6%, respectively. Cinnamon has a high polyphenol content and the anthocyanidins (A and B procyanidins) are also present in cinnamon

Poultry Gut Health
Efficient immune system development and proper digestion and absorption of feed, water, and electrolyte balance in the gut leads to the development of strong gut health in poultry. The gut ecosystem plays a vital role in eliminating toxins and infectious agents from the intestinal tract of the poultry. Many factors influence the gut microbial ecosystem, including feed additives (phytobiotics, prebiotics, probiotics, feed enzymes, organic acids etc.), feed composition, genetics, heat stress, feeding practices on the poultry farm, among others. These factors exert a substantial impact on the gut microbiota and poultry health. The association between gut health and poultry performance is widely accepted with optimal health including proper physiological functions of the intestinal tract, morphological integrity, efficient immune response, developed barrier functions, energy balance, tissue metabolism, sustained inflammatory balance and sufficient microbiota to perform desired functions in the gut. The health of poultry is influenced by the structure and functionality of gut microbiota. The progression of acquisition and maturation of the intestinal microbiota throughout the growth period of the poultry has a marked impact on the modulation of physiological functions (nutrient digestion, immunity, intestinal barrier integrity etc.) to maintain gut homeostasis and development of the intestinal epithelium. These functions are essential to optimize energy use and efficiency of extraction by the poultry birds.

Impact of Cinnamon on the Digestibility of Nutrients
Improved utilization of feed improves the feed conversion ratio (FCR), body weight gain (BWG) and overall health performance of broiler chicken. The stabilization of the gut microbiota ecosystem and the stimulation of digestive enzymes secretion are the two well-accepted mechanisms that play a leading role in improving feed utilization and inhibiting the growth-depressing ailments related to metabolism and digestion. The potential impacts of CNO on the secretion of digestive enzymes from the intestinal mucosa and pancreas have been described in many poultry studies. These positive impacts had been confirmed to improve the digestibility of nutrients. Additionally, the bioactive compounds of cinnamon affect lipid metabolism by transporting the fatty acids in the digestive tract of broilers. The CNO has positive effects on the secretion of digestive enzymes and improves the digestibility of nutrients in the gut.

Supplementation of CNO in broilers diet increased the villus height (VH) in the duodenum and jejunum with associated increased villus surface area and the efficiency of absorption and digestion of nutrients. In addition, a greater VH means greater mucosal digestive enzyme activity, which ultimately improves the digestibility of nutrients.
To sum up, the use of cinnamon and its bioactive compounds as feed additives in poultry diets have potent effects on antioxidant status, immunity, nutrients availability and digestibility, enzymes secretion, mucus production, gut microbiota and overall poultry health, growth performance and productivity

Introduction
The poultry industry makes significant contributions to our economy. It was the first livestock sector to industrialize. India is currently the third-largest producer of eggs (122 billion eggs) and the fifth-largest producer of chicken (4.4 MMT) (Gulati and Juneja, 2023). In the early days of the poultry business, the various stages and components, like feed manufacturers, hatcheries, grow-out farms, processing plants, and logistics, were functioning independently in markets while depending on each other to sell their products or services. Eventually, these related businesses within the poultry industry began to integrate and function as a single system. Vertically integrated poultry farming is a comprehensive approach that unifies all stages of poultry production (breeding, hatching, feed production, farming, processing, and distribution) under one umbrella.

Figure 1. Schematic representation showing typical operation of a vertically integrated poultry system+

Figure 1 shows the typical operation of a vertically integrated poultry farm and processing unit. The vertical integration model, which incorporated large industry players and small farmers through a contract farming approach, emerged in the middle of the 20th century. This type of contract approach catalyzed the sudden growth of the poultry industry. Integrating different stages of poultry production through strong and modern processes and technologies promotes sustainability, affordability, and economic growth while ensuring quality throughout the supply chain. Streamlining every stage of the supply chain, fostering innovations and technologies, and reducing reliance on external suppliers are the key components of a successful vertically integrated poultry farming system. This article discusses the significance and potential of vertical farming in providing high-quality animal protein at affordable prices to meet the increasing demand for protein sources without compromising sustainable production practices.

