Every day, a broiler’s intestine processes several times its body weight in feed and water, encounters billions of microorganisms, responds to environmental stress, and continuously decides what enters the body and what remains outside.

In many ways, the gut functions as a customs checkpoint, security system, digestive factory, and immune headquarters—all at the same time.

In fact, nearly 70% of the bird’s immune cells are associated with the gastrointestinal tract, making it a key player in both health and performance. The remarkable aspect is that when the gut is functioning well, nobody notices it. When it begins to fail, everybody notices the consequences.

The Modern Poultry Bird: Built for Speed
Today’s broiler is a biological marvel. Through decades of genetic selection, modern birds reach market weight faster and more efficiently than ever before.
However, this achievement comes with a hidden challenge.

The digestive tract has become one of the most critical performance-limiting organs in poultry production. Every gram of feed must be digested, absorbed, and converted into muscle within an increasingly compressed production cycle.

Twenty years ago, a small reduction in nutrient absorption might have gone unnoticed. Today, even minor intestinal inefficiencies can translate into measurable losses in body weight gain, feed conversion ratio, and profitability. Modern birds can no longer afford a lazy gut.

The Gut Is Constantly Making Decisions
Traditionally, we think of the intestine as a nutrient absorption organ.
In reality, the gut is making thousands of biological decisions every second.

– Should nutrients support growth or immunity?
– Should a microorganism be tolerated or eliminated?
– Should energy be invested in production or defense?
– Should the intestinal barrier remain open for absorption or tighten to prevent invasion?

These microscopic decisions ultimately determine flock performance.
In many ways, poultry production is not simply about feeding birds—it is about influencing the decisions being made within the gut.

The Hidden Cost of Inflammation
One of the most important concepts emerging in poultry science is that inflammation carries a nutritional cost.
Whenever the intestine encounters stress from pathogens, mycotoxins, heat, poor litter quality, or microbial imbalance, the immune system becomes activated.
The immune response is essential for survival, but it is expensive.
Energy that could support growth is redirected toward immune activity.
Amino acids that could build muscle are utilized to produce immune proteins and inflammatory mediators.
Vitamins and minerals become involved in tissue repair and antioxidant defense.
The bird continues eating, yet a significant proportion of nutrients may no longer be contributing to production.
This phenomenon is often referred to as the “hidden feed cost” of inflammation.

The Silent Performance Thief
One of the greatest misconceptions in poultry production is that intestinal problems always produce visible symptoms.
– Not necessarily.
– Many flocks show normal feed intake, acceptable mortality, and no obvious disease outbreaks. Yet they consistently fail to achieve target performance.
– A slight reduction in nutrient absorption.
– A minor microbial imbalance.
– A low level of intestinal inflammation.
– A subtle increase in intestinal permeability.
Individually these changes may appear insignificant. Collectively they can result in substantial economic losses. This is why gut health is increasingly viewed not as a disease issue but as a performance issue.

The Microbial Workforce Inside Every Bird
Perhaps the most fascinating discovery in recent years is the realization that birds are never truly alone.
The digestive tract contains trillions of microorganisms collectively known as the gut microbiome.
These microbes help digest feed ingredients, produce beneficial metabolites, support intestinal development, influence immune responses, and compete with harmful bacteria.
Some scientists now describe the microbiome as an additional organ because of its profound influence on bird health.
This raises an interesting question:
Are we feeding the bird, or are we feeding its microbiome?
The answer is both.
The future of poultry nutrition may depend as much on managing microbial populations as on balancing nutrients.

Heat Stress: The Gut’s Greatest Enemy
In many poultry-producing regions, heat stress has become one of the most significant challenges affecting gut health.
High environmental temperatures reduce blood flow to the intestine, increase oxidative stress, and compromise intestinal barrier integrity.
As a result, harmful bacterial toxins can cross the intestinal wall and trigger inflammation.
Often the first casualty of heat stress is not growth—it is gut integrity.
This may explain why heat-stressed flocks frequently show poorer FCR, increased wet litter, reduced nutrient utilization, and greater disease susceptibility.
As global temperatures continue to rise, protecting gut health during periods of heat stress will become increasingly important.

The Gut in the Antibiotic-Free Era
The poultry industry is rapidly transitioning toward antibiotic-free and reduced-antibiotic production systems.
While this shift addresses consumer concerns and regulatory requirements, it has also increased attention on intestinal health.
Without routine antibiotic growth promoters, producers must rely on alternative strategies to maintain gut stability.
Probiotics, prebiotics, β-glucans, mannan oligosaccharides (MOS), organic acids, phytogenic compounds, and postbiotics are increasingly being used to support intestinal resilience and microbial balance.
The focus is shifting from killing pathogens to creating an intestinal environment where beneficial microbes and the host can thrive together.

More Birds or More Protein?
The global poultry industry is not being asked to produce more birds.
It is being asked to produce more protein.
As the world’s population grows and consumers increasingly seek affordable animal protein, poultry production continues to expand. Industry projections estimate the sector will grow at a CAGR of approximately 5–7% over the coming years.

But growth alone is not enough.
Producers are expected to deliver more meat with fewer resources, lower feed costs, and a smaller environmental footprint.
This means that every gram of feed matters more than ever before.
And that brings us back to the gut.
Because the difference between feed consumed and protein produced is ultimately determined by the efficiency of the digestive system.

The Future Begins in the Gut
For decades, poultry production focused on genetics, nutrition, and disease control.
The next frontier may be intestinal resilience.
Future improvements in productivity will likely come from better management of inflammation, enhanced barrier integrity, optimized microbiomes, and improved nutrient efficiency within the gastrointestinal tract.
The question may no longer be:

“How much feed did the bird consume?”

Instead, the more important question may be:
“How much of that feed actually became growth?”
The answer lies within the gut.
Not because it is merely another organ, but because it is the organ that determines how effectively all the others perform.
In an era of narrow margins, rising feed costs, heat stress, and antibiotic-free production, the healthiest gut may ultimately become the most valuable asset in the poultry house.

PIONEERING ANIMAL HEALTH THROUGH PHYTOGENIC INNOVATION

France Based IDENA’s Complex Phytogenic Animal Nutrition Products Through Feed Development has led to Higher Productivity and Better Animal Health – Ricky Thaper (www.rickythaper.com)

Improving livestock health has been recognized by producers as an important sustainability effort which improves efficiency and reduces productivity losses in the animal husbandry sector. The United Nations Food and Agriculture Organisation (FAO) has urged nations to integrate animal health into their national climate commitments, calling it “vital for sustainable livestock production.” The roadmap recognized the importance of livestock to 1.7 billion farmers worldwide and offered proven pathways for addressing its climate footprint including better genetics, feed, and animal health. An UN report calculated the effects of different steps to address livestock emission by stating that animal productivity increase would reduce emissions 20%. It also stated that feed improvements by 12%, better animal health by 10%, improved genetics by 8% and methane reducing feed additives by 5%.

