In the early stages of life, young animals face a hidden nutritional challenge that often goes unnoticed, their ability to digest fats is naturally limited. This is not a flaw, but a biological reality tied to how their digestive systems develop.

Fat, or lipid, is one of the most energy-dense components in animal feed. It plays a critical role in growth, immunity, and overall performance. However, for fat to deliver its full value, it must first be properly digested and absorbed. In young animals, this process is not yet fully efficient.

The primary reason lies in the underdevelopment of key digestive components. Lipase, the enzyme responsible for breaking down fats, is produced at low levels in young animals. At the same time, bile production, which is essential for emulsifying fats and making them easier to digest, is also limited. Without sufficient bile salts and lipase, fats pass through the digestive system without being fully utilized.

This limitation is especially evident in poultry. In young broilers, the digestive system requires time to mature, typically around 10 to 14 days. During this period, fat digestibility is significantly reduced. As a general guideline, birds under 10 days of age can experience up to a 10 percent reduction depending on fat source and formulation in fat energy utilization.

Figure 14: Influence of broiler age on lipid digestibility.

Scientific observations further highlight this gap. The ability of broilers to absorb corn oil improves dramatically from 84 percent in the first week to 95 percent in the second week of life. Similarly, the absorption of more complex fats such as tallow increases from 40 percent to 79 percent over the same period. This shows not only the initial limitation, but also how quickly the system develops once maturity begins.

The challenge is even more pronounced when diets contain saturated fats or high levels of free fatty acids. These types of fats are inherently more difficult to digest, placing additional strain on an already immature digestive system.

A similar pattern is observed in piglets. During the first week after birth or immediately after weaning, pancreatic and intestinal lipase activity remains low. This further reduces the animal’s ability to efficiently utilize dietary fats, limiting the energy they can extract from feed during a critical growth phase.

The consequence of this inefficiency is both biological and economic. When fat digestibility is low, animals require higher levels of dietary energy to meet their needs. This often leads to increased inclusion of energy-rich ingredients, driving up feed costs without guaranteeing optimal absorption.

This is where nutritional strategies become essential. Supporting fat digestion during this early stage can significantly improve energy utilization and overall performance. One such approach is the use of lysolecithin, an emulsifier that enhances the breakdown and absorption of fats even when the animal’s natural systems are not fully developed.

By improving fat digestibility, especially in young animals, producers can bridge the gap between nutritional potential and actual performance. The result is more efficient feed use, better growth outcomes, and a stronger foundation for long term animal health.

In the bigger picture, optimizing early nutrition does more than improve animal performance. It supports a more sustainable and cost-effective production system, ensuring that every unit of feed delivers real value, from farm to table.

At the end of the day, when a family gathers around the table, the meal placed in the center often feels simple. A dish of meat, shared among loved ones, represents comfort, provision, and care. Yet behind that moment is a complex journey shaped by science, responsibility, and decisions made long before the food ever reaches the plate.

Today, families everywhere are feeling the pressure of rising food costs. Meat, once a staple, is becoming something people think twice about. The question is no longer just what to cook, but how to balance nutrition with affordability. What many do not see is that the answer to this challenge does not begin at the supermarket. It begins at the farm, at the level of animal nutrition.

When animals are not fed with precision and care, inefficiencies begin to build. Feed is one of the largest costs in livestock production, often accounting for up to 70 percent of total expenses. If nutrients are not properly digested and absorbed, a significant portion of that feed is wasted. This leads to slower growth, weaker animals, and higher susceptibility to disease. Farmers are then forced to spend more on additional feed, treatments, and time, all of which increase the cost of producing meat.

The science of feed efficiency is where transformation begins. Products like lysolecithin play a critical role in improving fat digestion, even in diets that are low in added fats. In the animal’s digestive system, fats are naturally difficult to break down because they are not water soluble. Lysolecithin acts as an emulsifier, increasing the surface area of fat droplets and allowing digestive enzymes such as lipase to work more effectively. This process enhances the formation of micelles, which are essential for transporting fatty acids across the intestinal wall for absorption.