Promoting Ethical Standards
Promoting ethical standards in a vertically integrated poultry system is crucial for humane and eco-friendly practices. Adopting and maintaining ethical standards entails supervising each phase of production, from breeding to processing, to assure compliance with improved welfare standards. Humane treatment covers sufficient space, appropriate feed, and healthcare for chickens. Specifically, in the vertically integrated poultry business, large organizations are instrumental in various levels of interconnected activities. With corporations’ business-oriented approach, the rearing conditions of poultry at breeder farms and commercial farms will be more sophisticated, ensuring humane and environmentally friendly practices. In addition, these corporations adopt ethical standards as promotional tools for selling their processed products. Here, cage rearing of birds shifted to floor-rearing practices, keeping poultry birds in more spacious ground areas rather than in cages. This practice provides the birds ample space to express their behavioral needs, like stretching wings, foraging, dust bathing, and ample time to move around. This shift in rearing space improves the birds’ health. It reduces their stress, increasing the productivity of good-quality meat and eggs  . Maintaining bird density following European Union norms (33 kg broilers/m2) or Bureau of Indian Standards (floor space allocation, 0.3 to 1.0/square feet) reduces the risk of overcrowding and ensures the welfare of birds (Giersberg, Hartung et al. 2016).

Furthermore, ensuring ample feed and water availability at all points in a poultry system is critical for maintaining the birds’ optimal health, growth, and productivity. According to standards set by organizations such as the National Research Council (NRC) and the World Organization for Animal Health (WOAH), poultry feed should be balanced with the necessary nutrients. The diet typically contains 18-20% crude protein for broilers during the starter phase (0-3 weeks) and 16-18% during the grower phase (4-6 weeks).
Additionally, the quantity of feed provided differs according to the age and type of rearing. It is observed that during the initial six weeks of the rearing period, broiler chickens typically consume around 1.8-2.2 kg of feed, while layers consume about 110-120 grams of feed per day once they begin laying (Pal, Prakash et al. 2020). Importantly, feed should be stored properly to ensure that it is free from contaminants and toxins, particularly mycotoxins, which are secondary metabolites produced by fungi, and can be detrimental to poultry health. Additionally, a vertically integrated poultry system ensures residue-free and microbiologically safe meat by adopting stringent prophylactic and therapeutic measures at both breeding centers and farm units. Also, regular biosecurity protocols, such as footbaths, controlled access to facilities, and stringent sanitation practices, are essential to prevent pathogen introduction and spread. Besides, it is crucial to provide nest boxes for natural egg laying in breeder rearing to maximize egg production and ensure the well-being of the birds. Nest boxes provide a regulated setting that promotes hygienic and secure egg laying, enhancing the quality of eggs and their potential to hatch successfully. Nest boxes must be at least 12 x 12 inches per hen and should be placed at a suitable height to prevent floor laying (Graham 2024). These boxes for laying eggs relieve stress, encourage innate instincts, and simplify the process of harvesting eggs. In addition, they enhance egg cleanliness and enable more effective health monitoring, hence increasing productivity and adhering to humane standards. Collectively, adoption of above-mentioned standards/measured ensure the health and productivity of chickens and pay way for the sustainable and ethical farming practices.