This growing recognition of the value of animal health and related technologies has the potential to boost livestock sustainability and decrease its carbon footprint. This will require adoption of strong biosecurity protocols, improved feed and use of good additives, better breeding practices and adoption of new digital technologies. Keeping this vision in mind, several companies have been working towards boosting animal health and productivity through development of innovative products keeping into consideration the unique needs of countries across the world.

Since its creation in 1995, France based global major in animal nutrition IDENA group has developed products keeping into account the nutritional needs of poultry, dairy, and piggery. The key focus of the IDENA is to introduce innovative additives and pre-mixes which boost the poultry and livestock feed and increase performances of poultry and livestock in the farms.

At IDENA, head-quartered in SAUTRON, Pays de la Loire, France, there are experts who are passionate about developing products which promote animal growth and welfare. IDENA’s technical and sales teams, often in the field, offers tailor-made advice to improve the formulation of products and optimise their effectiveness depending on the needs of the customer. The company has succeeded in establishing its fundamentals and convictions in the animal nutrition market, developing them and continuing to build on them. In 2001, the IDENA production plant in Pontchâteau, France was set up.

The mission of the company is to market natural alternatives to conventional additives in order to reduce the use of antibiotics and preserve their effectiveness (antibiotic resistance). These alternatives are made up of phytogenic, bioactive and active ingredients derived from lactic fermentations through IDENA’s sister company STI BIOTECHNOLOGIE which has developed a unique range of Postbiotics.

Following a specific inactivation process, STI Biotechnologie manufactures, among other products, a postbiotic solution, available in powder and liquid form. METALAC promotes digestive comfort, enhances animal welfare, and improves the animals’ immune status.

The company has numerous scientific publications: S. Jansseune’s thesis, published last June, expanded knowledge of METALAC through in vitro and in vivo experimental trials, as well as on the composition of metabolites synthesized during bacterial fermentation. The postbiotic contributes to the formation of a beneficial bacterial biofilm to protect intestinal villus cells, thereby strengthening the intestinal barrier. This research is continuing with a postdoctoral fellowship in collaboration with the University of Rennes, supervised by Monogastric Product Manager Maeva JEGOU.

Under the leadership of Director Christophe TANGUY, the Asia-Middle East region is managed by David CHEREL, based in China.

IDENA has also developed a complete range of nutritional specialities to improve the feed efficiency of animals fed in organic farming systems and these products are all approved by official organic farming certification bodies.

IDENA has a range of poultry products, among them; FORCIX PY (Prevention of the risk associated with Eimeria together with Necrotic Enteritis), FORKEY LS (Prevention of the risk associated with Histomonas in Turkeys), EVOPERF (Digestive comfort and performance), PONTIPLUS (Supporting hen productivity and longevity by maintaining laying rate and improving egg quality and breeders’ eggs hatchability) and IDAFIX+ (a large spectrum powerful mycotoxin binder). All these poultry products are based on the results of extensive scientific research, particularly into the action of plant extracts and essential oils. The issues studied relate mainly to make better use of the nutrients supplied and managing the risks of parasites and bacteria amongst the poultry birds. In poultry, IDENA focus is on gut health, mineral balance, feed efficiency, and resilience of birds under commercial conditions. IDENA solutions combine R&D, field validation, and practical formulation expertise to ensure both technical efficiency and economic viability. The nutrition experts in the company have developed a range of products designed to improve the feed efficiency of ruminants, focussing on critical components – protein, energy and fibre.

Introduction
The poultry industry is one of the fastest-growing segments of global agriculture and plays a crucial role in ensuring food security, nutritional sustainability, and rural livelihoods. Poultry meat and eggs are among the most affordable and widely consumed sources of high-quality animal protein. However, the economic sustainability of poultry farming is increasingly threatened by rising feed costs, which account for nearly 65–75% of total production expenditure in commercial poultry enterprises. Among feed ingredients, soybean meal (SBM) constitutes the primary protein source because of its superior amino acid profile, high digestibility, and consistent nutrient availability. Nevertheless, volatility in soybean prices due to climate change, global trade disruptions, geopolitical conflicts, biofuel competition, transportation costs, and fluctuating international commodity markets has significantly increased production costs in poultry farming. The dependence on imported soybean meal in many developing countries, including India, further exposes poultry producers to supply chain uncertainties and foreign exchange fluctuations. Consequently, poultry nutritionists and farm managers are actively exploring alternative protein sources and innovative farm management strategies to reduce feed costs while maintaining productivity, flock health, and profitability. Simultaneously, advances in precision poultry farming, digital technologies, environmental control systems, and feed efficiency optimization are transforming poultry production into a more data-driven and economically resilient enterprise. The integration of nutritionally viable soymeal alternatives with smart farm management practices offers a promising pathway toward sustainable poultry production under conditions of escalating feed prices.

Importance of Soybean Meal in Poultry Nutrition
Soybean meal has long been regarded as the benchmark protein ingredient in poultry diets because of its excellent nutritional characteristics. Typically containing 44–48% crude protein, soybean meal provides an ideal balance of essential amino acids, particularly lysine, which is often limiting in cereal-based diets. Its high digestibility, palatability, and relatively low fibre content make it highly suitable for broilers, layers, breeders, and turkeys.
In broiler nutrition, soybean meal supports rapid muscle development, efficient feed conversion, and improved carcass quality. In layer production, it contributes to enhanced egg production, egg mass, and shell quality. Furthermore, soybean meal contains beneficial bioactive compounds and functional peptides that positively influence gut health and immune responses.

Despite these advantages, excessive dependence on soybean meal has created several challenges for the poultry industry. Global soybean production is concentrated in a limited number of countries, making supply chains vulnerable to climatic events, geopolitical instability, and export restrictions. Additionally, soybean cultivation has been associated with deforestation, biodiversity loss, and environmental concerns, especially in South America. Increasing competition between feed, food, and biofuel sectors has also intensified pressure on soybean availability and pricing.

As feed costs continue to rise, the poultry industry is increasingly compelled to diversify protein sources and adopt more economically sustainable feeding strategies.

Economic Consequences of Rising Feed Cost in Poultry Production
Feed cost inflation directly reduces profit margins in poultry enterprises. Since poultry production operates on relatively narrow economic margins, even modest increases in feed prices can significantly affect profitability. Broiler production is particularly sensitive because of short production cycles and high feed consumption rates. Similarly, in layer operations, prolonged periods of elevated feed prices may substantially reduce returns over feed cost.

Rising feed costs result in several economic consequences:
– Increased cost per kilogram of live weight gain.
– Reduced feed conversion efficiency under poor-quality diets.
– Decline in egg production profitability.
– Increased market price of poultry products.
– Reduced competitiveness of small-scale producers.
– Lower farm expansion and investment capacity.

In many regions, feed manufacturers and poultry producers respond by reformulating diets with lower-cost ingredients. However, indiscriminate replacement of soybean meal without proper nutritional balancing may impair growth performance, immunity, carcass quality, and reproductive efficiency. Therefore, economically sustainable poultry production requires a scientific approach that combines alternative feed ingredients with precision nutritional management.