The result is not just better fat utilization, but improved absorption of all fat soluble nutrients, including vitamins A, D, E, and K. Studies have shown that improving fat digestibility can increase overall energy utilization, which directly contributes to better growth rates and improved feed conversion ratios. Even a small improvement in feed conversion, for example from 1.7 to 1.6, can translate into substantial cost savings when applied across large scale production.

At the same time, trace minerals such as zinc proteinate are critical in supporting the animal’s immune system. Zinc is essential for the development and function of immune cells, including phagocytes and lymphocytes, which are involved in recognizing and eliminating harmful pathogens. It also contributes to the protection of cells from oxidative damage by supporting zinc‑dependent enzyme systems and cellular defense mechanisms, helping to limit oxidative stress during periods of inflammation or immune challenge. In addition, zinc supports enzyme activity, epithelial and barrier integrity, and immune signaling pathways, helping to maintain an immune response that is effective while avoiding excessive or chronic inflammation.

When these nutrients are delivered in highly bioavailable forms, animals are better equipped to resist infections naturally. This reduces the need for antibiotics, lowers mortality rates, and ensures more consistent production outcomes. Healthier animals grow more efficiently, convert feed more effectively, and produce higher quality meat with better composition and nutritional value.

All of these improvements create a ripple effect throughout the production chain. When feed is used more efficiently, farmers spend less on inputs. When animals are healthier, fewer resources are lost to disease. When production becomes more predictable, supply stabilizes. These efficiencies reduce the cost per kilogram of meat, making it more accessible without compromising quality.

This is where science meets real life. The innovations applied at the level of animal nutrition directly influence what families experience at the table. Better nutrient absorption leads to stronger animals. Stronger animals lead to more efficient production. More efficient production helps stabilize prices and ensures that nutritious meat remains within reach for more households.

At GN Good Nutrition, this connection drives every formulation. The goal is not just to enhance performance on the farm, but to support a system that benefits both producers and consumers. By focusing on nutrient efficiency, gut health, and immune support, the impact extends far beyond the farm.

So when a family sits down to share a meal, that piece of meat represents more than nourishment. It reflects a chain of scientific precision, responsible farming, and thoughtful innovation. It represents a system working quietly in the background to ensure that food remains both nutritious and attainable.

In a time when every household is watching their spending, this matters deeply. Because true nutrition is not just about feeding animals. It is about building a system that sustains farmers, supports economies, and allows families to gather around the table with confidence, knowing they can provide both quality and care.

In animal nutrition, lysolecithin is often associated with improving fat digestion, especially in high oil diets. But a common question remains: does it still deliver value when fat inclusion is low or when no additional oil is added?

Scientific evidence suggests that the answer is yes, and the reason lies in how lysolecithin works at a deeper physiological level.

Beyond Added Fats: Working with What is Already There

Even in diets without added oils, common feed ingredients such as corn, soybean meal, and DDGS naturally contain lipids. These intrinsic fats still require proper emulsification and digestion within the gastrointestinal tract.

Lysolecithin enhances the emulsification of these naturally occurring lipids, improving their breakdown and absorption. This means that its function is not limited to added fat, but extends to maximizing the utilization of all available lipid sources in the diet.

Enhancing Nutrient Absorption and Gut Efficiency

Lysolecithin plays a key role in the formation of micelles, which are essential for transporting lipids and fat soluble nutrients across the intestinal wall. Improved micelle formation leads to better absorption not only of fats, but also of vitamins such as A, D, E, and K.

Beyond lipid digestion, research has shown that emulsifiers like lysolecithin can improve overall nutrient digestibility. This includes energy and dry matter, indicating a broader impact on feed efficiency.

Additionally, lysolecithin has been linked to improvements in intestinal morphology, such as increased villus height. A healthier intestinal structure allows for greater surface area, which enhances nutrient absorption across the board.

Supporting Performance in Low Energy Diets

In low fat or reduced energy diets, animals often face limitations in available energy. Lysolecithin helps address this by improving the efficiency with which nutrients are utilized.

