s the global poultry sector prepares for EuroTier 2026, this edition of aviNews International takes a clear stance: incremental fixes are not sufficient. Poultry production needs coordinated action: rigorous biosecurity, pragmatic technology adoption, and nutrition and management grounded in modern science. We lead with biosecurity because nothing else matters if flocks are exposed; perimeter control, disciplined entry protocols, and trained personnel are the baseline for resilience, not optional extras. That baseline is what makes technology effective rather than decorative. With a secure farm footprint in place, AI moves from novelty to necessity. Ricky Thaper’s report from India shows AI delivering real, measurable gains in monitoring, feed optimization, early disease alerts, and demand forecasting. Data without discipline is noise; data applied to disciplined practice is power. The same principle applies to enterprise systems. Udaykumar Mudbakhe’s ERP account is a cautionary tale: software that ignores shop‑floor realities creates friction, not foresight. The industry must insist on systems that measure what matters, integrate physical measurements, and surface risk before it becomes a crisis. At the processing end, objective tools are overdue. Auburn University’s multispectral imaging work on sep‑tox detection points to inspection that supports human judgment: reducing fatigue, improving consistency, and protecting yield.
When inspection becomes more reliable, the whole value chain benefits from fewer condemnations and clearer regulatory evidence. Nutrition and early management close the loop between technology and biology. We explore the second part of egg size versatility in Nick Chick, with emphasis on the layer nutrition. That, along with NASEM 10th edition push feed formulation toward digestibility‑aware, evidence‑based strategies; precision nutrition is now a strategic requirement for predictable economics. Meanwhile, uniformity starts in the hatchery: a narrow hatch window, Genesys gender sorting, and immediate water access are not marginal tweaks but investments that determine flock trajectory. Gut health and villus metrics remind us that biology still sets the limits for technology. As antibiotic use tightens and consumer expectations rise, understanding intestinal function becomes essential to translate nutrition and management into performance. This edition is unapologetically practical: protect flocks with rigorous biosecurity, adopt technologies that demonstrably improve decisions, insist on ERP and analytics that reflect reality, and treat early‑life management and precision nutrition as strategic priorities. EuroTier is where we will debate tools – but the industry must leave Hanover ready to act. Enjoy the reading!

T
he poultry sector in India has become a crucial part of the agricultural landscape, playing a vital role in the economy through job creations, progress, and ensuring protein security. Largely driven by a rising consumer demand for protein-rich foods, especially poultry meat, the industry has seen significant expansion in the last three decades.
At present, the Indian poultry industry is witnessing an annual growth rate of 7-8%. The industry has transformed itself from following conventional farming practices to a modern commercial production system. In India, the poultry supply chain has undergone significant transformations with the advent of modern technologies such as cold storage, automated feed mills, and advanced processing techniques.
14 aviNews International September 2026 | Usage of Artificial Intelligence (AI) Tools to Ensure Sustainable Growth of Indian Poultry Industry
The shift from the traditional diet, which earlier relied on pulses consumption, to food products such as meat, eggs, and dairy products to meet the protein requirements significantly boosted the Indian poultry industry growth.
AT PRESENT:
India is the second largest producer of eggs in the world and the fourth largest producer of poultry meat in the world.
Total annual broilers placement in India is approximately 5.5 billion.
Total layer placement in India is close to 300 million annually.
Poultry products are often more affordable than other protein sources, making them accessible to a broader segment of the population.
Management
According to industry estimates, the sector is projected to grow at a compound annual growth rate (CAGR) of 8.10% over the next decade. This growth is propelled by factors such as rising demand for protein products, urbanization, and increased consumption of poultry products.
Broiler breeder placement is 55 million annually and layer breeder placement is 22 million.
The poultry feed production is 28 million tons.
The annual per capita consumption of eggs in India at present is 103 eggs, while poultry meat consumption is 7.4 kg.
The sector employs an estimated 6 million people directly or indirectly in poultry industry.
The Indian poultry equipment sector is estimated around USD 180 million, and the poultry feed additives and medicine sector is estimated around USD 700 million.

KEY AREAS OF APPLICATIONS The poultry sector is supported by factors including conducive climatic conditions, reasonable labor costs, and the government initiatives such as the national livestock mission and Animal Husbandry Infrastructure Development Fund aimed at enhancing infrastructure and biosecurity.
RISING ROLE OF AI IN POULTRY INDUSTRY The growing importance of artificial
Management
intelligence (AI) in the poultry industry has increased in recent years. AI is gradually being used in several complex operations in a poultry farm including feeding, water, sanitization, disease management through early warning and overall management of birds.
1
Data analytics AI algorithms or tools analyze vast amounts of data collected from poultry farms, including environmental conditions inside the farm, volume of feed consumption, indicators of bird health, and production matrix. These AI tools using these data can predict trends, detect anomalies, and optimize various aspects of the production system for ensuring efficiency and boosting farmer’s income. AI’s benefits also extend to postharvest activities for broiler chickens and egg collection. By analyzing bird movement patterns and behavior, the algorithms can identify areas of congestion or stress and suggest layout modifications to improve living conditions.
As the Indian poultry industry leaps into a new phase of its growth, sustainable growth of the industry assumes paramount importance.
AI driven tools help optimum utilization of water, feed, and energy in a poultry farm. Tools such as machine learning, deep learning, and reinforcement learning are currently offering new opportunities for addressing complex challenges in poultry farming and are providing new insights into animal behavior, health, and productivity.