Oilseed Meals as Alternatives to Soybean Meal
Oilseed by-products are among the most practical alternatives to soybean meal in poultry feeding systems. Several oilseed meals possess substantial protein content and can partially replace soybean meal when diets are appropriately formulated.

Canola Meal
Canola meal contains approximately 35–40% crude protein and is rich in sulphur-containing amino acids. It can effectively replace part of soybean meal in broiler and layer diets. However, its higher fibre content and presence of glucosinolates may limit inclusion levels.

Sunflower Meal
Sunflower meal is another important protein source with good methionine content. Dehulled sunflower meal possesses improved nutrient density and can be used efficiently in poultry rations. Enzyme supplementation enhances its digestibility.

Cottonseed Meal
Cottonseed meal provides substantial protein but contains gossypol, a toxic pigment that restricts its inclusion in poultry diets. Proper processing and iron supplementation may reduce toxicity concerns.

Groundnut Cake
Groundnut cake is widely used in India and other Asian countries because of its local availability and moderate protein content. However, aflatoxin contamination remains a major concern requiring strict quality control measures.

Sesame and Linseed Cakes
These oilseed cakes provide supplementary protein and beneficial fatty acids, although their use is often limited by fibre content and anti-nutritional factors. Oilseed meals can substantially reduce feed costs when incorporated scientifically with amino acid balancing and enzyme supplementation.

Use of Legume Grains in Poultry Feeding
Legume grains are gaining popularity as sustainable and locally available protein alternatives in poultry nutrition. Commonly used legumes include peas, lupins, chickpeas, pigeon pea, and faba beans.
Nutritional Advantages
– Moderate to high protein content.
– Good starch availability.
– Reduced dependence on imported soybean meal.
– Nitrogen fixation benefits in agriculture.
– Lower environmental footprint.

Constraints
– Presence of tannins, trypsin inhibitors, lectins, and non-starch polysaccharides.
– Lower methionine content compared to soybean meal.
– Variability in nutrient composition.

Modern processing technologies such as extrusion, roasting, soaking, dehulling, and fermentation help reduce anti-nutritional factors and improve nutrient utilization. In broiler diets, partial replacement of soybean meal with processed legumes has demonstrated satisfactory growth performance and feed efficiency.
The use of locally cultivated legumes can also strengthen regional feed security and reduce transportation-related costs.

Distillers Dried Grains and Agro-Industrial By-Products
Agro-industrial by-products represent an economically valuable resource for poultry feeding. The poultry industry increasingly utilizes these ingredients within circular economy models aimed at reducing waste and improving resource efficiency.

Distillers Dried Grains with Solubles (DDGS)
DDGS is a by-product of ethanol production and contains considerable protein, fat, phosphorus, and digestible energy. It is widely used in broiler and layer diets at moderate inclusion levels.
Rice Bran
Rice bran is abundantly available in rice-producing countries and provides energy, oil, vitamins, and moderate protein. Stabilization is necessary to prevent rancidity.
Wheat Bran and Pollard
These by-products supply fibre, phosphorus, and moderate protein but are generally used at lower inclusion rates in poultry because of high fibre levels.
Brewer’s Grains
Brewer’s grains can serve as low-cost feed ingredients after proper drying and preservation.
Bakery Waste
Processed bakery waste offers a highly digestible energy source capable of partially replacing maize in poultry diets. Although agro-industrial by-products reduce feed costs, variability in nutrient composition necessitates routine laboratory analysis and quality assurance.

Insect Meal as a Novel Protein Source
Insect meal has emerged as a highly promising alternative protein source for poultry production. Black soldier fly larvae meal, mealworm meal, and housefly larvae meal possess high crude protein levels and favourable amino acid profiles.

Advantages of Insect Meal
– Excellent digestibility.
– High protein concentration.
– Efficient conversion of organic waste into biomass.
– Reduced land and water use.
– Lower environmental impact compared to soybean cultivation.

Studies have shown that insect meal can partially replace soybean meal and fishmeal in broiler diets without adversely affecting growth performance or carcass quality. Some insect-derived lipids also possess antimicrobial properties that may support gut health.

However, large-scale commercialization faces several limitations:
– High production costs.
– Regulatory constraints.
– Limited industrial infrastructure.
– Consumer perception challenges.
As production technologies improve, insect meal may become increasingly competitive as a sustainable protein source for poultry feeding.

Algae, Single Cell Proteins, and Fermented Feed Ingredients
Microalgae and microbial proteins represent future-oriented feed resources with substantial potential for poultry nutrition.

Microalgae
Species such as Spirulina and Chlorella contain high-quality protein, essential fatty acids, vitamins, minerals, and pigments. In layer diets, algae supplementation enhances yolk pigmentation and antioxidant status.
Single Cell Protein (SCP)
Yeast, bacteria, and fungal biomass can provide highly digestible protein with rapid production rates and minimal land requirement.
Fermented Feed Ingredients
Fermentation improves nutrient availability and reduces anti-nutritional compounds in feed ingredients. Fermented soybean meal, fermented legumes, and probiotic-enriched feeds enhance gut health and nutrient absorption in poultry.

These technologies contribute to improved feed conversion efficiency and may reduce dependence on expensive conventional protein sources.

Precision Nutrition and Least-Cost Feed Formulation
Precision nutrition is essential for maintaining profitability during periods of feed cost escalation. Modern least-cost formulation software allows nutritionists to design diets that meet nutrient requirements at minimum cost while incorporating alternative ingredients.

Major Precision Nutrition Approaches
– Digestible amino acid formulation.
– Ideal protein concept.
– Phase feeding.
– Precision protein nutrition.
– Net energy systems.
– Use of synthetic amino acids.

The supplementation of lysine, methionine, threonine, valine, and tryptophan enables significant reduction in crude protein levels without compromising performance. Lower protein diets reduce feed cost, nitrogen excretion, and metabolic stress.

Feed enzymes such as phytase, xylanase, protease, and β-glucanase further enhance nutrient digestibility and improve utilization of unconventional feed ingredients.

Precision nutrition therefore represents a cornerstone strategy for economical poultry production under volatile feed markets.

Smart Feeding Systems and Feed Wastage Reduction
Feed wastage significantly contributes to economic losses in poultry farming. Smart feeding technologies help optimize feed distribution, minimize wastage, and improve feed efficiency.

Important Smart Feeding Technologies
– Automated feeding systems.
– Sensor-based feed dispensers.
– Precision feed allocation systems.
– Real-time feed intake monitoring.
– Smart silos and inventory systems.
Automated systems ensure uniform feed distribution and reduce labour dependency. Sensor technologies can detect abnormal feed consumption patterns, enabling early identification of health or management problems.

Proper feeder design, adjustment of feeder height, and prevention of feed spillage also play important roles in minimizing wastage. Even small reductions in feed wastage can substantially improve farm profitability during periods of high feed prices.

Environmental Control and Poultry House Management
Environmental management strongly influences feed intake, nutrient utilization, and overall poultry performance. Poor environmental conditions reduce growth rate, impair immunity, and worsen feed conversion efficiency.

Critical Environmental Factors
– Temperature.
– Humidity.
– Ventilation.
– Air quality.
– Lighting programs.
– Litter management.

