Weather fluctuations, particularly during seasonal transitions, create significant stress in poultry production systems. Sudden changes in temperature, humidity, ventilation patterns, and air quality weaken the birds’ immune defenses and predispose them to respiratory infections. Among these, Mycoplasmosis is one of the most economically important diseases affecting both commercial layers and breeder flocks.

The two major pathogenic species affecting poultry are:
– Mycoplasma gallisepticum infection (MG)
– Mycoplasma synoviae infection (MS)
These organisms are highly contagious and often become more problematic during changing weather conditions due to increased environmental stress and compromised flock immunity.

Why Changing Weather Increases Mycoplasma Problems
During weather transitions such as:
– Summer to monsoon
– Monsoon to winter
– Sudden cold or heat waves
birds experience physiological stress that suppresses their immune response. Several environmental factors contribute to Mycoplasma outbreaks:
1. Temperature Fluctuation
Rapid day-night temperature variation stresses birds and damages the respiratory mucosa, making it easier for Mycoplasma organisms to colonize the respiratory tract.
2. Poor Ventilation
Farmers often reduce ventilation during cold weather to conserve heat. This increases:
– Ammonia levels
– Dust accumulation
– Humidity
– Carbon dioxide concentration
Such conditions irritate the respiratory tract and favor Mycoplasma multiplication.
3. High Humidity and Wet Litter
During monsoon seasons, excessive moisture increases pathogen survival and worsens respiratory stress.
4. Secondary Infections
Changing weather also favors bacterial and viral co-infections such as:
– Newcastle disease
– Infectious bronchitis
– Escherichia coli infection

These infections intensify the severity of Mycoplasma disease.
Clinical Signs in Layers and Breeders
Affected birds may show:
– Coughing and sneezing
– Nasal discharge
– Rales and respiratory sounds
– Swollen sinuses
– Watery eyes
– Reduced feed intake
– Depression and poor growth
– Increased mortality in severe cases

In breeder flocks, fertility and hatchability may decline significantly.

Impact on Layer Performance
Mycoplasma infection severely affects commercial egg production.
1. Drop in Egg Production
Layers infected with MG or MS commonly show:
-Sudden reduction in egg production
– Irregular laying patterns
– Delayed peak production
Production losses may range from 5–20% depending on flock condition and secondary infections.
2. Poor Egg Quality
Infected layers may produce:
– Thin-shelled eggs
– Misshapen eggs
– Smaller eggs
– Poor shell strength
This increases breakage and market rejection.
3. Increased Feed Conversion Ratio (FCR)
Respiratory stress reduces feed efficiency, increasing production cost per egg.
4. Increased Culling and Mortality
Chronically affected birds become poor performers and require early culling.

Impact on Breeder Performance
The economic effect of Mycoplasma is even more serious in breeder operations.
1. Reduced Fertility
Mycoplasma infection negatively affects reproductive performance, lowering fertility percentage.
2. Poor Hatchability
Vertical transmission through eggs can infect embryos, causing:
– Embryonic mortality
– Weak chicks
– Poor hatchability
3. Transmission to Progeny
MG and MS can spread from infected breeders to chicks through eggs, creating long-term farm problems.
4. Reduced Chick Quality
Chicks from infected breeder flocks often show:
– Weakness
– Respiratory distress
– Poor growth potential
– Higher early mortality

Economic Losses
Mycoplasma outbreaks during changing weather can lead to major financial losses through:
– Reduced egg production
– Poor hatchability
– Increased medication costs
– Mortality and culling
– Lower chick quality
– Increased feed costs
– Trade restrictions in breeder operations

Diagnosis
Accurate diagnosis is essential for effective control. Common diagnostic methods include:
– Serological testing (ELISA, SPA)
– PCR testing
– Culture and isolation
– Postmortem examination

Typical lesions include:
– Air sacculitis
– Tracheitis
– Foamy air sacs
– Pneumonia

Prevention and Control Measures
1. Maintain Proper Ventilation
Ensure adequate airflow without creating drafts.
2. Reduce Environmental Stress
– Maintain uniform temperature
– Avoid sudden temperature changes
w Control humidity levels
3. Strengthen Biosecurity
– Restrict visitor movement
– Disinfect equipment
– Control wild birds and rodents
4. Vaccination
Vaccination programs against MG and MS should be followed according to veterinary recommendations.
5. Early Medication
Prompt treatment using appropriate antimicrobials under veterinary guidance can reduce severity.
6. Improve Litter and Air Quality
Regular litter management helps reduce ammonia and dust.
7. Nutritional Support
Provide vitamins, electrolytes, and immune boosters during stressful weather periods.