Studies have demonstrated that even in low energy formulations, emulsifier supplementation can lead to improved growth performance and feed conversion ratios. While the magnitude of improvement may be smaller compared to high fat diets, the benefits remain consistent and economically relevant.

A Functional Tool, Not Just an Add On

The role of lysolecithin should not be viewed solely as a fat emulsifier for high oil diets. Instead, it functions as a tool for improving nutrient utilization, gut efficiency, and overall performance.

Conclusion

Lysolecithin remains effective across a range of dietary conditions. It improves fat digestibility regardless of whether the fat is added or naturally present, enhances overall nutrient absorption, and supports animal performance even in low fat or low energy diets.

For nutritionists and feed formulators, this means that lysolecithin is not just a conditional additive, but a versatile component in optimizing feed efficiency and animal health.

Inflammation is the body’s early warning system, turning on when tissues are injured or when pathogens invade. In dairy cows this response is common in cases of mastitis, where udder tissue becomes inflamed, painful and less productive. Managing the intensity and duration of inflammation may support recovery and help maintain milk quality.

A growing body of scientific evidence suggests that zinc plays an important role in regulating inflammation and immune function. Research published in peer‑reviewed nutrition journals describes how this micronutrient influences immune cells and inflammatory pathways in mammals. While much of this work has been done in humans and laboratory animals, many of the underlying immune mechanisms are conserved across species, and are therefore considered relevant to dairy cattle as well.

Zinc as a Modulator of Immune Signals  

Zinc is essential for many cellular functions. It helps cells divide, supports the structure of proteins, and acts as a cofactor in hundreds of enzymes. One of its key roles is in immune regulation. Zinc can influence the activity of Nuclear Factor Kappa B (NF‑κB), a central transcription factor that drives the expression of many pro‑inflammatory molecules. By modulating NF‑κB and related signalling pathways, adequate zinc status may help prevent excessive inflammatory signalling rather than simply shutting inflammation down.

When zinc levels are within an optimal range, immune cells are more likely to function efficiently, and the signals that trigger inflammation may remain better balanced. In contrast, insufficient zinc can impair normal immune responses and has been associated in various species with exaggerated or poorly controlled inflammation, which may contribute to tissue damage over time.

What Science Says About Zinc and Inflammation  

Reviews of zinc and immunity report that zinc deficiency weakens host defence and increases susceptibility to infections. In zinc‑deficient systems, inflammatory cytokines are often produced in higher amounts, and the resolution phase of inflammation can be impaired. These changes may slow recovery from infections and increase the risk of collateral tissue damage during the inflammatory response.

Zinc is also involved in both innate and adaptive immunity. Innate immunity provides the first rapid response to invading pathogens, while adaptive immunity helps the body develop more specific and longer‑term protection. By influencing multiple immune cell types, zinc may help the body respond effectively to pathogens while also reducing the risk of an over‑active, damaging inflammatory response.

Relevance to Udder Health and Mastitis  

In dairy cows, mastitis involves bacterial invasion of the mammary gland, triggering inflammation and swelling of udder tissue. Redness, heat, pain and changes in milk are familiar signs of this process. Adequate zinc nutrition may support more balanced immune signalling in these situations, potentially helping the cow mount an effective defence while limiting unnecessary tissue damage.

Producers recognise that uncontrolled or prolonged inflammation can reduce milk yield, disrupt milking routines and increase the need for treatment. As part of a complete nutritional program, ensuring that cows receive appropriate levels and forms of zinc may help support normal immune function and promote timely resolution of inflammation. Evidence from other mammals, together with nutrition and field studies in cattle, suggests that optimal zinc status can support immune cell activity and may help reduce the likelihood of excessive inflammatory mediator production, which in turn could contribute to more favourable clinical outcomes.

It is important to note, however, that mastitis is multifactorial. Pathogen load, milking hygiene, housing conditions, energy balance, and other vitamins and trace minerals (such as selenium, vitamin E and copper) all interact with zinc status to influence udder health. Zinc nutrition should therefore be viewed as one component of a broader mastitis control strategy, rather than a stand‑alone solution.