Heat stress is particularly detrimental in tropical and subtropical poultry production systems. Birds exposed to high temperatures reduce feed intake, resulting in lower body weight gain and egg production.

Modern environmentally controlled poultry houses utilize:
– Tunnel ventilation.
– Evaporative cooling systems.
– Automated climate control.
– Smart sensors for temperature and humidity monitoring.
These systems help maintain optimal environmental conditions, improve bird comfort, and enhance feed efficiency.

Gut Health Management and Feed Efficiency
Maintaining optimal gut health is essential for efficient nutrient utilization and profitability in poultry production. Intestinal health directly affects digestion, absorption, immunity, and feed conversion efficiency.

Key Gut Health Strategies
– Probiotics.
– Prebiotics.
– Organic acids.
– Phytogenic feed additives.
– Enzymes.
– Competitive exclusion products.

The reduction in antibiotic growth promoter usage has increased the importance of alternative gut health management approaches. Healthy intestinal microflora improves nutrient digestibility and reduces disease susceptibility.

Mycotoxin management is equally critical because contaminated feed ingredients can impair gut integrity, suppress immunity, and reduce productivity. The use of toxin binders and strict feed quality control helps maintain flock performance under challenging feeding conditions.

Digital Technologies and Precision Poultry Farming
Precision poultry farming integrates digital technologies, automation, sensors, artificial intelligence, and data analytics to optimize poultry production efficiency.

Applications of Precision Poultry Farming
– Real-time flock monitoring.
– Automated mortality detection.
– Feed and water consumption analysis.
– Environmental monitoring.
– Predictive disease surveillance.
– Behavioural analysis using cameras and sensors.

Artificial intelligence-based systems can identify deviations in flock behaviour before visible clinical signs appear. Early disease detection reduces mortality losses and treatment costs.

Cloud-based management platforms allow integration of production, nutrition, health, and financial data for better decision-making. Data-driven management improves resource utilization and supports economic sustainability.

Sustainability and Climate-Resilient Poultry Production

Sustainable poultry production requires balancing economic profitability with environmental responsibility. Rising feed costs and climate-related disruptions highlight the need for resilient feeding systems and efficient resource utilization.

Important Sustainability Strategies
– Diversification of feed ingredients.
– Use of locally available feed resources.
– Circular economy approaches.
– Reduction of feed carbon footprint.
– Water conservation.
– Renewable energy utilization.

Climate-smart poultry production systems emphasize resilience against heat stress, feed shortages, disease outbreaks, and market volatility. Alternative proteins such as legumes, insect meal, algae, and agro-industrial by-products contribute to greater feed system sustainability.

The integration of smart technologies further improves resource efficiency and environmental performance.

Way Forward
Rising feed costs represent one of the most significant challenges confronting modern poultry production systems. Since soybean meal remains a major contributor to feed expenses, reducing dependency on conventional soybean-based diets has become an economic necessity for poultry producers worldwide. A wide range of alternative protein sources—including oilseed meals, legumes, agro-industrial by-products, insect meal, algae, microbial proteins, and fermented feed ingredients—offer considerable potential for reducing feed costs while maintaining productive performance.

However, successful incorporation of soymeal alternatives requires scientific feed formulation, proper ingredient processing, amino acid balancing, quality control, and strategic use of feed additives and enzymes. No single alternative ingredient can completely replace soybean meal under all production conditions; therefore, diversified and flexible feeding programs are essential.

Equally important is the adoption of smart farm management systems that improve feed efficiency and operational sustainability. Precision nutrition, automated feeding systems, environmental control technologies, gut health management, digital monitoring platforms, and artificial intelligence-based decision support systems can substantially enhance profitability during periods of volatile feed prices.

The future poultry industry will increasingly depend on the integration of alternative feed resources with precision poultry farming technologies. Producers capable of combining nutritional innovation, smart management, and sustainability-oriented practices will be better positioned to withstand economic uncertainties and maintain long-term profitability. Thus, exploring soymeal alternatives alongside intelligent farm management is not merely a temporary response to rising feed costs, but a strategic transformation toward resilient, efficient, and sustainable poultry production systems for the future.

– Dr Andreas Lewke

Ricky Thaper: What makes Dr. Eckel’s solutions particularly relevant for poultry producers in a market like India?
Dr. Andreas Lewke: In many markets, advanced feed additives are sometimes still seen as “nice to have” products. Our experience in Asia shows that, under today’s competitive conditions, they are much more than that: in fact, they are important tools for securing performance and profit.

Our phytogenic products support gut health, feed efficiency and overall robustness of the birds, whether by helping them cope with stress, pathogen pressure or by diminishing the burden of endotoxins. Together, these concepts help producers to get more value from every kilogram of feed, to stabilise performance under challenging conditions and to protect product quality, while supporting strategies to reduce the reliance on antibiotics and to respond to customer expectations for safe, high-quality poultry meat and eggs. We know that Indian poultry professionals already run very sophisticated operations. Our goal is to offer solutions that fit into these systems and add measurable value where it matters most.

Ricky Thaper: Could you tell us a bit about your own role and background?
Dr. Andreas Lewke: I am Managing Director of Dr. Eckel Animal Nutrition in Thailand and responsible for our activities in Asia. I have been working in the region for more than 20 years, always in the field of animal nutrition and feed additives. Over the years I have worked closely with integrators, feed mills and farmers across Asia. My main interest is how innovative, sustainable nutrition concepts can support both healthy animals and healthy profits.

Ricky Thaper: How do you see your connection to the Indian poultry sector in particular?
Dr. Andreas Lewke: India is a key part of our Asian focus. The scale, professionalism and speed of development in the Indian poultry industry are impressive. Over the years I have had many discussions with Indian colleagues at conferences and during customer visits in the region.

What I see is a very strong base of local expertise and entrepreneurial spirit. Indian poultry professionals are highly knowledgeable and very open to new ideas, but they rightly expect clear evidence and practical benefits. They ask tough, practical questions: does it work in my conditions, is it economic, does it help me secure my business in the long run? This mindset fits very well with how we work at Dr. Eckel.

Ricky Thaper: From your perspective, how would you describe the Indian poultry industry today – its strengths and its main challenges?

Introduction
Insoluble fiber has gained increasing recognition in modern poultry nutrition due to its physiological importance, impact on digestive health, nutrient utilization, and welfare outcomes in birds. Unlike soluble fiber, which is rapidly fermented and increases digesta viscosity, insoluble fiber adds bulk, optimizes intestinal motility, and influences digesta structure to facilitate more efficient nutrient digestion and absorption.

Composition and Characteristics
Insoluble fiber primarily consists of cellulose, hemicellulose, and lignin—structural plant components resistant to hydrolysis by poultry endogenous enzymes. As it passes largely intact through the gastrointestinal tract (GIT), its physiological effects are exerted mainly through physical stimulation of digestive processes and organs rather than fermentation.