Conclusion
Changing weather conditions significantly increase the risk and severity of Mycoplasma infections in poultry farms. Layers suffer from reduced egg production and poor egg quality, while breeders face severe reproductive and hatchability losses. Because Mycoplasma infections often become chronic and difficult to eliminate, prevention through good management, ventilation, biosecurity, and stress reduction remains the most effective strategy.

Early detection and timely intervention are essential to maintain flock health, productivity, and profitability during seasonal

Introduction
The poultry industry has emerged as one of the most dynamic and rapidly expanding segments of the livestock sector in India. Over the past few decades, the sector has transformed from a subsistence-level backyard activity into a highly organized and technologically driven industry. Poultry production plays a critical role in ensuring nutritional security by providing affordable sources of high-quality animal protein in the form of eggs and chicken meat. In addition, the sector contributes substantially to rural employment, income generation, and the growth of allied industries such as feed manufacturing, pharmaceuticals, hatcheries, and processing units. With a population exceeding 1.4 billion and steadily rising income levels, the domestic demand for poultry products has increased significantly. Despite the strong domestic market, India possesses substantial potential to expand its presence in international poultry trade. Globally, poultry meat is one of the fastest-growing sources of animal protein due to its relatively low cost, high nutritional value, and minimal cultural or religious restrictions. Consequently, many developing countries are witnessing a surge in poultry consumption. India, being among the leading producers of eggs and poultry meat in the world, has the capacity to meet a portion of this growing global demand. However, the export share of Indian poultry products remains relatively modest compared with major exporting nations. Understanding the export potential and global competitiveness of the Indian poultry sector is therefore essential for designing strategies that can enhance the country’s participation in global markets. In this article we shall try to examine the production strength, comparative advantages, export trends, constraints, and future opportunities that will determine India’s ability to become a competitive player in the international poultry trade.

Evolution and Growth of the Industry
The growth trajectory of the Indian poultry industry has been remarkable, particularly since the 1970s when scientific poultry farming began gaining momentum. Initially, poultry rearing in India was largely confined to backyard systems characterized by indigenous breeds with low productivity. The introduction of improved poultry breeds, scientific feeding practices, and better disease management gradually led to increased productivity and commercialization. Government support through various livestock development programs further accelerated the expansion of the sector. In the 1980s and 1990s, the emergence of private hatcheries, commercial feed mills, and vertically integrated poultry enterprises transformed the industry structure. Integration enabled better coordination among breeding, feed production, broiler growing, processing, and marketing activities, leading to greater efficiency and reduced production costs.

In recent years, modern technologies such as automated climate-controlled poultry houses, precision feeding systems, and improved genetic strains have significantly enhanced productivity levels. India has now become one of the largest producers of eggs and poultry meat globally. The country produces more than 149 billion eggs annually and 4.95 million tonnes of poultry meat, reflecting the rapid growth of the sector. This expansion has been supported by the availability of skilled manpower, improved veterinary services, and a strong research base in poultry science. The industry also benefits from an extensive network of small and medium poultry farmers who contribute to production through contract farming and cooperative models. The transformation of the Indian poultry sector demonstrates its ability to adapt to technological innovations and market demands, which is a crucial factor in developing export competitiveness.

Current Production Scenario
India’s poultry industry today represents a major component of the country’s livestock economy. Egg production has witnessed consistent growth over the past two decades, positioning India among the top two egg-producing nations in the world. Several states have emerged as major poultry production hubs due to favourable climate, infrastructure, and investment. States such as Andhra Pradesh, Tamil Nadu, Telangana, Karnataka, and West Bengal account for a significant share of the country’s egg and poultry meat production. These regions have developed strong production clusters supported by hatcheries, feed mills, and marketing networks. The broiler sector has also expanded rapidly, driven by increasing urban demand for poultry meat. The organized broiler industry operates through integrated production systems in which large companies provide chicks, feed, and technical support to contract farmers, while marketing the final product through established distribution channels. Such systems help maintain uniform quality and reduce production risks for farmers. Per capita consumption of eggs (106 eggs/capita/annum) and poultry meat (7.5 kg / capita / annum) in India has steadily increased as consumers recognize the nutritional benefits of these products. Eggs are considered an affordable and high-quality source of protein, vitamins, and minerals, while poultry meat is widely accepted across various cultural and religious groups. The expanding domestic market has been the primary driver of industry growth. Nevertheless, the scale of production achieved by the Indian poultry sector provides a strong foundation for exploring export opportunities, particularly in regions where demand for poultry products is growing rapidly.