Practical Takeaways  

Zinc is more than just a trace element in the ration. It contributes to immune system balance, cell membrane integrity and modulation of inflammatory pathways. For dairy cows, this may translate into more effective recruitment of immune defences when challenged by mastitis‑causing pathogens and a reduced risk of unnecessarily prolonged inflammation that can harm udder tissue.

In practice, formulating diets to provide adequate and bioavailable zinc, in balance with other minerals and overall energy and protein supply, aligns with modern herd health management. Working with a nutritionist or veterinarian to evaluate zinc sources and inclusion levels can help ensure that nutritional support for immune function complements good management, hygiene and milking practices. Taken together, these measures may help protect production and support the lifetime udder health and productivity of the herd.

When discussing fat digestion and absorption in animal nutrition, micelles play a silent yet critical role. Understanding how micelles work helps nutritionists and feed formulators choose the right emulsifiers like lysolecithin to improve nutrient uptake, feed efficiency, and animal performance.

The Science Behind Micelles

A micelle is an aggregate of surfactant or amphipathic lipid molecules dispersed in a liquid, forming a colloidal suspension, a stable mixture with insoluble particles permanently dispersed in another substance.

In a typical oil-in-water micelle, the hydrophilic (“water-loving”) head groups of the molecules face the surrounding water, while the hydrophobic (“water-repelling”) tails cluster at the center. This arrangement allows oils and fats to remain evenly dispersed in an aqueous environment.

In contrast, inverse micelles form in non-polar media, with hydrophilic heads inside and hydrophobic tails extending outward. The structure a micelle takes; spherical, lamellar, cubic, or hexagonal, depends on the properties of the emulsifier, such as its hydrophilic-lipophilic balance (HLB) and molecular geometry.

Micelles in Fat Digestion and Absorption

Micelles are vital to lipid digestion, as they serve as the transport carriers for fat digestion products like monoglycerides, free fatty acids, and fat-soluble vitamins. Being water soluble, micelles enable these otherwise insoluble components to move efficiently toward the intestinal wall for absorption.

Here’s how the process typically works:

1. Emulsification – Bile salts or added emulsifiers (e.g., lysolecithin) break dietary fats into tiny droplets, increasing surface area for enzyme action.

2. Micelle Formation – The products of fat digestion combine with bile salts and emulsifiers to form mixed micelles.

3. Absorption – Micelles travel to the intestinal membrane, where they disintegrate, releasing their contents for absorption by passive diffusion.

4. Recycling – Bile salts are reabsorbed and reused in continuous emulsification cycles, a process known as bile recycling.

Micelle Efficiency and Species Differences

Not all species form micelles equally. For example, shrimp lack a bile secretion system, which limits their ability to form stable micelles. This leads to:

• Less efficient fat emulsification

• Lower lipid absorption

• Reduced hepatopancreas function and compromised growth performance

In such species, supplementing feeds with efficient emulsifiers like lysolecithin can compensate for this natural limitation, enhancing nutrient absorption and gut health.

Lecithin and lysolecithin are widely used feed ingredients in animal nutrition, especially in diets where fat digestion and energy utilization are critical. While they are closely related, their functionality in the digestive system is not the same.

Understanding the difference between lecithin and lysolecithin helps farmers, nutritionists, and feed formulators choose the right emulsifier to improve fat digestibility, feed efficiency, and animal performance.

What is lecithin?

Lecithin is a naturally occurring phospholipid found in animal and plant tissues. It is commonly extracted from sources such as soybeans, sunflower seeds, or eggs. Structurally, lecithin contains a glycerol backbone with two fatty acid tails and a phosphate based head group.

Because it has both water loving and fat loving components, lecithin acts as an emulsifier. In animal feed, lecithin helps fats mix with water so digestive enzymes can access them more easily.

However, lecithin is relatively fat-loving due to its two fatty acid tails, which limits its effectiveness in the aqueous environment of the gastrointestinal tract.

What is lysolecithin?