Mechanisms of Action
The activity of insoluble fiber in poultry nutrition is mediated through multiple mechanisms. Due to its indigestible nature, insoluble fiber accumulates in the gizzard, enhancing muscular development and function, thereby facilitating mechanical feed breakdown and improved efficiency of nutrient digestion. Moderate inclusion levels (1–2%) accelerate digesta passage, reduce retention of toxic metabolites, and enhance intestinal health. Insoluble fiber stimulates secretions of amylase, lipase, and protease, thereby improving starch, protein, and fat digestibility. Inclusion supports favorable intestinal morphology, such as increased villus height and crypt depth, contributing to enhanced absorptive capacity. Microbial Modulation: Insoluble fiber fosters a balanced gut microbiota by modifying the luminal environment and limiting pathogen proliferation.

Physiological and Welfare Outcomes
The presence of insoluble fiber in poultry diets exerts several measurable outcomes:
– Enhanced gizzard and proventriculus growth, supporting feed utilization efficiency.
– Faster intestinal transit, minimizing toxin accumulation.
– Improved litter quality and reduced wet litter incidence.
– Behavioral benefits, including amelioration of cannibalism and improved satiety, particularly in layers.

Metabolic Effects and Excretion
Metabolically, insoluble fiber is minimally fermented in the caeca, with its primary influence derived from physical and physiological stimulation. Notable outcomes include:
– Enhanced pancreatic enzyme secretion, improving nutrient extraction.
– Improved intestinal morphology that augments nutrient absorption.
– Increased bulk volume of excreta with improved consistency, resulting in firmer, drier droppings.
– Reduced ammonia generation and improved hygiene, thereby lowering infection risks in poultry houses.
Sources of Insoluble Fiber
Historically, wheat bran and rice bran have been common fiber sources due to their high cellulose content and cost-effectiveness. However, their susceptibility to mycotoxin contamination has prompted a transition to safer alternatives:

– Agricultural By-products: Oat hulls, soybean hulls, sunflower hulls, and pea hulls now serve as reliable fiber sources with high inclusion potential.
– Purified Products: Commercial lignocellulose concentrates provide mycotoxin-free, standardized fiber inclusion with improved reliability.
– Other Sources: Rice hulls and wood shavings add bulk, contributing positively to litter quality, nutrient absorption, and predator-prevention behavior (e.g., reduced cannibalism).

Comparative Nutritional Profiles
Wheat and rice bran remain cost-effective and commonplace, though often limited to below 5% of the diet because of contamination risks. Soybean and sunflower hulls offer high crude fiber and moderate protein, while oat hulls excel in stimulating digestive organs. Lignocellulose offers the highest concentration of insoluble fiber with the lowest contamination risk and greatest consistency.

Performance Outcomes
Recent Indian studies (2024) demonstrated that the inclusion of 2.5% soybean hulls or lignocellulose in broiler diets improved body weight gain (BWG) and feed conversion ratio (FCR). Similarly, rice hull supplementation has been associated with increased gizzard weight without adverse effects on carcass yield, validating the importance of insoluble fiber for digestive organ development and growth performance.

Strategies to Manage Soluble and Insoluble Fiber Levels
The key to successful fiber management lies in achieving optimal ratios. Research demonstrates that moderate levels of insoluble fiber (3-5% of diet) can actually enhance nutrient digestibility by stimulating digestive organ development and pancreatic enzyme secretions, while excessive soluble fiber levels create viscosity problems that impair performance.

1) Cost-Effective Fiber Source Selection
Primary Insoluble Fiber Sources
Wheat bran remains the most economical insoluble fiber source, providing 44.6 % fiber content. It offers excellent laxative properties when mashed with warm water and helps maintain optimal litter moisture.

Rice bran represents another cost-effective option, delivering 10-14% protein alongside 20-24% total dietary fiber and 10.4 MJ ME/kg energy content. This dual nutrient contribution makes rice bran particularly valuable for achieving both fiber and protein targets.
De-oiled rice bran (DORB) provides concentrated fiber benefits with reduced oil content, making it suitable for higher inclusion rates without compromising pellet quality.

Alternative Fiber Sources
Sunflower hulls and oat hulls offer concentrated insoluble fiber sources that require minimal inclusion levels to achieve desired fiber targets. These sources are particularly valuable when formulating high-energy density diets where traditional bran sources would excessively dilute nutrient concentration.

Soy hulls contain approximately 36% crude fiber and 10% crude protein, making them excellent fiber sources for ruminants but requiring careful consideration in poultry diets due to potential bloating risks.

2) Enzyme-Based Fiber Management Strategies
Single Enzyme Approaches
Xylanase supplementation at 16,000-32,000 BXU/kg has proven highly effective for managing arabinoxylans, particularly in wheat-based diets.
Research demonstrates that double-dose xylanase (32,000 BXU/kg) provides superior NSP degradation and oligosaccharide release compared to standard doses.
Studies with de-oiled rice bran supplementation show that xylanase at 10g/100kg feed improved body weight gain and feed consumption while reducing mortality rates compared to high-fiber control diets. The enzyme enabled profitable utilization of 4.5% crude fiber levels, with net profit per kg body weight gain being highest in the maximum fiber plus xylanase treatment.
Multi-Enzyme Complex Systems
Carbohydrase-protease-phytase combinations demonstrate additive beneficial effects, particularly in nutritionally marginal diets. Combined enzyme supplementation can improve body weight gain by 14% compared to individual enzyme use (6-7% improvement). This synergistic effect results from:
– Enhanced protein and amino acid digestibility through protease action
– Improved phosphorus availability via phytase activity
– Better carbohydrate utilization through NSP-degrading enzymes
– Reduced anti-nutritional factor impacts

NSP-degrading enzyme cocktails containing xylanase, β-glucanase, cellulase, pectinase, mannanase, galactanase, and arabinofuranosidase show variable results depending on substrate composition. While effective for complex fiber matrices, they require precise matching to dietary NSP profiles for optimal performance.

3) Feed Formulation Strategies for Cost Reduction
Matrix Value Application
Enzyme supplementation enables matrix value attribution, allowing nutritionists to reduce expensive ingredients while maintaining performance. Effective enzyme programs can provide energy matrices of 100+ kcal/kg, enabling significant reformulation flexibility.

Precision Nutrition Approaches and Fiber Level Management
Daily nutrient blending using a two-concentrate system, where a high-protein starter concentrate is diluted with a high-energy finisher concentrate, can improve feed conversion ratio by 7.8% while reducing feed costs by 4.13%. During the starter phase (0–10 days), diets should include minimal fiber (2–3% crude fiber) to maximize nutrient density and digestibility for critical early growth. In the grower phase (11–24 days), moderate fiber levels (3–4% crude fiber) combined with enzyme supplementation support gastrointestinal development while sustaining optimal growth performance. By the finisher phase (25+ days), strategic fiber inclusion at 4–5% helps reduce feed costs while promoting gut health and desirable meat quality parameters.

Advantages and Limitations
Insoluble fiber supplementation improves gut health by stimulating gizzard development, promoting intestinal morphology, and enhancing growth of beneficial microflora without adverse increases in digesta viscosity. It also provides measurable behavioural and welfare benefits—reducing cannibalism and supporting satiety in laying hens. By improving excreta consistency, insoluble fiber minimizes moisture, ammonia emissions, and infection risks. From a sustainability standpoint, utilizing agricultural by-products such as hulls and bran helps recycle waste and reduce environmental impact.