Export Profile of Indian Poultry Products
Although India is among the leading producers of poultry products, its share in global poultry exports remains relatively small. The majority of poultry production in the country is consumed domestically, leaving limited quantities available for export. Nevertheless, India does participate in international trade in several poultry products. The main export items include table eggs, egg powder, liquid egg products, frozen chicken meat, and certain processed poultry products. Among these, egg powder and processed egg products constitute a significant proportion of India’s poultry exports. These products are widely used in the bakery, confectionery, and food processing industries in many countries. Major export destinations for Indian poultry products include countries in the Middle East, South Asia, and Southeast Asia. Nations such as Oman, the United Arab Emirates, Maldives, Sri Lanka, and Vietnam import eggs and poultry products from India due to geographical proximity and established trade relationships. Export volumes tend to fluctuate depending on factors such as domestic demand, international market prices, and disease outbreaks. Despite these fluctuations, the poultry export sector has shown gradual growth in recent years. However, compared with global leaders in poultry exports, India’s presence in international markets remains limited. Increasing export volumes will require improvements in processing infrastructure, quality standards, and supply chain management. Strengthening these areas will enable Indian poultry producers to compete more effectively with established exporters in the global market.

Comparative Advantages of the Indian Poultry Sector
India possesses several inherent advantages that can support the expansion of poultry exports and enhance its competitiveness in global markets. One of the most significant strengths is the large production base of eggs and poultry meat. The scale of production allows the industry to generate surplus quantities that can potentially be directed toward export markets. Another important advantage is the availability of diverse agro-climatic conditions that support year-round poultry production. This ensures a continuous supply of poultry products throughout the year, which is essential for maintaining export commitments. India also benefits from a large pool of skilled and semi-skilled labour engaged in poultry farming, processing, and marketing activities. Labor costs in India are relatively lower compared with many developed poultry-producing countries, providing a competitive edge in terms of production and processing expenses. Furthermore, the country has developed a strong research and development infrastructure in poultry science through universities, research institutes, and industry partnerships. These institutions contribute to improvements in breeding, nutrition, disease control, and farm management practices. Another advantage is the strategic geographical location of India, which allows easy access to markets in the Middle East, Africa, and Southeast Asia.
Shorter shipping distances reduce transportation costs and help maintain product quality. These comparative advantages, if effectively utilized, can significantly enhance the export potential of the Indian poultry industry.

Global Poultry Trade Dynamics
The global poultry trade is characterized by intense competition among a few major exporting countries that dominate international markets. Nations such as Brazil, the United States, Thailand, and several European countries account for a large share of global poultry exports. These countries have developed highly efficient production systems supported by advanced genetics, large-scale feed production, modern processing facilities, and strong export marketing networks. Brazil, for instance, has emerged as the largest exporter of poultry meat due to its abundant feed resources, large-scale integrated operations, and well-developed logistics infrastructure. Similarly, the United States benefits from high productivity, advanced technology, and strong global distribution systems. In contrast, many developing countries with growing poultry industries, including India, have not yet fully realized their export potential. Global poultry demand continues to rise due to increasing population, urbanization, and changing dietary preferences. Poultry meat is often preferred over other meats because it is relatively affordable, has lower fat content, and is widely acceptable across cultures. As a result, emerging economies in Asia, Africa, and the Middle East represent important growth markets for poultry exporters. For India to compete effectively in this global environment, it must improve its production efficiency, processing capacity, and compliance with international quality standards. Understanding the dynamics of global poultry trade is essential for identifying strategic opportunities and positioning Indian poultry products in suitable international markets.

Cost of Production and Feed Economics
One of the most critical factors influencing the global competitiveness of the Indian poultry industry is the cost of production, particularly the cost of feed. Feed typically accounts for nearly seventy to eighty percent of the total cost of poultry production. The major feed ingredients used in poultry diets include maize and soybean meal, both of which are subject to price fluctuations due to variations in agricultural production and market demand. In India, the prices of these feed ingredients are often higher compared with those in major poultry-exporting countries. High feed costs increase the overall cost of poultry meat and egg production, making Indian products less competitive in international markets. In addition to feed costs, other factors such as energy prices, transportation costs, and infrastructure limitations also contribute to production expenses. Improving feed efficiency through better genetics, balanced nutrition, and innovative feed additives can help reduce production costs. The development and adoption of alternative feed ingredients, including agricultural by-products and locally available feed resources, may also contribute to cost reduction. Furthermore, improvements in feed processing technologies and feed management practices can enhance nutrient utilization and overall productivity. Addressing the issue of feed cost is therefore a key requirement for strengthening the global competitiveness of the Indian poultry industry and enabling it to compete effectively with established poultry exporters.