Streamlining Resource Allocation
Optimizing resource allocation in a vertically integrated poultry system improves operational efficiency, lowers expenditures, and enhances productivity.
The adoption of this system maximizes resource allocation by optimizing the utilization of feed, water, and energy, hence decreasing wastage. Centralized planning and a coordinated supply chain are integral parts of a vertically integrated poultry business. These allow better forecasting and a seamless flow of materials into and from the system, reducing bottlenecks and delays in delivery. Further, integration ensures efficient utilization of floor space in rearing units, by optimizing designs of poultry houses and layouts, while adhering to animal welfare guidelines. Feed management (nutritious feed in the right quantity at the right time) using advanced automated feeding systems with appropriate designs reduces feed waste and improves the feed conversion ratio (FCR). Furthermore, waste products from one stage of production can be repurposed for another use (byproduct utilization). Generation of biogas and fertilizer from poultry litter and animal feed ingredients (meat and bone meal) from all non-edible poultry offal from slaughter plants can be well utilized to reduce waste and create additional revenue streams. For instance, eggshells can be processed into calcium supplements for animal feed or as soil conditioners (Gul, Shoqer et al. 2024) , dead chicks and birds may be converted into protein meal for animal feed, or biogas can be produced using strict biosecurity protocols. Interesting, innovative practices such as in-ovo sexing can reduce the number of male chicks hatched, and those that are hatched can be used in feed production or other industries (Jia, Li et al. 2023). Appropriate treatment of effluents from poultry operations using advanced wastewater systems, and water recycling are inevitable in vertically integrated poultry firms.

Further, during chicken processing, sludge can be processed into organic manure, providing a valuable agricultural resource, and reducing waste disposal issues. Moreover, transitioning from water-based chilling systems to air-based ones considerably lowers water use. Air chilling preserves meat quality by minimizing the uptake of water. Previous reports suggests that air chilling potentially delay the dominance of spoilage organisms Pseudomonas spp as it pays way for diverse microbiome (Belk, Duarte et al. 2021). Additionally, implementing water-saving technologies and practices such as high-pressure, low-volume cleaning systems reduces the use of water resources in vertically integrated poultry farming. Besides, incorporating water-saving technology and techniques, such as high-pressure, low-volume cleaning systems, decreases the use of water resources during chicken processing. Thus, integrated systems push for energy-efficient technologies and invest heavily in securing those technologies, which reduce overall energy consumption. For example, radiant heaters, which deliver direct heat to birds, and Heat recovery systems that capture and reuse waste heat from ventilation, reducing the unit’s energy needs. Also, rooftop solar panels provide a renewable energy source, decreasing reliance on non-renewable electricity. Also, automated feeding and drinking systems ensure precise feed and water delivery, reducing waste and energy consumption. Next, the utilization of centralized collected data, predictive analyses, and internet technologies facilitates data-driven decision-making, hence enhancing the business intelligence of a vertically integrated business model. The utilization of centralized collected data, predictive analyses, and internet technologies facilitates data-driven decision-making, hence enhancing the business intelligence of a vertically integrated business model. In addition, staff skill upgradation and education play a critical role in sustainable farming and production. Thus, educating staff on proper bird, product handling, and hygiene improves resource efficiency. Additionally, bulk purchasing, shared infrastructure, quality standards, traceability, and sustainability initiatives lower capital and revenue costs. Therefore, the adoption and upgradation of energy efficient technologies, data-driven decision-making, and waste management contribute to more eco-friendly and cost-effective poultry operations.