However, excessive use of insoluble fiber can dilute nutrient density, potentially impairing bird performance and necessitating careful dietary balancing. Variability in natural fiber sources—regarding composition, particle size, and quality—poses challenges for consistent feed formulation unless standardized products are used. Traditional sources such as wheat bran carry substantial mycotoxin risks; coarse materials can also complicate feed processing and flow. Moreover, insoluble fiber is poorly fermented, not contributing to beneficial short-chain fatty acid production observed with soluble fiber inclusion.

Market Trends and Future Perspectives
The global high-fiber feed market is projected to expand at a CAGR of approximately 6% through 2033, driven by rising consumer demand for welfare-centric, antibiotic-free poultry production. Current trends emphasize: Adoption of precision nutrition and stage-specific fiber blends. Expanded use of purified, standardized lignocellulose as a safe alternative to brans. Integration of fiber with probiotics and enzymes for optimized synergistic effects. Alignment with circular economy goals by valorizing crop by-products for feed.

Conclusion
Insoluble fiber, though metabolically inert, plays a fundamental physiological and metabolic role in poultry nutrition. Its inclusion enhances digestive efficiency, improves nutrient utilization, promotes gut health, optimizes excretion, and contributes to sustainable and welfare-friendly production systems. With ongoing innovations in fiber processing and precision feeding strategies, insoluble fiber presents substantial opportunities to improve poultry performance and farm sustainability. Proper management of inclusion rates and strict quality control remain critical for maximizing its benefits.

Nutritional strategies to support the production of high quality, low cost and safe animal products are a must nowadays. The relationships between health, nutrition, welfare, and environment need to be considered. In poultry production, increasing feed costs are imposing pressure on the profitability of the farmer, so nutritionists seek to reduce feed costs whilst maintaining animal performance and gut health. Several strategies, with tangible tools to support this, are discussed in this article.

CONTROLLING COCCIDIOSIS

Coccidiosis, caused by protozoan parasites of the genus Eimeria, is one of the most widespread and difficult to manage poultry diseases, resulting in considerable economic losses in the broiler industry. Insufficient or inadequate control of coccidiosis will result in gut health damage and provide a pathway for other pathogens to proliferate.

For instance, suboptimal coccidiosis control combined with a high amount of undigested protein will create an ideal situation for the proliferation of Clostridia spp. Birds suffering from clinical coccidiosis will show typical signs like diarrhoea, bloody droppings, increased mortality, decreased feed intake and impaired performance.

Inadequate control of coccidiosis leads to impaired growth and feed conversion ratio, without the presence of evident clinical signs. This is subclinical coccidiosis.

Intensive methods of production of poultry favour the reproduction of Eimeria. Consequently, coccidiosis is a continuing problem requiring constant attention and, in the case of broilers, a need for continuous supplementation with anticoccidial drugs or coccidiosis vaccines, in addition to in-feed anticoccidials. Coccidiosis control combined with a good monitoring programme will be the base of any gut health management programme.

IMPROVING FEED DIGESTIBILITY

Improving digestibility of the feed can be achieved by selecting highly digestible feedstuffs. However, this will increase the feed price. The improvement of the digestibility of feed by using enzymes able to degrade Non-Starch Polysaccharides (the so-called NSPases) will not only lead to lowering the feed cost at formulation, but also exert a positive effect on the bird’s gut health.

The NSPases contain xylanase or xylanase-based enzymatic complexes, and their mode of action includes the hydrolysis of soluble arabinoxylans, which minimises intestinal viscosity, preventing the overgrowth of microflora and thereby reduces gut health disorders.

Together with the efficient reduction in viscosity, NSPases will also hydrolyse insoluble arabinoxylans. This action will unlock nutrients (mainly starch and proteins) which are trapped in the cell walls of the vegetable feed ingredients (the so called ‘cage effect’ of insoluble fibres).

Using the correct NSPase leads to improved digestibility of starch and protein. The latter is of particular importance as high levels of undigested protein in the (last) part of the intestine is a breeding ground for protein-loving pathogens like Clostridium spp, causing necrotic enteritis.

The breakdown of arabinoxylans by NSPase also yields arabino- oligosaccharides (AXOS) which are known to be fermented by the microflora in the lower part of the intestine to butyrate, which is a major energy source for villi regeneration allowing good gut health status.

Phytases have been shown not only to break down phytate to release phosphorus, but by doing so, to also destroy the anti-nutritional factor phytate.

This not only leads to a reduction of endogenous protein losses, but also liberates protein and amino acids which are complexed by phytate, enhancing their digestibility.

SUPPORTING THE MICROBIOTA

The relationship between a healthy gut and the animal’s microbiota is undeniable. As part of the holistic approach, the inclusion of probiotics in the nutritional programme offers a way of supporting gut health from a microbial perspective.

The mode of action of probiotics is usually multifactorial, including (but not limited to) the production of beneficial metabolites or the direct competition with unwanted bacteria. As a result, probiotics often help to balance the present microbiota and improve its robustness, supporting general gut health in the process. Probiotics can be incorporated into the feed or drinking water, depending on the strain and formulation used.

Although there are many commercial options available, the preferred product of choice should be based on a single unique strain, capable of forming spores and with a proven and researched mode of action. Such probiotics increase the ease of use, whilst ensuring product efficacy.

Good examples are B-Act®, containing viable spores of Bacillus licheniformis, based on Clostridium butyricum. Probiotics allow producers to support their animals’ gut health efficiently, setting them up for a successful production period from start to finish.

CONCLUSION

Gut health management is of paramount importance to the profitability of poultry farming. The strategy behind managing optimal gut health should contain a combination of the most important control tools on the market available today: an adequate and well thought-through coccidiosis control programme, combined with an NSP enzyme and a phytase, and topped off by a well-functioning probiotic.

Trace minerals such as zinc, copper, and manganese are fundamental to poultry health, acting as cofactors in vital biochemical pathways: skeletal development, immune defenses, antioxidative systems, enzyme functions, feathering, and reproductive performance. Yet, the typical composition of feed ingredients often falls short of modern poultry standards. That’s why precision mineral nutrition—providing the right mineral at the right time and in the right form—is essential to support optimal broiler growth, eggshell integrity in layers, and fertility in breeders.

While inorganic sources like sulfates and oxides have been staples for decades, they suffer from low bioavailability and reactiveness. These soluble compounds can prematurely release minerals, which then form insoluble complexes with phytate or binding agents in the gut, diminishing absorption and even degrading vitamins or enzymes in the premix. This not only reduces feed efficiency but also increases mineral excretion, raising environmental concerns. Organic (chelate) minerals improved this situation, but often at a premium cost and with variable potency. Enter the next generation: hydroxy trace minerals. Hydroxy trace minerals, like copper, zinc, and manganese hydroxychloride, represent the latest leap in mineral nutrition. Their crystalline, covalent structure is non-hygroscopic and non-reactive in feed and the upper gut. This structure allows slow, controlled release of minerals at the ideal intestinal absorption site, significantly improving bioavailability. They resist premature dissolution, ensuring minerals are released more slowly and absorbed where it matters most.