Quality Standards and Food Safety Requirements
Access to international poultry markets depend heavily on compliance with stringent quality and food safety standards. Importing countries require strict adherence to regulations related to hygiene, product safety, and animal health. Poultry products must meet internationally recognized standards such as Hazard Analysis and Critical Control Points (HACCP), ISO quality management systems, and various sanitary and phytosanitary regulations. Additionally, many markets require certification related to halal processing, particularly in regions with large Muslim populations. Ensuring compliance with these standards requires significant investment in modern processing facilities, laboratory testing, and quality control systems. Traceability of poultry products from farm to processing plant is also becoming increasingly important in international trade. Consumers and regulatory authorities in many countries demand transparency regarding production practices, feed ingredients, and disease control measures. Indian poultry processors must therefore adopt advanced monitoring systems to maintain product quality and safety throughout the supply chain. Training of personnel in hygiene practices and quality management is equally essential. By strengthening food safety systems and ensuring consistent product quality, India can enhance the reputation of its poultry products in international markets. Improved compliance with global standards will not only facilitate export growth but also benefit domestic consumers by ensuring safer and higher-quality poultry products.

Infrastructure and Supply Chain Challenges
Infrastructure development plays a critical role in determining the export readiness of the poultry industry. In India, one of the major constraints affecting poultry exports is the limited availability of modern processing facilities and cold chain infrastructure. A large proportion of poultry birds are still marketed as live birds rather than processed products. This traditional marketing system restricts opportunities for value addition and limits the shelf life of poultry products. Export markets generally require processed, packaged, and frozen poultry products that can withstand long-distance transportation. The availability of refrigerated storage facilities, cold transport vehicles, and efficient port infrastructure is essential for maintaining product quality during export. Inadequate cold chain logistics can lead to spoilage and quality deterioration, reducing the competitiveness of poultry exports. Furthermore, transportation costs and logistical inefficiencies can increase the final price of exported products. Strengthening supply chain infrastructure through investments in modern slaughterhouses, cold storage units, and refrigerated transport systems is therefore essential for expanding poultry exports. Public-private partnerships and government support programs can play an important role in developing such infrastructure. Improved logistics and supply chain management will enhance the efficiency of poultry exports and ensure that Indian products reach international markets in optimal condition.

Opportunities in Emerging Markets
Despite the challenges faced by the poultry sector, several opportunities exist for expanding India’s presence in global poultry trade. One of the most significant opportunities lies in the rapidly growing demand for poultry products in developing regions such as Asia, Africa, and the Middle East. Population growth, rising incomes, and urbanization in these regions are driving increased consumption of animal protein. Poultry meat, being relatively affordable and easy to prepare, is often the preferred choice among consumers. India’s geographical proximity to many of these markets provides a logistical advantage in terms of transportation time and cost. Additionally, cultural similarities and established trade relationships with several Asian and Middle Eastern countries can facilitate market access. Another important opportunity lies in the production of value-added poultry products such as ready-to-cook and ready-to-eat items. The global demand for convenience foods is increasing as urban lifestyles become more hectic. Indian poultry processors can capitalize on this trend by expanding the production of processed and packaged poultry products. Developing specialized export zones for poultry processing and strengthening branding and marketing strategies can further enhance India’s export prospects. By focusing on emerging markets and innovative product development, the Indian poultry industry can significantly increase its share in international poultry trade.

Strategic Interventions for Enhancing Competitiveness
To fully realize its export potential, the Indian poultry industry must adopt a series of strategic interventions aimed at improving productivity, quality, and market access. One of the primary priorities should be the modernization and expansion of poultry processing infrastructure. Establishing more integrated processing plants equipped with advanced technology will enable the production of high-quality export-oriented poultry products. Strengthening veterinary services and disease surveillance systems is also crucial for preventing outbreaks that could disrupt export trade. Investments in research and development are needed to improve poultry genetics, nutrition, and disease management practices. The development of cost-effective feed formulations using locally available ingredients can help reduce production costs. Additionally, capacity building programs should be implemented to train farmers, technicians, and processing personnel in modern poultry management and food safety practices. Government policies aimed at promoting agricultural exports, including financial incentives and infrastructure development programs, can further support the growth of poultry exports. Collaboration between government agencies, research institutions, and the private sector will be essential for implementing these strategies effectively. By adopting a coordinated approach that integrates technological innovation, infrastructure development, and policy support, India can significantly enhance the global competitiveness of its poultry industry.