Real time monitoring management AI-powered systems can monitor poultry houses in real-time using sensors to track parameters such as temperature, humidity, air quality and water consumption. This real time monitoring helps identify factors such as ventilation or air circulation in a poultry farm, disease outbreaks, which lead to healthy birds and growth. AI-driven ventilation systems can adjust airflow rates and temperature settings based on real-time data, ensuring optimal conditions for bird comfort and their health.
4
Disease detection and biosecurity AI systems enable data analysis of bird behavior, physiological indicators, and environmental conditions inside the farm, to detect signs of disease outbreaks early.
3
AI-driven systems are enhancing biosecurity measures on poultry farms by analyzing data on farm operations and visitor movements. These systems can identify potential biosecurity risks and suggest mitigation measures.
Feed management AI tools help optimize feed formulations based on factors like bird age, weight, health status, and nutritional requirements. By precisely adjusting feed compositions, these tools help maximize growth rates of birds, minimize feed wastage, and reduce feed costs, which accounts for 60-65% of production costs. AI-enabled feeders automatically adjust the feeding schedule and quantity based on real-time data, ensuring that layer and broiler birds receive the optimum feed based on their nutritional needs.
Management
This early detection of bird flu and other diseases enable prompt intervention measures, such as targeted treatments through following biosecurity protocols, to contain the spread of disease and minimize losses.
These tools prevent the introduction and spread of diseases like avian influenza, which can have devastating impacts on the poultry sector.
5
Projection of demand and supply AI data analytics tools and software are currently available to poultry producers, enabling them to analyze historical data, market trends, and consumer behavior. These tools support poultry farmers to make informed decisions regarding production volumes and timing. India’s diverse consumption pattern influenced by religious factors can be assessed using AI tools which capture seasonal variations in demand and supply.
17 aviNews International September 2026 | Usage of Artificial Intelligence (AI) Tools to Ensure Sustainable Growth of Indian Poultry Industry
The demand forecasting provides poultry businesses with accurate predictions of future demand, enabling them to optimize production schedules and avoid overproduction or underproduction. By aligning production with anticipated demand, the industry can minimize waste, reduce costs, and ensure efficient utilization of resources while maintaining optimal inventory levels.
Management
6
Precision breeding and genetics Through the machine learning method, AI processes genetic information, health records, and environmental data, which helps predict which breeding combinations will produce healthier, more robust chickens. It identifies traits that enhance not only growth but also health and resilience. AI tools identify genetic markers associated with desirable traits such as growth rate, feed efficiency, disease resistance, and egg production. These applications help breeders make more informed decisions in selecting breeding stock, accelerating the breeding process, and producing poultry with improved traits.
7
Robotics AI-powered robots are increasingly being deployed in poultry farms for tasks such as egg collection, cleaning, and disinfection. These robots can work autonomously or under supervision of human support improving efficiency in the poultry unit management. By automating this labor-intensive process, farmers can increase operational efficiency, minimize egg breakage, and improve overall egg quality. In addition, robotic cleaners equipped with sensors can detect and remove waste material from the poultry units, reducing ammonia levels, and improving air quality for both birds and workers.
CONCLUSION The potential of AI in the Indian poultry industry is immense, as it addresses several challenges faced by the value chain which is aiming to boost production efficiency.

WHEN ERP MET REALITY: A MANUFACTURING STORY FROM 2007, AND WHY I’M HOPEFUL TODAY Management
Udaykumar Mudbakhe (Patil) Poultry Production Consultant
ERP (Enterprise Resource Planning) systems record the past, but the people on the shop floor are responsible for predicting the future.
Recently, while reading about the emergence of advanced artificial intelligence (AI) models such as Claude in enterprise management systems, I found myself reflecting on an experience from nearly two decades ago.
It reminded me how technology and operational reality often evolve at different speeds, and how lessons from the shop floor can shape our expectations for future systems.
20 aviNews International September 2026 | When ERP Met Reality: A Manufacturing Story from 2007, and Why I’m Hopeful Today
keep the plant running smoothly. At full capacity, we were producing approximately 100 tons of poultry feed every day. At that scale, numbers are not abstract. Even a small percentage error quickly becomes significant. A 1% deviation does not remain a spreadsheet anomaly; over time, it translates into truckloads of material.
During this period, the company decided to implement Microsoft Dynamics as the ERP backbone through a large IT services organisation and their third-party consultants. On paper, it appeared to be the perfect solution. ERP promised better control, visibility across departments, traceability of materials, and scalability for future growth. For a rapidly expanding manufacturing operation, it seemed like the right step forward.
To be fair, many things did improve. Documentation became structured, transactions were recorded systematically, and reports became available in a standardized format.
However, this story is not about whether ERP systems are good or bad. It is about what happens when systems are implemented without fully understanding the people and processes that operate on the shop floor.
The promise of ERP vs the reality of the shop floor After the ERP system was implemented, I began receiving what most managers would consider a complete reporting setup: Daily inventory reports Production report Sales reports
Every number was available. Every transaction was captured. At first glance, the system seemed to provide a comprehensive picture of operations. Yet something felt incomplete.
Management
In 2007, I was leading a newly established poultry feed manufacturing division. As the first employee of that division, I was responsible for nearly everything—inventory, warehouse management, production coordination, procurement discussions, and the daily operational decisions required to
The reports explained the past: What had been produced yesterday What had been sold What stock remained in inventory But they did not help answer the questions that mattered most in daily operations: What might go wrong tomorrow? Which deviations are normal and which are dangerous? Which raw material might become critical in the coming days? Those answers were not present in the system. They existed only in the experience and intuition of the people running the plant.
aviNews International September 2026 | When ERP Met Reality: A Manufacturing Story from 2007, and Why I’m Hopeful Today