Lysolecithin is a modified form of lecithin. The term “lyso” comes from the word lysis, meaning splitting. Through enzymatic processing, typically using phospholipase enzymes, one fatty acid tail is removed from the lecithin molecule.

This structural change creates a smaller, more hydrophilic molecule. Lysolecithin is also known as hydrolyzed lecithin or lysophosphatidylcholine and is classified as E 322.

Because lysolecithin contains only one fatty acid tail, it behaves very differently during digestion.

Figure 1: Enzymatic conversion of lecithin to lysolecithin.

Lecithin vs lysolecithin, structural differences

The key difference between lecithin and lysolecithin lies in their fatty acid composition.

Lecithin

• Two fatty acid tails
• More lipophilic
• Larger molecular structure

Lysolecithin

• One fatty acid tail
• More hydrophilic
• Smaller molecular structure

This difference directly affects how each compound performs as an emulsifier in the digestive tract. Lecithins may also be modified by a process called fractionation. During this process, lecithin is mixed with an alcohol, usually ethanol. Some phospholipids, such as phosphatidylcholine, have good solubility in ethanol, whereas most other phospholipids do not dissolve well in ethanol. The ethanol is separated from the lecithin sludge, after which the ethanol is removed by evaporation to obtain a phosphatidylcholine-enriched lecithin fraction.

Compared to lecithin, because one molecule in the hydrophobic tail is removed in lysolecithin, the resulting lysophospholipids are smaller and result in more hydrophilic molecules than phospholipids. This improves their emulsifying capacity in oil-in-water environments (Figure 2), as found in the aqueous environment of the gastrointestinal tract, thus improving the process of digestion of dietary fats and oils (Figure 3), particularly saturated fats.

Figure 2: Vitalsorb Pure disperses faster than non-hydrolyzed lecithin.

Both products mixed for 15 seconds

Figure 3: Comparing micelle formation for non-hydrolyzed lecithin and lysolecithin.

Why lysolecithin works better in digestion

The gastrointestinal tract is a water based environment. For fats and oils to be absorbed, they must first be broken into very small droplets called micelles. These micelles transport lipids through the gut and deliver them to the intestinal wall for absorption.

Lysolecithin forms smaller and more stable micelles than lecithin. Smaller micelles move more efficiently through the unstirred water layer that lines the intestine, improving fat absorption.

Research has shown that micelles containing lysolecithin diffuse faster and improve lipid uptake compared to micelles formed with lecithin. In some studies, intestinal cholesterol uptake was many times higher when lysolecithin was present.

Lysolecithin also has a higher hydrophilic lipophilic balance and a lower critical micelle concentration than lecithin. This means it can emulsify fats more effectively at lower inclusion levels.

Effects on fat digestibility and feed energy

Multiple studies have demonstrated that lysolecithin improves fat digestibility and dietary energy utilization more effectively than lecithin. This is especially important in young animals, such as broilers, whose digestive systems are not fully developed.

In feeding trials, lysolecithin significantly improved energy values and nutrient digestibility, while lecithin showed limited or no improvement under the same conditions.

Lysolecithin is particularly effective in diets containing saturated fats, which are more difficult to digest than unsaturated fats.

Natural role of lysolecithin in the body

Lysolecithins are not foreign compounds. They are naturally produced metabolites found throughout animal tissues and play a role in normal phospholipid metabolism.

Commercial lysolecithin products contain mixtures of phospho and lysophospholipids. Their exact composition depends on the source of lecithin and the processing conditions used during production.

Because lysolecithin already exists within the body, it is readily utilized during digestion.

Practical implications in animal nutrition

From a practical feeding perspective, the difference between lecithin and lysolecithin is functional rather than theoretical.

Lecithin provides basic emulsification support, but lysolecithin offers a more targeted and efficient solution for improving fat digestion, energy utilization, and feed efficiency.

As feed costs rise and sustainability pressures increase, maximizing nutrient utilization from every kilogram of feed becomes increasingly important. Lysolecithin helps animals extract more usable energy from the same diet, supporting both economic and environmental goals.