Research across poultry sectors consistently shows that hydroxy trace minerals outperform inorganic sources. Broilers fed hydroxy copper and zinc achieved 7–8% heavier carcasses and a noticeable boost in breast meat yield. In independent trials, hydroxy-supplemented flocks maintained or improved feed conversion ratios while using lower inclusion levels than sulfate-based diets . Moreover, in antibiotic-free or necrotic enteritis challenge models, hydroxy minerals reduced pathogen load and mortality, performing on par with ionophores. Layers also benefit: eggshell quality improves, feed remains stable longer (less oxidation), and FCR gains are consistent when inorganic Cu, Zn, Mn are replaced with hydroxy versions. Breeder flocks, too, see enhanced fertility and hatchability under precision hydroxy mineral regimes.
Beyond performance, hydroxy trace minerals contribute to gut integrity and immune defense. Broilers on hydroxy mineral diets exhibited reduced cecal enterobacteria and maintained tight junction integrity, translating into healthier birds and better carcass quality.

Another Trouw Nutrition joint trial with the University of New England demonstrated improved bone integrity (tibia breaking strength) and breast meat zinc content in broilers fed 100 ppm IntelliBond Zn, with gut integrity maintained. In antibiotic-free commercial conditions, hydroxy copper-chloride combined with organic acids matched or exceeded the performance gains of feed antibiotics while improving egg weight, mass, and feed efficiency in layer hens. These findings highlight the ability of IntelliBonds to deliver consistent productivity gains across broilers, layers, and breeders—even under stress or antibiotic-free regimes. Trouw Nutrition India has been pioneering mineral-precision feeding. “Trouw Talks” events in Karnal and Hyderabad, unveiled IntelliBond’s OptiSize® technology—highlighting uniform, stable crystals that protect premix integrity and animal performance. Trouw Nutrition’s new premix plant near Hyderabad supports local production of trace minerals, vitamins, and specialized premixes—readying India for advanced feed solutions. This investment and local research infrastructure underline Trouw Nutrition’s strong commitment to validating hydroxy mineral efficacy under Indian production conditions.

Why IntelliBond® Stands Out

Trouw Nutrition’s OptiSize® technology guarantees uniform particle size and non-hygroscopic behavior. Its low reactivity protects feed integrity, while rigorous traceability—from raw material origins to lot distribution—ensures feed safety and compliance.

Modern poultry production demands precision: the right trace mineral, in the right form, at the right level. Hydroxy trace minerals—especially IntelliBond®—deliver on that promise. Scientific evidence and Trouw Nutrition’s local investments prove that these superior minerals enhance productivity, welfare, and sustainability in broilers, layers, and breeders. By choosing IntelliBond®, nutritionists and producers gain a trusted, research-backed solution that fosters better performance, protects investments, and advances poultry industry goals in India and beyond.

Poultry excreta comprises undigested feed protein and uric acid, which microbial enzymes convert to ammonia (NH3). Several litter characteristics, including pH, temperature, oxygen, moisture concentrations, and substrate availability, influence this conversion. The recommended limit for ammonia in a chicken shed is less than 10 ppm, however, up to 25 ppm is not detrimental. Ideally, the relative humidity should range between 50 and 70%. The rainy season, defective foggers, insufficient ventilation, water leaks, and other factors all contribute to increased humidity inside the shed.

Ammonia levels and humidity in poultry houses are interconnected. High relative humidity can exacerbate the adverse effects of high blood ammonia levels in poultry. In humid environments, more NH3 may be dissolved in the air droplets and inhaled into the blood during respiration by birds, consequently increasing the blood ammonia content. When ammonia gas is exposed to moisture, it reacts and forms a corrosive solution called ammonium which causes harm to birds. Additionally, high humidity can hinder the evaporation of moisture from the litter, causing it to retain more ammonia.

Deleterious Effects on Poultry:
1. Respiratory Issues: High levels of ammonia in the poultry house air can cause respiratory problems for the birds. Ammonia gas affects the trachea’s mucosal surface, causing paralysis of cilia, sometimes deciliation of epithelial cells, and causes necrosis of the mucosal epithelium.
2. Foot Lesions: The constant exposure of poultry to ammonia can cause severe foot lesions by causing chemical burns on the foot pads of birds, leading to painful and debilitating footpad dermatitis.
3. Eye Lesions: High concentrations of atmospheric ammonia for a prolonged duration causes irritation, conjunctivitis, and damage to the cornea of the eyes. Swelling and reddening of the eyelids, irritation, reddening of the conjunctiva and nictitating membrane, and partial or complete closure of the eyes are common clinical signs.
4. Reduced performance.

How to prevent it:
Along with farming management like dietary management, stocking density, proper ventilation, house temperature, litter management, etc., other supplements like Phytogenic Feed Additives can be supplemented in a poultry diet. A phytogenic feed additive increases the digestibility of nutrients within the gastrointestinal tract and reduces the gut inflammation caused by stressors.

Thereby may considerably increase the gut integrity of the birds. Phytogenic feed additives also alter gut microflora, minimizing the adverse effect of harmful bacteria on the gut. Less undigested and unabsorbed nutrients will be excreted through faeces from a healthy gut, which means less nitrogen excretion.

STODI, a Standardized Botanical Powder, is crafted with scientifically selected herbs improving the efficiency of feed utilization and overall performance of the birds. In various studies, it has been found that STODI supplementation has significantly reduced litter nitrogen (g/100g of litter) as compared to group without supplementation. STODI maintains the gut integrity and peristaltic movement of the gut which increases time for the protein and other nutrient utilization by the birds. This increased protein utilization leads to reduced excretion reduced excretion of nitrogen which in turn decreases the production of ammonia level in litter. Along with this STODI has shown to improve the gut microbiota level and gut immunity of the birds.

In conclusion, the combined impact of ammonia and humidity in the world of poultry farming underscores the critical importance of maintaining a balanced and controlled environment for the well-being and productivity of the birds. High levels of ammonia in poultry houses can lead to a range of deleterious effects. STODI, a polyherbal formulation has shown to reduce the ammonia level in litter with improved nutrient utilization and gut microbiota balance.

Introduction
Imbalances in the intestinal microbiota are linked to the development of various diseases. As a result, there has been growing interest in using prebiotics, probiotics, and postbiotics to modulate the gut microbiome. Postbiotics refer to substances released or produced through the metabolic activity of microorganisms that exert beneficial effects on the host, either directly or indirectly. Since postbiotics do not contain live microorganisms, the risks typically associated with their consumption are significantly reduced.

In this review, we critically examine current literature on postbiotics, focusing on their mechanisms of action and potential applications in performance trials. We highlight their distinct benefits compared to live probiotics, with the goal of maximizing the effectiveness of postbiotics in target animals. The review explores their key components and advantages related to diet and gut health, emphasizing their role in supporting animal production—particularly in poultry. Relevant studies are referenced to illustrate the immunomodulatory, antimicrobial, anti-inflammatory, and antioxidant properties of postbiotics, as well as their overall impact on productivity and health in animal systems.