The first cracks: Forms, fields, and missing logic The first operational gaps appeared in something as basic as data capture. Purchase orders, goods receipt notes, and sales orders existed in the system, but several practical issues emerged: Mandatory fields were not clearly defined Data types were loosely structured Units of measurement wereinconsistent
Management
Packaging was treated as a description rather than a logical component of inventory In feed manufacturing, quantity is never just quantity. A bag is not merely a bag.
Production shrinkage: When physics meets accounting Feed manufacturing involves several natural sources of shrinkage: Grinding losses Mixing losses Moisture variation Handling and transfer losses
These are not anomalies. They are expected and measurable parts of the production process. However, the system logic effectively assumed a simplified equation: Input = Output. At a daily output of 100 tons, even a predictable 5% shrinkage results in:
Gunny bags have weight 5 tons of material loss per day HDPE bags have weight Approximately 150 tons per month Over thousands of bags, this weight accumulates significantly
However, the ERP system captured gross quantities, while operational reality functioned on net usable material. Over time, small discrepancies began to accumulate. Every inward movement slightly inflated the recorded stock. Every outward movement created unexplained shortages. On paper, the system appeared correct. On the shop floor, the differences were visible.
Nearly 1,800 tons per year This was not a rounding error—it represented a substantial quantity of material. Because the system could not model expected process losses, it treated all losses as deviations. And when systems cannot explain physical reality, they tend to question the people operating them. Reconciliation meetings became routine. Instead of focusing on improving production, much of the conversation revolved around explaining variances. At times, it felt as if I was not managing production—I was defending the laws of physics to software.

Contract purchasing vs market selling: The costing paradox Another layer of complexity came from the way raw materials were procured and finished products were sold. Raw materials such as maize, soya DOC, and groundnut DOC were purchased on period contracts with daily deliveries at agreed prices. Finished feed, however, was sold based on prevailing market rates.
Management
To manage margins responsibly, operational costing needed to consider: Average stored raw material cost
This approach helped stabilize decision-making and prevented overreaction to daily price fluctuations. However, the ERP system valued inventory using accounting rules such as: Transaction-based valuation FIFO or moving average logic Ledger-oriented calculations This created two parallel truths: One for operational decision-making One for accounting reporting
Operating cost Packaging cost
Both were technically correct. But the system did not explain why they differed.

Management

“This is best practice.” “This is industry standard.” “Customization is not recommended.” Management naturally trusted the external consultants. This became the most difficult phase—not technically, but emotionally. When you clearly see a structural issue yet cannot influence change, frustration builds quietly.
The turning point: Hiring a local developer The real transformation happened gradually. I hired a local developer—not a large consulting firm or a well-known brand. But he did one very important thing: He listened. Together we made a focused decision: Integrate the weighbridge directly with the ERP system. This single step aligned physical measurement with digital records. Manual data entry errors decreased, and the system began capturing reality at the source. More importantly, he taught me: Basic SQL Table structures Form logic How ERP systems actually process data

This experience changed my perspective. I moved from being simply a system user to becoming a translator between operational thinking and software logic. A single targeted integration delivered more clarity than months of discussions.
What was still missing: Foresight Even after improvements, one important gap remained. The ERP system provided: Inventory visibility Production records Sales tracking

Why I feel hopeful today
The core lesson
Today, enterprise technology is evolving rapidly. Advanced AI models such as Claude from Anthropic are beginning to demonstrate contextual reasoning over structured operational data.
Systems rarely fail because of lack of data. They struggle when they ignore: Context Physical processes
What gives me hope is not automation—but interpretation. ERP systems already contain vast amounts of data. What they historically lacked was a reasoning layer capable of understanding operational context.
Management
Instead of a static report such as: “Inventory: 820 tons.” Imagine receiving a practical operational insight like: “At the current production rate, maize inventory will reach a critical level in three days.” “Shrinkage has exceeded expected range for four consecutive batches.”
Domain experience For many years, intelligence lived in people while systems merely stored transactions. Today, we have the opportunity to combine both. If technology begins to listen to operations rather than simply recording them, enterprise systems can move beyond documenting the past—and begin helping organisations navigate the future. If you have ever looked at a report and felt that the numbers were correct, yet the decision still felt uncertain, you are not alone. Perhaps the next generation of systems will not only calculate, but also interpret.
“Current raw material cost trends may reduce margins next week.” That is the lesson my manufacturing floor taught me—and why, today, I remain hopeful. These insights are not futuristic ideas. They are the very thoughts plant managers already carry in their minds. If intelligent systems can translate operational intuition into structured insight, the gap between physical reality and digital reporting can finally begin to close.