Although lecithin and lysolecithin are closely related, their performance in animal digestion is not the same. Lysolecithin’s smaller size, greater water affinity, and superior micelle formation make it a more effective emulsifier in the gastrointestinal tract.

For feed formulations focused on improved fat digestibility and energy efficiency, lysolecithin offers a clear advantage over lecithin.

Lecithin might sound like a modern food additive, but its story begins long before industrial nutrition. The word lecithin comes from the Greek word “lekithos”, meaning egg yolk, where it was first discovered. Even today, egg yolk remains one of the richest natural sources of lecithin.

At its core, lecithin is a group of naturally occurring fats called phospholipids. These compounds are found in both plant and animal tissues and have a unique superpower. They attract both water and fat. This makes lecithin amphiphilic, meaning it is both water loving and fat loving. That single property explains why lecithin plays such a critical role in nutrition, digestion, and cellular health.

Where Lecithin Comes From

While eggs are the best whole food source, most commercial lecithin comes from oil rich plants. Soybeans are the most common source worldwide, followed by sunflower seeds and rapeseed. In recent years, sunflower lecithin has gained popularity, especially in Europe, because sunflower is not classified as a food allergen and is not associated with genetically modified crops.

This shift is not just regulatory. It also reflects growing demand for cleaner labels and more transparent ingredient sourcing.

What Lecithin Is Made Of

Commercial lecithin, also known as E322, is a complex mixture of more than 45 naturally occurring lipids. About half of these are phospholipids, which are the most biologically active components.

All phospholipids share the property of being soluble in lipid solvents except for acetone (this property allows them to be readily distinguished from fatty acids).  Acetone insoluble (AI), expressed as a percentage, is a measure of the surface-active (functional) portion of lecithin, comprised mainly of phospholipids and glycolipids.  This fraction is also known as lysolecithin or lysophosphatidylcholine (LPC). The amount of AIs is used as a quality parameter for lecithin, with higher AIs indicating a more polar and emulsifying lecithin.

Phosphatidylserine (PS) plays a crucial role in the structure and function of cell membranes, particularly in the brain.  It plays a crucial role in the process of apoptosis, or programmed cell death.

Phosphatidic acid (PA) is an important lipid messenger and metabolic intermediate that influences diverse cellular processes through its signaling functions, effects on membrane curvature, and is the precursor for the biosynthesis of many other lipids.

The Key Phospholipids Inside Lecithin

Not all phospholipids are the same. Each plays a specific role in the body.

Phosphatidylcholine, often simply called lecithin, is the most abundant phospholipid in cell membranes. It is essential for fat digestion, bile formation, and nerve insulation. It is also the primary emulsifier that stabilizes oil in water mixtures.

Phosphatidylethanolamine supports membrane flexibility and is highly concentrated in mitochondria, where energy production takes place. It is particularly effective in water in oil emulsions.

Phosphatidylserine is critical for brain function and cell signaling and plays a key role in programmed cell death, a natural process that keeps tissues healthy.

Phosphatidic acid acts as a powerful signaling molecule inside cells and is a building block for many other lipids.

Phosphatidylinositol exists in multiple forms and is involved in insulin signaling, metabolism, stress response, and even taste perception.

Why Source Matters

The nutritional profile of lecithin depends heavily on where it comes from. Soy lecithin tends to be rich in phosphatidylcholine and contains a higher proportion of omega 6 fatty acids. Sunflower lecithin has more phosphatidylinositol and less phosphatidylethanolamine. Rapeseed lecithin typically contains higher levels of monounsaturated fatty acids, especially oleic acid, similar to rapeseed oil.

Climate, geography, storage conditions, and processing methods all influence the final phospholipid profile. Even the enzymes used during processing can change which lysophospholipids are produced.

Lecithin and Animal Nutrition

For years, the benefits of lysolecithin in animal feed were attributed mainly to phosphatidylcholine. However, newer research tells a more nuanced story.