Future Outlook
The Indian poultry industry has achieved remarkable progress over the past several decades, evolving into one of the most vibrant sectors of the country’s agricultural economy. With a large production base, expanding domestic demand, and improving technological capabilities, the industry possesses substantial potential to become a significant exporter of poultry products. However, realizing this potential requires addressing several structural challenges, including high feed costs, limited processing capacity, inadequate cold chain infrastructure, and strict international quality requirements. Strengthening these areas will be critical for enhancing the competitiveness of Indian poultry products in global markets. At the same time, the growing global demand for affordable animal protein presents significant opportunities for export expansion. By focusing on value-added poultry products, improving supply chain efficiency, and ensuring compliance with international food safety standards, India can strengthen its position in international poultry trade. Continued investment in research, infrastructure, and policy support will play a vital role in achieving this objective. In the coming years, the integration of modern technologies, sustainable production practices, and export-oriented strategies is likely to transform the Indian poultry industry into a globally competitive sector. Such progress will not only generate additional export earnings for the country but also contribute to rural development, employment generation, and improved nutritional security.

1. Introduction: origin and persistence of the hormone myth
One of the most widespread misconceptions surrounding poultry meat and eggs is the belief that growth hormones are routinely used in the poultry meat and egg industry to increase body weight, accelerate growth, or enhance egg production. This misconception persists despite enormous scientific evidence and strict regulatory bans across major poultry-producing countries. Consumer perception studies conducted in Asia and Europe report that 70–90% of respondents believe hormones are added to broiler chickens and laying hens, often associating poultry meat and eggs with health risks such as early puberty, hormonal imbalance, and cancer (Karasu & Öztürk, 2021;). Unfortunately, this misunderstanding is amplified by misleading media narratives and the misinterpretation of naturally occurring hormones present in all living organisms. Both chicken meat and eggs naturally contain trace levels of endogenous hormones, but these are produced by the birds themselves and are not the result of external hormone administration (Courtheyn et al., 2002).

This misinformation negatively impacts consumer trust, poultry farmers, and allied industries while diverting attention from genuine food safety issues such as nutrition, sustainability, and antimicrobial resistance. International authorities including the FAO, WHO, FDA, and European Commission have repeatedly clarified that neither broiler chickens nor laying hens are given growth or production hormones (FDA, 2023). Addressing this myth with evidence-based communication is essential for informed consumer choice and public confidence in the poultry meat & eggs.

2. Scientific reality: hormones are not used in poultry meat or egg production
From a biological, practical, and economic standpoint, the use of hormones in poultry meat or egg production is neither effective nor feasible. Comprehensive scientific reviews confirm that no hormone products are approved or used in broiler chickens or commercial laying hens (Esquivel-Hernández et al., 2016). Unlike cattle, poultry have a very short production cycle, and their endocrine systems respond poorly to externally administered growth hormones. Experimental studies evaluating somatotropin and steroid hormones in chickens have consistently shown no significant improvement in growth rate, feed efficiency, or egg production (Scanes, 2009). In laying hens, egg production is regulated by tightly controlled physiological mechanisms involving the hypothalamic–pituitary –gonadal axis, which cannot be manipulated safely or effectively through exogenous hormone supplementation (Johnson, 2015).

In this all controversy, even if protein-based hormones were administered, they would be degraded during digestion, making oral delivery ineffective, while injection is impractical in commercial systems housing thousands of birds (Esquivel-Hernández et al., 2016). Moreover, hormone compounds are expensive and incompatible with the low-margin economics of poultry and egg production. As a result, no scientifically rational or commercially viable pathway exists for hormone use in poultry sector.

2.1. Regulatory Prohibition of Hormone Use in Poultry Production
Regulatory agencies reinforce this reality. The U.S. FDA explicitly states that hormones are not permitted in poultry or egg production, and no hormone-based drugs are approved for laying hens (FDA, 2023).

Similarly, the European Union banned growth hormones in food animals decades ago, with strict monitoring programs ensuring compliance (European Commission, 2018). These regulations apply equally to meat- and egg-producing birds.

3. Genetics, nutrition, and management: the true drivers of broiler growth and egg production
The enhanced productivity of today’s broilers and laying hens is the result of decades of systematic genetic selection, supported by precision‑based nutrition and advanced management practices, rather than hormone use. Early evidence for this genetic progress was demonstrated by Havenstein et al. (2003), who showed that modern broilers reach market weight nearly twice as fast as birds from the 1950s when fed the same diets, clearly confirming that genetics, not hormones driven growth improvements. Over successive generations, selective breeding programs have focused on birds with superior growth potential and efficient feed conversion ratio (FCR), enabling higher body weight gain from less feed consumption. Continued genetic selection has subsequently enhanced muscle fibre deposition efficiency, particularly in the breast muscle, leading to higher lean meat yield. These improvements are achieved using selection indices that integrate growth, efficiency, health, and welfare traits, ensuring sustainable productivity without compromising biological integrity (Zuidhof et al., 2014).