ADVANCING SEP‑TOX DETECTION:
HOW MULTISPECTRAL IMAGING AND AI COULD TRANSFORM BROILER CARCASS INSPECTION
Processing
Micah T. Black, PhD Student Department of Poultry Science, Auburn University, Auburn AL
Septicemia‑toxemia (sep‑tox) continues to be one of the most consequential causes of broiler carcass condemnation in modern poultry processing. Although the condition affects less than 0.2% of birds entering U.S. processing plants, the scale of production, which accounts for more than 9 billion broilers annually, means millions of carcasses are removed from the market each year.
The economic impact is significant, and the regulatory implications are even more critical: the US Department of Agriculture-Food Safety and Inspection Service (USDA‑FSIS) maintains a zero‑tolerance policy for carcasses exhibiting signs of systemic disease. At the same time, processors operating at line speeds of 140-175 birds per minute, find the identification of sep‑tox accurately and consistently both a regulatory requirement and an operational challenge.
31 aviNews International September 2026 | Advancing Sep‑Tox Detection: How Multispectral Imaging and AI Could Transform Broiler Carcass Inspection
A promising technological solution comes to alleviate the challenge: a handheld multispectral optical imaging system combined with machine learning algorithms capable of detecting sep‑tox rapidly and with high accuracy. The research demonstrates how optical imaging and artificial intelligence could support, and potentially revolutionize, carcass inspection in high‑throughput environments.
Processing
This article summarizes the study’s methodology, findings, and implications for the poultry industry, offering a technical yet practical perspective for processors, integrators, and equipment innovators.
Given USDA‑FSIS’s zero‑tolerance policy for unwholesome carcasses, false nega‑ tives pose food‑safety risks, while false positives reduce yield and profitability. The industry has long sought objective, automa‑ ted tools to support inspectors, especially as line speeds increases under the imple‑ mentation of the New Poultry Inspection System or NPIS by the USDA-FSIS.
WHY SEP‑TOX DETECTION IS SO DIFFICULT YET SO IMPORTANT Sep‑tox encompasses systemic bacterial infections that enter the bloodstream (septicemia) or produce toxins locally (toxemia). Affected carcasses typically show: Red to bluish discoloration Petechial hemorrhages on organs and muscle Dehydrated skin Stunted growth or smaller carcass size Excess fluid in the chest cavity These symptoms can vary in intensity, and visual inspection is inherently subjective. Inspectors must evaluate each carcass and its viscera under a lot of time pressure, often performing repetitive motions that contribute to fatigue and muscu‑ loskeletal disorders. Studies have shown that more than 80% of processing‑line jobs exceed recommended ergonomic limits, with high rates of carpal tunnel syndrome and nerve conduction abnormalities among workers.
SPECTRAL IMAGING: A TECHNOLOGY READY FOR POULTRY Spectral imaging has been explored for poultry inspection for more than two decades. Earlier research demonstrated that diseased tissues exhibit distinct reflectance and fluorescence patterns at specific wavelengths. For example: Septicemic livers show measurable differences at 750 nm (visible) and 2300 nm (infrared). Fluorescent spectroscopy can differentiate wholesome carcasses from those with air sacculitis, sep‑tox, or cadaver conditions. Hyperspectral line‑scan systems can classify whole carcasses using hundreds of wavelength channels.

STUDY DESIGN: BRINGING AI AND SPECTRAL IMAGING TOGETHER
70% training, 20% testing, 10% validation Data augmentation applied
Imaging Setup The research team performed twelve imaging sessions between 2022 and 2023. Broiler carcasses identified as sep‑tox or normal by USDA‑FSIS or trained plant personnel were transported to Auburn University. To eliminate ambient light interference, carcasses were photographed inside a custom black polypropylene enclosure using a poultry shackle and a fixed camera stand.

However, these systems have historically been large, expensive, and difficult to integrate into commercial processing lines. The new optical imaging system represents a new generation of portable, multispectral imaging devices designed for real‑time contamination detection in food environments. The Auburn‑USDA study is the first to evaluate its potential for sep‑tox detection.

KEY FINDINGS: HIGH ACCURACY AND VALUABLE INSIGHTS 1

PCA and k‑means clustering identified three distinct clusters among sep‑tox carcasses:
Camera Parameter Optimization Matters
Cluster 1: Paler breast skin, narrower breast shape
Images from early sessions (Setting A) suffered from oversaturation, making sep‑tox carcasses appear unnaturally red and normal carcasses yellow. These images were excluded from final analysis. Setting B produced clearer, more realistic images with better contrast between normal and sep‑tox carcasses.
Processing
2
Unsupervised Clustering Reveals Sep‑Tox Variability
Cluster 2: Deepest red coloration, wider breast frame Cluster 3: Intermediate coloration with red tones on breast and legs Cluster overlap suggests subtle differences in severity or physiological response. This opens the door to grading sep‑tox severity, not just binary classification.
CNN Models Achieved Near‑Perfect Classification Using images from sessions 5–12: Google Colab CNN: 100% accuracy in training, testing, and validation Strong separation between classes Azure Custom Vision: At 50% threshold: 100% precision, recall, and AP
At 85% threshold: • Sep‑tox recall: 96.7% • Normal recall: 96.3% • Precision and AP remained 100% These results indicated that multispectral imaging combined with CNNs can reliably distinguish sep‑tox from normal carcasses under controlled conditions.
IMPLICATIONS FOR POULTRY PROCESSING 1
A Path Toward Automated Sep‑Tox Detection The new optical imaging system demonstrated that: Whole carcasses can be evaluated without physical contact RGB fluorescence imaging is sufficient for classification AI models can achieve high accuracy with relatively simple spectral data
This positions multispectral imaging as a viable candidate for future automated inspection stations.
34 aviNews International September 2026 | Advancing Sep‑Tox Detection: How Multispectral Imaging and AI Could Transform Broiler Carcass Inspection
Supporting Human Inspectors Rather than replacing inspectors, imaging systems could: Reduce fatigue by flagging suspect carcasses Improve consistency across shifts and processing plants Provide objective documentation for regulatory compliance Reduce false positives that lead to unnecessary condemnations
3
Potential for Flock‑Level Health Insights Cluster analysis suggests that sep‑tox presentation varies meaningfully. With further development, processors could: Link spectral signatures to flock health status Identify patterns associated with farm‑level disease pressure
A Promising Step Toward Smarter Inspection The Auburn‑USDA study demonstrates that multispectral imaging paired with machine learning can classify sep‑tox carcasses with exceptional accuracy in controlled environments. While further development is needed to adapt the technology for commercial processing lines, the findings represent a significant advancement in automated poultry inspection. By reducing reliance on subjective visual assessment, processors could improve food safety, reduce ergonomic strain on workers, and minimize unnecessary condemnations. As spectral imaging systems become more robust and AI models more sophisticated, the poultry industry may soon benefit from real‑time, objective, and highly accurate carcass inspection technologies. The future of sep‑tox detection may not be human eyes alone, but a partnership between skilled inspectors, multispectral imaging, and intelligent algorithms.