A 2017 broiler study compared diets supplemented with purified phosphatidylcholine versus diets containing lysolecithin. The lysolecithin diets led to greater villus height in the intestine and stronger gene expression related to nutrient absorption. This showed that it is not just one molecule doing the work, but the combined action of multiple lysophospholipids that improves gut health and performance.

The Takeaway

Lecithin is far more than an emulsifier. It is a foundational nutritional building block that supports digestion, cellular integrity, energy production, and overall performance. Understanding its composition and source allows nutritionists and producers to make smarter choices that benefit both animal health and long term productivity.

In 2026, global farming and animal nutrition operate within a complex environment shaped by rising food demand, climate pressure, economic volatility, and rapid technological change. Agriculture remains a cornerstone of global food security, yet producers are required to achieve more with fewer resources while meeting stricter sustainability and animal welfare expectations. Animal nutrition has become a strategic lever for productivity, resilience, and environmental responsibility.

Production trends show continued growth in poultry and aquaculture, largely due to their efficient feed conversion and lower environmental footprint compared to other animal proteins. According to FAO and OECD outlook reports, demand for animal protein continues to rise globally, driven by population growth and urbanisation, particularly in Asia and Africa. Beef and pork production face tighter margins and higher regulatory pressure, but remain essential to regional food systems and rural economies (FAO, OECD Agricultural Outlook 2025 to 2034).

Economic pressure is one of the defining challenges for farming in 2026. Feed ingredient prices remain volatile due to climate related crop disruptions, competition from biofuel markets, and geopolitical instability affecting global trade routes. Key raw materials such as corn, soy, and fishmeal continue to fluctuate in both price and availability. According to industry analysis by Alltech and Feedinfo, feed costs remain the single largest expense for livestock producers, making feed efficiency and precision nutrition critical to farm profitability (Alltech Global Feed Survey, Feedinfo Market Reports).

Climate change is increasingly influencing farming systems worldwide. Extreme weather events such as droughts, floods, and heat stress directly affect crop yields, feed quality, and animal performance. The World Bank and FAO both highlight that climate variability is now one of the biggest risks to agricultural stability. As a result, farmers are turning to nutritional strategies that support gut health, immunity, and heat stress resilience, recognising nutrition as a frontline defense against environmental stress.

Environmental impact and sustainability expectations are reshaping livestock production. Governments, retailers, and consumers are demanding reduced emissions, improved nutrient efficiency, and greater transparency across the value chain. Livestock farming is under scrutiny for its contribution to greenhouse gas emissions and nutrient runoff, particularly nitrogen and phosphorus. This has driven innovation in feed additives that improve digestibility, reduce emissions, and support more sustainable production systems (International Feed Industry Federation, IFIF Sustainability Reports).

Animal health and biosecurity remain major concerns in 2026. Recurring outbreaks of avian influenza, African swine fever, and other diseases continue to disrupt production and trade. These challenges reinforce the importance of preventative approaches, where nutrition plays a central role in strengthening immune function and reducing reliance on antibiotics. Functional feed additives, probiotics, organic acids, and phytogenics are increasingly integrated into feeding programs to support long term health and resilience.

Despite these pressures, the animal nutrition sector continues to grow, supported by innovation and technology. Precision farming tools, digital monitoring, and data driven feed formulation are becoming more accessible across regions. According to McKinsey and StartUs Insights, precision nutrition improves feed efficiency, reduces waste, and allows producers to adapt quickly to changing conditions. These technologies help align economic performance with sustainability goals.

Sustainable feed innovation is another strong growth driver. Alternative proteins such as insect meal, microalgae, single cell proteins, and fermentation based ingredients are gaining acceptance in animal diets. These ingredients help diversify supply chains, reduce dependence on traditional crops, and lower environmental impact. Industry reports from Rabobank and the International Feed Industry Federation highlight alternative feed ingredients as a key pillar of future feed security.

Looking ahead, farming and animal nutrition in 2026 are defined by adaptation, responsibility, and opportunity. Producers who invest in advanced nutrition, sustainable practices, and resilient systems are better positioned to manage uncertainty and build long term value. As the industry balances tradition with innovation, animal nutrition remains central to building food systems that are efficient, ethical, and capable of sustaining future generations.