Similarly, long‑term genetic selection has improved egg number, shell quality, and feed efficiency in laying hens, allowing modern layers to produce over 300 eggs per year without compromising health (Hunton, 2005). These genetic gains are supported by precision‑based nutrition, with carefully balanced diets optimizing growth, reproduction, and egg production (Pattison et al., 2008). In parallel, advancements in housing systems, automation, biosecurity, and environmental management have further enhanced bird welfare and productivity, collectively explaining modern poultry performance without the use of hormones.

4. Hormones in poultry meat and eggs: scientific context and safety
All animals, including poultry and humans, naturally produce hormones such as oestrogen, progesterone, and testosterone as part of normal physiology. Consequently, trace amounts of these hormones are naturally present in chicken meat and eggs, but they are not added externally (Stephany, 2010). These levels are extremely low and biologically insignificant when consumed. The FAO/WHO Joint Expert Committee on Food Additives (JECFA), during its evaluations of residues in foods of animal origin, concluded that naturally occurring hormone residues pose no health risk to consumers, including children and adolescents (FAO/WHO, 2011). Therefore, claims linking poultry meat or eggs to hormonal disorders lack scientific validity. Misleading marketing terms such as “hormone-free chicken/eggs” can unintentionally reinforce public fear by implying that hormones are normally used, when in fact they are legally prohibited (Verbeke et al., 2010). Clear, science-based communication is essential to correct this misunderstanding.

5. Role of social media in misinformation influencing Consumers psyche and its impact on poultry industry
In recent years, the rapid growth of social media has enabled the spread of unverified and misleading information, often driven by poorly informed influencers or non-expert online sources seeking digital attention through fear‑based and sensational claims. Many people are aware that anabolic steroids are used by humans for bodybuilding or rapid muscle growth, and this awareness has led some influencers to wrongly associate various steroid use with the fast growth of broiler chickens. This misinformation has significantly influenced consumers especially household women and mothers who are responsible for family meals and concerned about their children’s and family health, resulting in reduced broiler chicken consumption. In reality, broiler chickens are not grown using hormones or steroids. Their rapid growth is the result of decades of genetic selection, balanced and precise nutrition, and improved farm management practices. Thus, broiler growth is natural within genetic potential, not artificial or hormone‑driven, underscoring the urgent need for science‑based communication and digital literacy.

6. Conclusion: The belief that hormones are used in the poultry meat or egg industry is scientifically incorrect, biologically implausible, and legally prohibited. Modern poultry and egg production rely on genetics (Selective Breeding), precision nutrition, health management, and environmental control not artificial hormones. Regulatory agencies worldwide strictly enforce these standards, ensuring food safety and consumer protection (FDA, 2023;). Continuing to spread hormone-related myths distracts from real challenges such as antimicrobial resistance, climate resilience, and sustainable production systems (WHO, 2017). Scientists, veterinarians, medicos, poultry industry allied professional and media professionals have a shared responsibility to communicate evidence-based facts clearly, responsibly and aware to public about rumours and misconceptions. By communicating accurate, evidence‑based information, stakeholders can first ensure that consumers are properly informed, which in turn builds trust and credibility for producers. Consequently, dismissing hormone‑related myths across the poultry meat and egg industries is essential for protecting public health, strengthening food security, and maintaining confidence on poultry industry.

Introduction

Newcastle Disease (ND), caused by Avian Paramyxovirus Type-1 (APMV-1), remains one of the most devastating viral infections affecting the poultry industry in India. With high mortality rates, reduced egg production, and severe economic losses, ND poses a constant threat to both small-scale poultry farmers and large commercial producers. Despite advancements in vaccination and biosecurity, the disease continues to challenge the sustainability of India’s poultry sector, which contributes significantly to the nation’s agricultural GDP.