Challenges Before Commercial Deployment Despite promising results, several hurdles remain: Real‑world variability: Lighting, carcass motion, and orientation differ from lab conditions. Speed: Systems must operate at 140-175 birds per minute without slowing the line.

THE IMPORTANCE OF WATER TO OBTAIN A GOOD START IN THE FIRST WEEK AND HAVE UNIFORMITY AT 7 DAYS OF AGE Hatchery
Winfridus Bakker
In the past, day-old chicks arrived at the farm and only had access to water in the first few hours of placements both in parent stock as in broilers.
Only after several hours of hydration would farm personnel start to distribute feed. Nowadays we do not do this anymore. We have less labor available and want to have all set up when the chicks arrive (easier). What we often see is that farm preparation over emphasize feed but are deficient in water availability. This is due to having the wrong nipples, improper water pressure, incorrect nipple height to mention a few of the main problems. Lack of water availability in the first few hours can cause a considerable delay in chick development visible already by the second day, cause higher mortality due to dehydrated chicks and affect uniformity of the flock.
36 aviNews International September 2026 | The Importance of Water to obtain a Good Start in the First Week and have Uniformity at 7 days of Age
Moreover, the first few hours after placement are very important to educate the chicks, called imprinting, in which the chicks learn quickly. In nature the chicks learn from the mother hen, but in our modern houses we must provide optimal conditions to allow the chicks to mimic what they would learn from the mother hens. Management and preparation conditions are often failing chicks. After the first day, it is more difficult for chicks to find the nipples or take the initiative to find water. In large part, we are losing the battle for an optimal start.
Hatchery
Photo2. Trying to recover these “non-starters” that have not found water is difficult. The development has been minimal, the drinker line is slowly raised based on the size of the normal growing chicks and the result can be an un-uniform flock.
Photo1. A clear difference in development at 2 days of age simply because chicks did not find the water after placement.
Part of the problem of not finding water or having very low water intake is caused by a nipple pin that is not easily activated by day old chicks. There are farms that have the wrong nipples, one that should only be used in production. Others have water pressure problems that inhibit the chick’s ability to drink or a too wide drip cup (only for production) under the nipples instead of a small one (photo 3) interfering with drinking. For farms that reutilize litter, the litter is often not leveled. This causes variation in the distance between the litter and the nipple pin.
Photo3. A cheap support of 9 cm height placed every 3 m to have an even nipple line height in relation to the litter. This support serves only for the 1st day and is basically deactivated when the drinker line is raised slowly. However, the correct height is very important to have high water intake. Calculate max. 40 chicks/nipple.
37 aviNews International September 2026 | The Importance of Water to obtain a Good Start in the First Week and have Uniformity at 7 days of Age
A day-old chick activates the dynamic 360° nipple pin laterally with a beak pressure of 2 to maximum 3 grams. When one observes that lots of chicks die because of dehydration, (and it is more common than many think) there are clear indications that there is not enough water intake for whatever reason.
Hatchery
I have found instances that at one day of age the nipple pins start giving drops of water with a lateral pressure of 4 to 5 grams, meaning chicks either have difficulty or just flat out cannot activate the nipples. Many farms use additional open water cups or water fountains. These systems clearly indicate that the nipple line is not working efficiently or properly to supply water to day old chicks. The proper nipple set-up for rearing parent stock and broilers should work well without any additional open support drinkers.

Graph 1 shows clearly the specifications of a Corti (4006ill) turned nipple. A chick of 32 grams that opens the nipple pin with 2 g of lateral pressure will have a 10 cm water column in the vertical air tube and a water volume of 25 ml/minute. Every company that sells watering nipple equipment should supply the buyer with this type of information so that the nipples can be perfectly adjusted for chicks from 32 to 45 grams.

CONCLUSION Flush the lines and fill with fresh clean water just before the chicks arrive.

have forgotten to give easy access to water. Water intake drives feed intake, not the opposite!
Receive the chicks concentrated between 2 nipple lines 1.5 m apart or around one nipple line to stimulate water intake immediately after placement. The chicks will learn from each other how to activate the nipple pins and personnel could help by activating the nipples and let the noise attract the chicks. Have a lateral pin pressure of 2 g to start the flow of water, whatever the weight of the chicks at arrival. Do not talk and leave the house for 3 hours after placement for chicks to concentrate or imprint on the nipple pins. There should not be any distraction by personnel or other
Chick uniformity problems can be caused by insufficient water intake or simply by chicks struggling to easily activate the nipple pins. Uniformity problems in the first week will extend till the end of a broiler flock and can induce considerable economical loss. In parent stock a much lower uniformity at 7 days will force the need for a grading of the flock. Check the farms and in particular the ones that have uniformity problems, often already visible at 5 to 7 days of age. The problem could be at day of age and more specific in the first few hours after placement related to water intake.

THE STEPS TO ASSURE HIGH WATER INTAKE IN DAY OLD CHICKS SHOULD BE:
noises in the house. Sufficient light intensity (min. 60 lux) at water line level and if possible, only in the area where chicks are received. This keeps them concentrated around the nipple line(s) and the heat source if only local infrared heating is supplied. After 3 hours, check in several places along the nipple line and calculate the % crops with water intake (objective: crops with water between 85% and 100%).

WAYS TO ASSESS THE HATCH WINDOW IN COMMERCIAL HATCHERIES There are several methods to investigate the hatch window in commercial hatcheries. Each of these methods has its specifics and considerations to take into account.