The type and source of dietary fatty acids have a significant impact on the carcass quality of broiler chickens. Diets that include plant oils such as rapeseed, soybean, and canola oil tend to increase the proportion of unsaturated fatty acids in the meat, including beneficial omega-3 fatty acids. These unsaturated fats enhance the nutritional value of broiler meat, making it a healthier option for consumers. However, an excessive inclusion of long-chain polyunsaturated or omega-3 fatty acids can result in off-flavors that may reduce consumer acceptance.

Animal fats, on the other hand, are known to enhance the flavor and overall palatability of meat due to their higher intramuscular fat content. While this contributes to taste and texture, it may also increase the level of saturated fats in the carcass, which are considered less desirable from a human health perspective.

The stability of fats and oils is another critical factor. Some lipids are more susceptible to oxidation, which can cause rancidity, off-flavors, and reduced shelf life of the meat. Additionally, diets rich in saturated fatty acids may lead to higher abdominal fat deposition compared to diets that use unsaturated fatty acids from plant-based oils.

Fats are insoluble in water and therefore do not naturally dissolve in the aqueous environment of the digestive system. To improve digestion and energy utilization, fats must be well emulsified. Vitalsorb Pure, an emulsifying agent containing phospholipid components, supports the formation of stable oil-in-water emulsions. This enhances the digestion and absorption of dietary fats and oils, especially saturated fats, resulting in better feed efficiency and carcass quality.

An effective fat and oil supplementation program should balance nutritional composition, production efficiency, and cost-effectiveness. Each farm has unique nutritional needs and production goals, so it is recommended to consult with animal nutrition professionals to tailor feeding strategies for optimal results.

In broiler production, fats and oils are often seen simply as concentrated sources of energy but their impact reaches much further. The right balance of lipids can enhance carcass quality, optimize yield, and even influence meat composition and consumer satisfaction.

We continue to study how smarter fat nutrition not only fuels growth but also supports sustainability and long-term animal health.

1. Fatty Acid Composition

The type of dietary fat directly determines the fatty acid profile of broiler meat. Diets high in polyunsaturated fatty acids (PUFAs) such as flaxseed or canola oil can increase the levels of beneficial omega-3 fatty acids, improving the nutritional value of poultry meat. These fatty acids contribute to healthier products for consumers, without compromising carcass yield or dressing percentage.

2. Carcass Yield and Dressing Percentage

Research consistently shows that supplementing broiler diets with appropriate lipid levels can improve carcass yield and dressing percentage. Optimized fat inclusion supports better energy utilization, muscle growth, and overall feed conversion efficiency.

3. Reduction of Abdominal Fat

One of the key benefits of replacing saturated fats (like tallow) with unsaturated oils lies in reduced abdominal fat deposition. Unsaturated fats stimulate fatty acid β-oxidation and inhibit fat synthesis, resulting in leaner carcasses and more efficient feed utilization.

4. Oxidative Stability

While unsaturated fats enhance the fatty acid profile, they are also more susceptible to oxidation, which can shorten shelf life and affect meat flavor. Balancing fat sources with dietary antioxidants is critical to maintaining meat stability and quality throughout storage.

5. Water Holding Capacity and Juiciness

Although dietary lipids may not significantly change water-holding capacity, their inclusion can influence juiciness and cooking loss, improving the sensory appeal of poultry meat — particularly in premium markets where eating quality matters.

The Role of Emulsification

Because fats are insoluble in water, their digestion depends on efficient emulsification within the gastrointestinal tract. Well-emulsified fats are easier to digest and absorb, providing more usable energy to the bird.

That’s where Vitalsorb™ Pure, comes in an advanced phospholipid-based emulsifier formulated by GN Good Nutrition.
Vitalsorb™ Pure promotes stable oil-in-water emulsions, improving the digestion and absorption of dietary fats and oils, especially saturated fats. The result? Better feed efficiency, higher energy yield, and improved carcass quality naturally.

Balancing Efficiency and Sustainability
