Poultry products, including meat and eggs, are among the most widely consumed animal-derived foods globally, providing high-quality protein and essential nutrients. Over the past 50 years, the demand for poultry has steadily risen, with consumption expected to continue increasing. As a result, improving the efficiency of poultry production has become a central focus in the industry. Recent studies have shown that yeast cultures, such as YeaFerm EX100, offer numerous nutritional and health benefits for poultry. YeaFerm EX100 is a high-quality yeast culture produced using advanced biotechnological fermentation processes. It contains a range of beneficial yeast extracellular metabolites, including nucleic acids, polysaccharides, proteins, peptides, enzymes, vitamins, and organic acids, as well as yeast cell contents and post-fermentation raw materials. These components work together to enhance feed utilization, boost disease resistance, and stimulate the olfactory and taste systems of poultry.
1.Key Functions of YeaFerm EX100 for Poultry
1.1 Promoting Nutrient Digestion and Absorption
Organic acids like lactic acid and malic acid in YeaFerm EX100 help to create a favorable gastrointestinal environment by stabilizing pH levels and improving the microbial structure within the gut. These acids promote the growth of beneficial bacteria, such as lactic acid bacteria and cellulolytic bacteria, increasing the effective concentration of probiotics. This results in better digestion, absorption, and overall utilization of nutrients, which enhances production performance.

1.2 Adsorbing Pathogens and Boosting Disease Resistance
YeaFerm EX100's ability to adsorb pathogens and modulate immune functions is attributed to its functional components, such as mannan oligosaccharides and β-glucans. Mannan oligosaccharides resemble pathogen receptors in the intestinal tract, preventing pathogen adhesion to intestinal villi. β-glucans, on the other hand, stimulate the production of IgG immunoglobulins by binding to complement receptors on immune cells, thereby enhancing the overall immune function of the poultry.

1.3 Nutritional Supplementation and Host Nutrient Metabolism
YeaFerm EX100 contains bioactive substances such as B-vitamins, amino acids, oligosaccharides, nucleotides, digestive enzymes, volatile fatty acids, and potential growth factors. These components play a vital role in improving the nutritional quality of feed, enhancing nutrient metabolism in poultry, and supporting optimal animal performance.

2. Application in Broilers
2.1Enhancing Growth Performance
In a study with Cobbe broilers fed a diet supplemented with 0.5% and 1% YeaFerm EX100 over 42 days, results showed a significant reduction in feed-to-gain ratio (F/G) and an increase in the European performance index. Additionally, the average daily gain (ADG) in the 0.5% and 1% YeaFerm EX100 groups was increased by 2.1g and 0.8g, respectively.

3. Application in Layer Hens
3.1 Improving Production Performance of Laying Hens
A study conducted with 720 layer hens allocated to three dietary treatments over 42 days revealed that supplementation with 0.1% YeaFerm EX100 resulted in a 0.36% increase in average egg weight. The feed-to-egg ratio was reduced by 3.37% and 5.29% in the 0.1% and 0.2% YeaFerm EX100 groups, respectively. Additionally, the laying rate in the 0.2% YeaFerm EX100 group increased by 2.0%.
Conclusion
The addition of YeaFerm EX100 to poultry diets proves to be an effective strategy for improving growth performance, boosting disease resistance, and enhancing overall productivity. Its ability to improve nutrient absorption, support immune functions, and provide essential bioactive components makes it a valuable addition to poultry feed formulations, benefiting both broilers and layer hens.