2. Counting hatched chicks at specific times Another method for monitoring the hatch window is to open the hatcher and verify the number of chicks hatched.
3. Analyzing the humidity curve during the hatching phase A third way to monitor the hatch window is by analyzing the humidity curve in the hatcher. The onset of hatching is marked by a rise in humidity as embryos start to externally pip and hatch, releasing moisture into the hatcher environment. This humidity increase continues as more chicks emerge, peaking when the majority have hatched. The shape of the curve reflects how uniformly the hatch has taken place. Petersime uses this principle to monitor the hatch window.
Select at least three hatcher baskets (top, middle and bottom positions) from different locations (e.g. front row, back row, near the wall and near the pulsator).

MITIGATING EARLY CHALLENGES: HOW GENDER SORTING WITH GENESYS STABILIZES UNIFORMITY FROM DAY ONE
Hatchery
CEVA Technical Team
The foundation of a successful broiler operation is laid in the hatchery, where the quality and uniformity of day-old chicks dictate much of the flock’s subsequent performance. Even before chicks arrive at the farm, initial variations can set a trajectory for inconsistency that is challenging
to correct. In this critical early phase, gender sor‑ ting emerges as a pivotal intervention, acting as a powerful tool to mitigate initial challenges and establishing a stable foundation for flock uniformi‑ ty from day one.
46 aviNews International September 2026 | Mitigating Early Challenges: How Gender Sorting with Genesys Stabilizes Uniformity from Day One

Distribution
Supporting data highlights the imperative of this early stabilization. At hatch, factors such as breeder flock age, the hatch window, and incubation environment already contribute to initial weight variation. For instance, eggs from very young or very old breeder flocks can produce chicks with greater initial weight variation. A wide hatch window, where some chicks hatch significantly earlier or later than others, can lead to dehydration in early hatchers and underdevelopment in late hatchers, immediately creating a bimodal weight distribution. However, the most significant driver of early variation, particularly in mixed-sex flocks, is the inherent difference in growth rates and nutritional requirements between male and female broilers. When reared together, faster-growing males often outcompete females for feed, leading to a widening of the Coefficient of Variation (CV%).
Hatchery
and female chicks immediately post-hatch, producers can proactively address the inherent biological differences that, if left unmanaged, would lead to significant variations in growth and development. This early intervention is crucial because a hatchery failure, delivering uneven chicks, makes it nearly impossible to achieve acceptable uniformity levels later, regardless of subsequent management efforts.

Genesys Gender sorting directly counte‑ racts this by eliminating the bimodal wei‑ ght distribution caused by mixed-sex rea‑ ring.

This means that instead of a single, com‑ promised diet and environment attempting to cater to two distinct growth trajectories, each sex can receive precisely what it needs from the outset.

The clear takeaway is that Genesys gender sorting provides a fundamental element for maximizing CV% and is a must-have to unlock the broiler business potential. By addressing the root causes of variation at the earliest possible stage, gender sorting stabilizes flock uniformity from day one, creating a more predictable and manageable production system. This proactive approach not only improves animal welfare but also lays the groundwork for enhanced efficiency, reduced waste, and increased profitability throughout the entire broiler production cycle.

The trial continued with fewer Nick Chick hens (256 birds, 54 cages) and three treatments of varying amino acid levels set at Very Low (VL), Low (L), and High (H). Trial diets were formulated by the H&N nutrition team and produced in a local facility. Raw material analysis was conducted with the support of EVONIK and the diets were a combination of corn, soya bean meal, wheat bran, and soya oil (Table 1).
However, in this trial amount of synthetic amino acids used was increased to six as compared to three in the previous trial.
Diets were formulated to target a 110g feed intake, with energy remaining constant at 2,810 kcal and the ideal protein ratio kept consistent across the three treatments (Table 1).

It is important to understand the cost implications of using all these diets in different scenarios. Based on the cost of feed at the time of the trial and applying the same feed intake, the cost per egg was not significant different (Table 2).

PRACTICAL TAKEAWAYS
CRUDE PROTEIN
AMINO ACIDS DRIVE EGG SIZE
If the intake of crude protein is below certain level, there could be some effect on the productivity of the birds. It seems lower levels of crude protein may boost egg size when combined with synthetic amino acids, however going too low may have consequences for production.
Increasing digestible Lys increased the egg size in the different groups for the second part of the production (57-93 weeks).
EXCESS NITROGEN
As per the literature, we can assume that the nonessential amino acids play a role in egg production that is only influential when diets are excessively low in crude protein.
Feeding hens with low levels of protein and including synthetic amino acids increases amino acid utilization. The amino acid levels formulated in these diets can be used when this combination is applied.
Layers
ECONOMIC BALANCE The increased performance achieved in the High group can reduce the cost of egg production below that of the Low group.
PRODUCTIVITY
SYNTHETIC AMINO ACIDS The performance of the birds didn’t collapse, even at very low levels of crude protein with high levels of synthetic amino acids. This opens the door to the use of local raw materials, so long as the synthetic amino acid price is competitive against the soya bean meal prices.
These results suggest that formulating to such low levels of crude protein could have an impact onproductivity. The impact may not be directly on one production parameter, but may be the sum of several variables that were affected. Therefore, it might be important to define aminimum for Crude Protein when pushing to very low levels. (Check Chapter III).
NUTRITIONAL DISCUSSION AMINO ACIDS DRIVE EGG SIZE
CONCLUSION FOR NICK CHICK SUPPORTERS Nick Chick hens respond positively to different levels of amino acids;
The sensitivity of egg size to amino acid intake in Nick Chick hens is very clear from these results. Therefore, when challenges with achieving egg size arise, one of the first points to examine should be if the birds have a sufficient level of amino acid intake and if this intake is being used for egg production.