Delivering production efficiency and nutritional excellence
Vertical integration in poultry farming and processing promotes the production of superior animal protein that is accessible to consumers at reasonable prices. Here, the approach greatly reduces the life cycle of chicken products, reducing the time from breeding to market-ready chicken. This acceleration is essential for satisfying consumer demand, maintaining a steady supply, and preserving product freshness. Basically, it facilitates efficient resource management, shortens the life cycle of poultry, reduces overhead charges, achieves economies of scale, ensures consistent quality control, enables the adoption of new technologies and processes, and streamlines the distribution channels. This approach controls all stages of production, where it reduces bottlenecks and the wastage of resources like feed, water, and energy. Also, its centralized planning, efficient operations, and the procurement of inputs in large quantities result in reduced production costs, enabling the protein to be offered to customers at a more affordable price. For instance, vertical integration ensures that chickens reach market weight more quickly, typically within 35 to 42 days, compared to longer periods in less integrated operations (Wilcox, Sandilands et al. 2024) . Also, FCR can be improved to as low as 1.5 to 1.7 (Gulati and Juneja 2023 . Further, organizations with vertical integration can efficiently process up to 13,000 birds/hour. This efficient processing capability guarantees that chickens are slaughtered and processed promptly upon reaching their optimal weight, decreasing the time it takes them to go from the farm to the table. This type of shorter life cycle allows for more frequent production cycles and faster response to market demand. Moreover, the vertically integrated approach is defined by large-scale operations, which allows it to take advantage of economies of scale, reducing the cost per unit of production. This comprises reductions in expenses related to feed, equipment, labor, and other associated costs. Besides, it eliminates the obstacles of multilevel middlemen and assists in streamlining logistics (Begum 2005, Bamiro and Shittu 2009).

Nutritionally, poultry products are rich in high-quality proteins with fewer calories than red meat products. They contain essential vitamins like A, D, E, K, C, and B and minerals such as iron, calcium, magnesium, zinc, potassium, and Selenium. These nutrients are readily absorbed by the body, enhancing the nutritional value of the poultry products. Proteins in chicken products are easily digestible animal protein compared to other livestock proteins. It contributes to muscle growth and overall health in humans. Vertical integrated companies maintain consistency in their products by overseeing breeding, feeding, processing, and distribution, thus increasing consumer trust and satisfaction. Moreover, precision nutrition by adequate feed formulation based on the specific needs of poultry at different growth stages and environmental conditions enhances feed efficiency, reduces waste, and ensures products are rich with nutrients. Vertically integrated firms effectively oversee their existing distribution networks, allowing direct delivery to a large number of retailers and direct customers. Comprehensive supply chain management minimizes distribution expenses, lowers the price increases linked to middlemen, assures a consistent flow of products, and improves the effectiveness and dependability of the supply chain. Therefore, implementing vertical integration within an existing business offers chicken products of exceptional quality at competitive prices.

Catalyst for local economic development, job opportunities and investment
The poultry industry began evolving in the 1930s and adopted a vertically integrated style of contract farming in the 1950s. Later in the 1980s, horizontal integrations were introduced, resulting in regional monopsonies in the poultry business (Constance, Francisco et al. 2013) . However, by integrating the different stages of production, the integrators reduced costs by coordinating the production capacity of each stage or component of the production system. The chicken industry has grown to a higher magnitude today by combining production stages into large vertically integrated firms that can take advantage of rapidly changing technologies and innovations. Generally, vertical integration involves contract farming or breeding, where large organizations contract local farmers to breed/raise chickens, providing them with chicks, feed, veterinary support, and technical guidance. This system creates a stable income source for farmers, who benefit from reduced market risk and guaranteed prices for their produce. By reducing the need for farmers to invest in costly infrastructure, such as feed mills or processing plants, vertical integration makes poultry farming more accessible and profitable for local communities. In India, 70% of poultry farmers engaged through contract farming are small farmers with a flock size of 3,000-10,000 birds; 20% are medium-scale farmers with 10,000- 50,000 birds, and only 10% are large-scale farmers with 50,000-400,000 birds (Khire and Ryba 2024). Additionally, the presence of vertically integrated poultry companies stimulates local economies through job creation. These companies require a workforce for hatcheries, feed mills, processing plants, and distribution networks, creating employment opportunities beyond the farm level. Investment in local infrastructure, such as roads and utilities, often accompanies these operations, further benefiting the community. This significantly increases the cash flows to rural areas. This provides a stable and profitable source of income within their communities, where individuals can maintain their agricultural heritage while incorporating poultry farming. This dual income stream enhances financial stability for rural families, encourages the retention of agricultural knowledge, and sustains the social fabric of rural areas. The poultry industry is characterized by shorter cash flow cycles, ensuring farmers receive timely payments. This reliable income stream supports the day-to-day financial needs of rural families, enhancing their quality of life and enabling them to invest in education, healthcare, and other essential services. Income predictability also allows for better financial planning and reduces economic uncertainty for rural households. Additionally, jobs in transportation and logistics, further boost the rural economy. Other support services such as laboratories, workshops, warehouses, professional training, and other ancillary services create a diverse range of jobs in rural areas. Thus, vertical integration in poultry farming and processing significantly enhances the economic resilience and prosperity of rural areas.