Newcastle Disease: A Persistent Menace

Newcastle Disease is highly contagious, affecting chickens, turkeys, and other avian species. The virus spreads through direct contact, contaminated feed, water, equipment, and even airborne transmission. Clinical signs vary depending on the strain but commonly include:

• Respiratory distress (gasping, coughing, nasal discharge)
• Nervous signs (twisting of the neck, paralysis, tremors)
• Greenish diarrhoea
• Sudden drop in egg production (thin-shelled or shell-less eggs)
• High mortality (up to 100% in unvaccinated flocks)

In India, velogenic strains (highly virulent) are predominant, causing severe outbreaks that cripple poultry operations. (APMV-1 Velogenic NDV is responsible for Velogenic Viscerotropic ND (VVND) outbreaks in India).

Economic Impact on the Indian Poultry Industry

India is the third-largest egg producer and fifth-largest poultry meat producer globally, The poultry sector in India, valued at more than USD 28 billion in 2021-22, has been a vital component of the country’s agriculture and food processing industry. Newcastle Disease disrupts this growth through:

1. Direct Losses Due to Mortality & Culling

• Unvaccinated or poorly managed flocks face mortality rates of 80-100%, leading to massive financial losses.
• Government-mandated culling during outbreaks further exacerbates losses.

2. Reduced Egg & Meat Production

• Layers: A single ND outbreak can cause a 20–50% drop in egg productionand reduce egg quality, with recovery taking weeks.

• Broilers: Cause severe mortality. Infected birds suffer stunted growth, leading to lower market weights and downgrading at processing plants.

3. Increased Vaccination & Treatment Costs

• Farmers must invest in regular vaccination schedules (Live & Inactivated ND vaccines), adding to operational costs.
• Secondary bacterial infections (E. coli, Mycoplasma) increase antibiotic usage, raising concerns over antimicrobial resistance (AMR).

4. Trade Restrictions & Market Losses

• ND outbreaks lead to quarantine zones, restricting movement of poultry and products.
• Export markets (Middle East, Southeast Asia) impose bans on Indian poultry products during outbreaks, causing revenue losses.

5. Impact on Small & Marginal Farmers

• Over 70% of Indian poultry farmers are small-scale, lacking resources for strict biosecurity.
• A single ND outbreak can bankrupt small farmers, pushing them out of the industry.

Strategies to Combat Newcastle Disease

1. Strict Vaccination Protocols
2. Enhanced Biosecurity Measures

• Farm-level hygiene: Disinfection of footwear, vehicles, equipment.
• Restricted access: Prevent contact with wild birds & other farms.
• All-in-all-out systems: Reduce viral persistence in multi-age flocks.

3. Early Detection & Rapid Response

• Regular serological monitoring (HI tests for antibody titers).
• Rapid reporting of suspected cases to Veterinarians.

4. Proactive Measures for ND Outbreak Prevention

• Compulsory ND vaccination programs in high-risk zones.
• Farmer awareness campaigns on biosecurity best practices.

Conclusion: A Call to Action

Newcastle Disease is not just a health issue—it’s an economic catastrophe for India’s poultry industry. With the sector growing at 8-10% annually, unchecked ND outbreaks disrupt livelihoods and threaten national food security.

The solution lies in:
 Proactive vaccination
 Robust biosecurity
 Farmer education
 Stronger policy enforcement

As veterinarians, researchers, and industry leaders, we must unite to safeguard Indian poultry from Newcastle Disease—ensuring sustainability for farmers and safe, affordable protein for millions.

A recent research program highlights that micro-encapsulation of seaweed and plant extracts can stimulate digestive functions, improve performance, and reduce feed costs, addressing current egg industry needs.

The egg industry grapples with key challenges in optimizing nutrition and profitability for laying hens. One significant hurdle involves efficiently producing eggs while maintaining bird health and well-being. Sustainable practices, such as efficient waste management and reducing the environmental footprint, are essential to address growing concerns about the environmental impact of egg production. To tackle these issues and enhance the performance of laying hens, strategies have emerged. These include formulating balanced diets with alternative protein and energy sources, exploring feed additives like enzymes, microbials, phytogenics, and seaweed extracts. Enzymes, such as phytase, improve nutrient utilization, while probiotics and prebiotics support gut health, enhancing feed conversion and disease resistance. Natural phytogenics provide antioxidants, affect the microflora profile, and improve digestive functions, ultimately leading to increased egg production and improved egg quality. Seaweed bioactives (so called-phycogenics), contribute as well to better gut health of animals. These strategies address challenges in egg production and meet consumer expectations for high-quality, nutritious eggs, all while promoting sustainable and eco-friendly practices.