The committee report also discusses the growing interest in net energy (NE), which estimates the energy available for metabolism after accounting for heat produced during nutrient utilization.
Dietary Fiber Receives Greater Attention Dietary fiber receives considerably expanded coverage in the new edition. Rather than treating fiber as a single nutritional component, the committee emphasizes that its physiological effects depend on characteristics such as solubility, particle size, lignification, and fermentability. Insoluble fiber supports gizzard development, regulates digesta passage, and improves gastrointestinal function, whereas excessive soluble fiber may impair digestive efficiency. Accordingly,

WORLD’S POULTRY CONGRESS: GLOBAL POULTRY SUSTAINABILITY Edgar O. Oviedo Rondón Prestage Department of Poultry Science, North Carolina State University
Events
The World’s Poultry Congress opened in Toronto just as this edition of AviNews International was going to press. Organized every four years by the branches of the World’s Poultry Science Association since 1921, this year’s Congress brought together 2,093 delegates from 62 countries representing all five continents between July 13 and 16.
The opening plenary session addressed one of modern agriculture’s greatest challenges: meeting the growing global demand for animal protein while protecting environmental, animal, and human health. Bringing together leading scientists from academia, industry, and international organizations, the session demonstrated that sustainability has evolved beyond an environmental objective into a comprehensive strategy encompassing animal welfare, genetics, One Health, precision technologies, and artificial intelligence. Together, the six keynote lectures outlined how poultry production is becoming an increasingly important contributor to global food security.

GLOBAL EXPERTS OUTLINE A NEW VISION FOR POULTRY PRODUCTION The opening session conveyed a clear message: sustainability has become a scientific and strategic imperative rather than simply a corporate initiative. Speakers highlighted the poultry industry’s unique ability to provide affordable, high-quality protein through continuous innovation and exceptional biological efficiency.
Events
Rather than viewing sustainability as a limitation, the presenters described it as an opportunity to improve productivity, strengthen animal welfare, reduce environmental impacts, and build consumer confidence. Throughout the session, sustainability emerged as a multidimensional concept that integrates environmental stewardship, technological innovation, economic viability, public health, and social responsibility.

sustainability initiatives, drawing on experience ranging from corporate programs to national and international sustainability frameworks. She illustrated how coordinated action among industry, researchers, and producers can reshape agricultural systems through science-based decision making. According to Dr. Stackhouse-Lawson, successful programs are built on trusted science, transparent communication, measurable outcomes, and active producer engagement. She emphasized collaborative research models that combine scientific knowledge with practical farming experience instead of relying solely on topdown solutions. These principles now guide Colorado State University’s AgNext program, which develops producer-oriented research designed to address real-world production challenges while improving environmental and economic performance. Her keynote established the framework for the remainder of this opening session by emphasizing innovation, accountability, and collaboration as the foundations of future progress.
Dr. Cheryl M. Stroud, One Health Commission, United States Dr. Cheryl M. Stroud presented One Health as an essential framework for addressing many of today’s interconnected global challenges. She explained that the concept extends well beyond zoonotic diseases by recognizing the close relationships among animals, environmental, and human health. Her presentation demonstrated that issues such as antimicrobial resistance, avian influenza, climate change, biodiversity conservation, food safety, disaster preparedness, zoonotic diseses and soil health cannot be solved within isolated scientific disciplines. Instead, they require coordinated efforts involving veterinarians, physicians, environmental scientists, social scientists, policymakers, producers, and public health professionals. Dr. Stroud emphasized that establishing these partnerships before emergencies arise improves prevention, strengthens response capacity, and contributes to more resilient food systems. She concluded that One Health offers a practical pathway for feeding a global population expected to reach nearly ten billion people by 2050 while protecting ecosystems, improving public health, and strengthening the poultry industry’s social responsibility.

POULTRY’S ROLE IN MEETING FUTURE PROTEIN DEMAND examined how poultry production will help satisfy rapidly growing global demand for animal protein driven by population growth, urbanization, and rising incomes. He noted that poultry already ranks among the world’s most resource-efficient livestock sectors. Decades of advances in genetics, nutrition, housing, health management, and processing have enabled broilers to grow faster with improved feed conversion while allowing commercial layers to produce more eggs over longer production cycles. These biological gains have reduced land, water, and energy requirements while lowering greenhouse gas emissions per kilogram of poultry products. Additional improvements in nutrient recycling, manure management, and circular economy practices are further enhancing resource efficiency.
Looking ahead, Dr. Mitloehner identified precision nutrition, advanced feeding systems, improved biosecurity, disease prevention, environmental monitoring, genetic progress, and climate resilience as key drivers that will allow poultry production to continue expanding while minimizing its environmental footprint. Dr. Mitloehner emphasized that data-driven monitoring tools may help producers optimize housing environments and energy use, while genetic and management improvements support resilience in the face of climate variability.
ANIMAL WELFARE BECOMES CENTRAL TO FUTURE PRODUCTION SYSTEMS Animal welfare was another major theme of the session. Dr. Ingrid de Jong argued that sustainable poultry production cannot be achieved solely by improving productivity or housing conditions. Instead, modern welfare assessment must recognize chickens as stakeholders within production systems by evaluating their behavioral needs and emotional states in addition to health and nutrition.