The concept of sustainability in a vertically integrated poultry business is regarded as multi-dimensional. The term sustainability encompasses economic, environmental, social, and institutional governance aspects  . The output of sustainable production is maximizing the delivery of safe and nutritious food per unit of input resource without increasing pressure on land  . Implementing energy-efficient technologies and practices at every production stage reduces overall energy consumption. For example, LED lighting, energy-efficient ventilation systems, and high-efficiency heating systems can lower the energy required for poultry housing and processing. Renewable energy sources, such as solar energy, wind energy, biogas, etc., can provide a significant portion of the energy required in the poultry industry. Installing solar panels on farm buildings and processing facilities, installing wind turbines to generate electricity for farm operations (in areas with consistent wind patterns), and utilizing agricultural by-products and waste materials as fuel for boilers and heating systems reduces waste and reliance on conventional fossil fuels. Apart from these, space utilization is optimized by setting up advanced housing systems, including multi-tiered aviaries. These systems enable the housing of a greater number of birds in a single location without compromising animal welfare, thereby reducing the overall land footprint of poultry operations. On the other hand, adoption of nipple drinker system reduces water wastage by preventing spillage and evaporation. Additionally, the transition from immersion to air chilling during refining enhances energy efficiency and reduces water consumption. Additionally, air chilling offsets the risk of cross-contamination and improves the quality of the final product by preserving a more natural flavor and texture. Similarly, vertical integration involves adopting water reclamation systems to decrease water consumption and heat recovery systems that harvest waste heat produced during processing and redeploy it to heat water and power equipment or maintain facility temperatures. Together, these practices in vertically integrated units reflect the organization’s commitment to environmental stewardship while maintaining high productivity and economic sustainability (Figure 2).

Figure 2. Schematic representation of sustainable practices employed in vertically integrated poultry farms and processing units. The figure highlights solar and wind energy use to meet energy needs across poultry farms, breeding units, hatcheries, and processing plants. Litter from poultry farms is converted into bioenergy and byproducts like manure, feather meal, and meat and bone meal, reducing environmental pollution. In processing, sludge is managed through organic composting, biogas production, and animal feed creation. Water management includes using nipple drinker systems and water reclamation, while energy-efficient processing methods like shifting from immersion to air chilling and introducing HVAC systems are employed to conserve energy and water resources.

Conclusion
In conclusion, implementing a vertically integrated poultry business model offers a sustainable, efficient, and cost-effective strategy for producing high-quality animal protein and products according to consumer preferences. This strategy involves centralized control over all phases of poultry production, from breeding and raising birds to processing and packaging the final products. By maintaining oversight at every step, companies can ensure that resources such as energy, water, and feed are used efficiently, minimizing waste throughout the production chain. Moreover, it integrates ethical practices and ecologically sustainable methods into production. Ethical practices include providing humane living conditions for the birds, such as adequate space, proper nutrition, and veterinary care, which collectively enhance animal welfare. Sustainable practices involve reducing the carbon footprint by using renewable energy sources like solar and wind power and recycling waste products into bioenergy or organic fertilizers. By focusing on these ethical and sustainable procedures, the poultry sector improves the overall health and well-being of the animals and enhances the quality of the products. Consumers receive higher-quality poultry products that are produced in an environmentally responsible manner, supporting both animal welfare and the health of the planet.