How to distinguish postbiotics and their benefits compared to live probiotics?

Postbiotics are metabolic by-products produced by bacteria (exogenous postbiotics). They include non-viable bacterial components and substances such as short-chain fatty acids (SCFAs), peptides, bacteriocins, proteins, and amino acids, all of which can confer health benefits to the host. Unlike probiotics, postbiotics are more stable during feed processing and under various environmental conditions. This enhanced stability, along with their enriched nutrient profile, makes postbiotics a promising alternative to probiotics in animal feed applications.

The use of postbiotics as a tool for improving the health of livestock and poultry shows great promise, owing to their numerous benefits and several advantages over probiotics and prebiotics. As metabolic byproducts or components derived from probiotic bacteria, postbiotics are less sensitive to environmental factors such as temperature, pH, and processing methods (Hossain et al., 2021). This enhanced stability allows them to retain their functional and beneficial properties over time, making them well-suited for diverse applications in animal health and nutrition (Thorakkattu et al., 2022).

Furthermore, we provided the information of postbiotics that can offer more advantages than live probiotics; for instance, (Rafique et al., 2023),

(a) Live probiotics may struggle to adhere to the gut mucosa due to the presence of a mucous layer that limits direct contact between bacteria and the epithelial surface. In contrast, postbiotics can more easily penetrate this mucous layer.
(b) Postbiotics pose no risk of infection from bacterial translocation from the intestinal lumen into the bloodstream, which is particularly important for immunocompromised or susceptible individuals. Additionally, they do not carry the risk of acquiring or transferring antibiotic resistance genes.
(c) Postbiotics offer practical advantages—they are easier to dose, transport, standardize, and store. Moreover, they have significant potential to support intestinal barrier function and may serve as an effective alternative to probiotics (Liu et al., 2023).

The benefits of postbiotics for gut health.
Postbiotics can inhibit the growth of pathogens and strengthen gut barrier function through the action of short-chain fatty acids (SCFAs). For instance, butyrate serves as an energy source for colon epithelial cells and the intestinal mucosa, thereby supporting gut integrity and reducing intestinal permeability.
In addition to enhancing gut barrier function, butyrate plays a role in immunomodulation and exhibits anti-inflammatory effects while helping to improve growth performance, as illustrated in Figure 1.

Figure 1: Functions of postbiotics

Butyric acid has demonstrated in vitro antimicrobial activity against both Gram-positive bacteria (e.g., Enterococcus faecalis, Clostridium perfringens, Streptococcus pneumoniae, Streptococcus suis) and Gram-negative bacteria (e.g., Escherichia coli, Salmonella enterica Typhimurium, Campylobacter jejuni) (Kovenda et al., 2019).

The mode of action of sodium butyrate involves its conversion to butyric acid, which can penetrate bacterial cell walls primarily through diffusion. Once inside the cell, butyrate induces cytoplasmic toxicity by lowering the intracellular pH. This acidification disrupts key metabolic processes, depletes energy reserves, and leads to the excretion of protons (H⁺), which further diffuse into the bacterial cell and contribute to toxicity. The increased proton concentration interferes with ATP synthesis by impairing the bacterial cell’s ability to maintain proton gradients essential for energy production and metabolism. Ultimately, the drop in pH and metabolic disruption result in bacterial cell death (Ahsan et al.,2016).

Maximize the effectiveness of postbiotics in target animals.
Based on researches, postbiotic can be able to target gut-brain axis influence on serotonin to improve growth performance (Sofie et al., 2021; Ishii et al.,2019), gut health and nutrient digestion (Ahmed et al., 2014; Kumar et al., 2014), antimicrobial (Mantziari et al., 2020; Fong et al., 2020), anti-inflammation and Immune-microflora balance (Torino et al., 2015; Miyazawa et al., 2015; Maghsood et al., 2018;) including postbiotic/probiotic as an alternative ATB/ZnO (Ali et al., 2023).

FermNutral® derived from the biological fermentation of the probiotic strain Clostridium butyricum, the main components of the product include amino acids, minerals, and beneficial metabolites classified as postbiotics. Rafique et al. (2023), writing in the Journal of Agriculture & Food Research, reviewed the principal classes of postbiotics with health-promoting effects:

1. Short-chain fatty acids (SCFAs) –
Butyrate supports gut integrity, reduces intestinal permeability, modulates immunity, exerts anti-inflammatory actions, and suppresses pathogens. In broilers, butyrate also raises apparent total‑tract crude‑fat digestibility and apparent metabolizable energy (AME), enhancing overall digestion and nutrient absorption.
2. Antimicrobial peptides (bacteriocins) – These peptides display activity against common pathogens, including Salmonella spp., Staphylococcus aureus, Yersinia enterocolitica, and Escherichia coli.
3. Quorum‑sensing (QS) interference – Certain postbiotics inhibit pathogen biofilm formation by disrupting QS signaling, thereby curbing colonization and persistence.
4. Polysaccharides (e.g., teichoic acids) – Contribute anti‑ inflammatory and antimicrobial effects, further supporting host health.
5. B‑complex vitamins, proteins, and amino acids – Provide additional nutritional and functional benefits that complement the antimicrobial and immunomodulatory actions of other postbiotic fractions.

Postbiotic product in poultry trials
FermNutral (FN)® is a postbiotic product consisting of non-living microorganisms (inactivated bacteria) or their components that provide health benefits to the host. It also includes byproducts of probiotic activity in the gut, such as fermentation metabolites.

The main ingredient is calcium butyrate, which makes up 50% of the product. Other components include short-chain fatty acids (butyric acid, acetic acid, propionic acid), 18 amino acids, vitamins (B1, B2, B5, B6, B12, folic acid, E, and K), and minerals (Ca, Fe, Zn, Na, Mg, P, Mn, Cr).

Based on our trial data and correlated research publications, we can confidently say that FN improves productive performance and reduces feed costs, which contributes to higher profits and effective solutions in animal production.

Typically, we focus on both performance and economic returns in animal production, especially for pigs, poultry, and aquatic species. Through extensive research conducted by CP BIO, we have found that using FN in aquatic animals such as Tilapia, Ruby fish, Penaeus vannamei, and Micropterus salmoides significantly enhances growth performance, feed efficiency, survival rates, and overall economic returns, as shown in Table 1.

Conclusions
FermNutral (FN) is a biological fermentation product derived from the probiotic strain Clostridium butyricum. It primarily contains short-chain fatty acids (SCFAs), especially butyrate, along with amino acids, minerals, and beneficial metabolites acting as postbiotics. Essentially, FN functions through the diet-gut-microbe axis to provide effective animal health solutions. Butyrate mainly supplies energy to the epithelial cells of the colon, improving digestion and nutrient absorption while controlling pathogens, maintaining immune balance, and reducing inflammation. Therefore, the multi-modal actions of FN help support gut function, enhancing animal performance and profitability.