The latest benchmark for phytogenic feed additives
Lately, a feed additives company has introduced an innovative product, NUQO©NEX (NQ), comprising metabolites sourced from both plants and algae (referred to as phytogenic and phycogenic, originating from the Greek words ‘phytos’ for plant and ‘phycos’ for algae). These metabolites are shielded by a unique micro-encapsulation technology. The utilization of micro-encapsulation has become imperative in the realm of phytogenic feed additives to mitigate the volatility of natural compounds. While the term ‘encapsulation’ is increasingly generic, it is crucial to discern authentic technology that not only safeguards but also effectively releases active ingredients, setting it apart from rudimentary methods like silica absorption or light-agglomeration, which may suffice for various compounds but fall short in preserving delicate phytogenics like essential oils.

It is of utmost importance to delve into the manufacturing technology underpinning each product, rather than solely relying on surface-level claims. With its notably high concentration of active components and remarkable stability, this novel solution assures a precise release in the digestive tract and offers a cost-effective dosage unlike any other currently available. This technology has been meticulously developed to optimize poultry performance and can serve as an alternative growth promoter or a means to enhance feed conversion ratios and overall performance, ultimately resulting in an improved return on investment for poultry operations.

Numerous trials have validated the effectiveness of this technology in enhancing the performance of laying hens across diverse contexts and geographic regions. Concurrently, scientists have conducted assessments to gauge the technology’s precise influence on feed digestibility. This research aims to provide formulators and nutritionists with greater flexibility in their decision-making processes.

Enhancing Feed Digestibility in poultry
In a recent study conducted at the University of Berlin in Germany, researchers undertook a comparative analysis of four treatments: a negative control, two commercial products incorporating phytogenics (referred to as P1 & P2), and a novel technology, NUQO©NEX (NQ). The findings revealed that the NQ treatment not only enhanced the digestibility of nutrients like crude fat, crude protein, and starch but also contributed to increased mineral digestibility, including crude ash, calcium, and phosphorus, when compared to the negative control. The other two solutions also improved the digestibility of certain nutrients and minerals but to a lesser extent than NQ. Notably, the NQ treatment exhibited the most pronounced effects on nutrient and mineral digestibility, resulting in the highest overall performance improvement. In sum, the NQ treatment demonstrated enhanced feed digestibility, ultimately leading to improved performance, in contrast to conventional products relying on phytogenics. This underlines the significance of the formulation’s composition (comprising both phytogenics and phycogenics) and the influence of manufacturing technology (micro-encapsulation) on product stability and release within the digestive system.

Concrete impact on feed costs with a conservative matrix value
The NQ technology underwent extensive testing in various global regions, including Asia, Europe, and Latin America, to evaluate its impact on the performance of laying hens. Additionally, to offer maximum flexibility to nutritionists and formulators, diverse scenarios were examined, involving the application of feed additives either “on top” of the formulation or using a “matrix value” approach, allowing adjustments to the feed formulation to reduce costs by decreasing energy and protein content. Two recent trials were conducted at Kasetsart University in Thailand under the guidance of Professor Yuwares.

In an experiment, the NQ technology was used with a “matrix value” at 75 ppm. Three treatments were tested: 1) an initial control diet [C0], 2) a second treatment that consisted of the same control diet but with reduced energy and protein content (-23 kcal/-0.25% dig.Prot) [NC], and finally, 3) a third treatment was given to animals based on the control diet, with reduced energy and protein content (-23 kcal/-0.25% dig.Prot) along with the NQ technology at 75 ppm [NC+NQ]. In this case as well, the experiment consistently delivered expected results. Applying a matrix to the control diet (NC) adversely affected laying percentage, egg mass, and FCR but did not alter feed intake when compared to the control. Applying NQ technology with a matrix value (NC+NEX) helped to restore layer performance, with the laying percentage even slightly surpassing that of CO.

Beyond performance indicators, additional assessments highlighted the influence of the NQ technology. Researchers observed a decrease in both fatty liver scores and occurrences. Moreover, there was an enhancement in eggshell thickness, whether the technology was used in a diet, with or without a matrix value.

Opt for the latest, science-backed technology to safeguard profits
In the evolving landscape of the egg industry, the NQ technology emerges as a revolutionary solution. By seamlessly combining exclusive ingredients sourced from both plants and algae, it offers a distinctive advantage. What sets this technology apart is its genuine micro-encapsulation method, ensuring the safe and efficient release of active components. Through extensive trials, the remarkable effects on laying hens’ performance, improved feed digestibility, enhanced egg quality, and notable reduction in costs have been demonstrated. NQ technology is not just one more phytogenic feed additive, but rather the most advanced nature-based technology for optimizing laying hens’ performance at competitive cost. It serves as a cornerstone for the future of egg production, delivering unparalleled advantages to producers and championing healthier, more sustainable laying hens’ operations.

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.

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.