Dr. de Jong also demonstrated that current welfare assessments often rely on easily measured indicators such as mortality and footpad dermatitis or focus primarily on housing characteristics. Research examples presented by Dr. de Jong showed how lighting programs, environmental enrichment, and behavioral monitoring can provide a more complete understanding of bird welfare. Emerging methods for evaluating both positive and negative emotional states may eventually become part of routine welfare assessments, certification programs, and benchmarking systems. Dr. de Jong also emphasized that routinely collected data can provide important information on welfare, as is demonstrated by an example from the broiler production chain. The value of routine welfare assessment, e.g., for benchmarking and labeling, was briefly discussed.
Advances in molecular biology are rapidly transforming poultry breeding, according to Dr. Huaijun Zhou. He demonstrated how genomics, epigenomics, bioinformatics, and machine learning are accelerating the identification of genes associated with disease resistance, feed efficiency, product quality, animal welfare, and resilience to environmental stress. Beyond identifying favorable genetic variants, researchers are gaining new insight into how nutrition, management, and environmental conditions influence gene expression through epigenetic mechanisms such as DNA methylation and chromatin accessibility. These discoveries are enabling breeding strategies that support healthier birds, reduce antimicrobial use, improve resilience, enhance welfare, and increase production efficiency. Dr. Zhou concluded that integrated genomic and bioinformatic technologies would become increasingly important for maintaining productivity while addressing future production challenges.

Perhaps the most technologically advanced presentation came from Dr. Suresh Neethirajan, who demonstrated how artificial intelligence is transforming poultry production through intelligent sensors, digital twins, machine learning, and advanced computational models. Among the most innovative developments are deep-learning systems capable of interpreting poultry vocalizations with greater than 90% accuracy, providing continuous, non-invasive monitoring of bird behavior, emotional states, and welfare. Digital twin technology combines environmental, visual, acoustic, and physiological information to create virtual representations of commercial flocks. These systems enable producers to optimize housing conditions, anticipate welfare challenges, predict production outcomes, and make management decisions before problems arise.
Artificial intelligence is also supporting climate-smart agriculture through satellite-assisted emission monitoring, carbon accounting platforms, and mobile applications that simplify flock management. Dr. Neethirajan displayed examples of Cluckify and CluckTalk mobile applications, which empower producers through intuitive dashboards and participatory welfare reporting. Together, these technologies are creating a digital ecosystem that integrates welfare science, precision farming, sustainability, and data-driven decision-making into everyday poultry production.
A COMMON MESSAGE ACROSS DISCIPLINES
Events
ARTIFICIAL INTELLIGENCE ENTERS COMMERCIAL POULTRY PRODUCTION
Although each keynote addressed a different scientific discipline, all speakers shared several common conclusions. Future progress will depend on stronger collaboration among researchers, producers, industry, policymakers, and society. Likewise, environmental performance, animal welfare, economic viability, and public health should no longer be viewed as competing priorities but as complementary components of modern poultry production.
The speakers also stressed the importance of transparent data collection, objective scientific measurements, and producer engagement to ensure that technological advances are translated into practical improvements on commercial farms.

A ROADMAP FOR THE FUTURE
Events
The first plenary session made it clear that the poultry industry is entering a new era in which scientific innovation is reshaping every aspect of production. From One Health and animal welfare to genomics, precision agriculture, and artificial intelligence, the speakers presented complementary strategies for producing more food with fewer resources while improving bird health, environmental stewardship, and public confidence. Rather than presenting isolated research findings, this opening session offered an integrated vision of the future in which advanced technologies, interdisciplinary science, and practical collaboration work together to build resilient poultry production systems capable of feeding a growing global population. The session concluded with an optimistic outlook for the poultry sector. Continued investment in research, innovation, and international collaboration will be essential for meeting the dual challenge of increasing food production while protecting natural resources and improving the health and welfare of both animals and people.

During the 27th edition of the World’s Poultry Congress held in Toronto, Canada, the aviNews International team had the opportunity to interview Leticia Orellana, a PhD candidate in Poultry Science from Mississippi State University, with emphasis on poultry reproduction and physiology. Through this interview, the team learned a lot about eggshell translucency, it’s significance in the industry, how to score it and how to prevent it from occurring.

Important Note on Egg Sampling for Shell Translucency: When you collect eggs from a flock to check eggshell translucency, the time of day the eggs were laid makes a big difference. The same flock can show very different results depending on when the eggs are picked up. In a recent study with Cobb500 birds, we found: •
Eggs laid in the morning (around 9:00 a.m.) had only about 10% with high translucency.
•
Eggs collected in the afternoon (around 2:00 p.m.) had about 50%

with high translucency. This means that if for sampling you mostly use eggs that were laid in the afternoon, you may think the flock has a much bigger translucency problem than it actually does.
Is eggshell translucency related to other eggshell quality parameters? Yes. Our research has shown that eggshell translucency is associated with other important shell quality traits, particularly shell thickness and shell strength. One of the most interesting findings is that eggs with higher translucency often have thicker and stronger shells. At first glance, this may seem like a positive characteristic, since the poultry industry has traditionally considered thick, strong shells to be indicators of good egg quality. However, our results also show that these highly translucent eggs tend to have lower hatchability. This suggests that a thicker or stronger shell does not

How to prevent or reduce eggshell translucency? So far, our research has focused on describing eggshell translucency, understanding how it is influenced by flock age and time of oviposition, and how it relates to other eggshell quality parameters. We have also demonstrated its value as a simple, non-destructive indicator of hatchability.
These published studies have shown promising results in improving and reducing the incidence of highly translucent eggs. However, additional research is still needed to fully understand how eggshell translucency develops, what factors contribute to its occurrence, and how it can be effectively managed under commercial production conditions.

Based on the available literature, most of these studies have focused on nutrition and flock management practices. Some of the strategies that have been investigated include: Improving calcium and phosphorus metabolism Supplementing trace minerals, such as zinc, manganese, and copper, especially in organic forms Optimizing vitamin D levels Evaluating specific calcium sources, suchx as monodicalcium phosphate (MDCP) Reducing heat stress through proper house temperature, humidity control, and avoiding overcrowding
