Feed-Grade Yeast Cell Wall: A Promising Ingredient for Livestock Nutrition

0 Author 2023-09-22 08:39:12


Feed-grade yeast cell wall is gaining recognition in the livestock industry as a valuable ingredient in animal nutrition. Derived from the outer layer of yeast cells, it offers several benefits such as improved gut health, enhanced immune response, and increased overall performance. This article aims to explore the potential applications and advantages of using feed-grade yeast cell wall in livestock feed.

1. Gut health improvement:

Feed-grade yeast cell wall contains a high concentration of mannan-oligosaccharides (MOS), which act as prebiotic compounds in the gut. MOS promotes the growth of beneficial bacteria, such as Lactobacillus and Bifidobacterium, while inhibiting the growth of harmful pathogens. This modulation of gut microbiota improves digestion, nutrient absorption, and reduces the risk of digestive disorders in livestock animals.

2. Enhanced immune response:

The beta-glucans present in feed-grade yeast cell wall have immunostimulatory properties. They activate immune cells, such as macrophages and natural killer cells, leading to an improved immune response in animals. This helps in the prevention and control of various diseases, ultimately contributing to better overall health and productivity in livestock.

3. Mycotoxin binding:

Yeast cell wall components, particularly the mannan-oligosaccharides, have the ability to bind with mycotoxins present in animal feed. Mycotoxins are toxic substances produced by molds that can adversely affect animal health and performance. By binding to mycotoxins, feed-grade yeast cell wall reduces their absorption in the gut, minimizing their detrimental effects on livestock animals.

4. Improved nutrient utilization:

Feed-grade yeast cell wall acts as a beneficial fiber source in animal diets. It helps in the breakdown of complex carbohydrates and fiber, improving nutrient availability and absorption. This results in increased feed efficiency and better utilization of dietary protein and energy, leading to improved growth and performance in livestock animals.

5. Stress reduction:

Livestock animals often face various types of stress, such as weaning, transportation, and environmental changes. The inclusion of feed-grade yeast cell wall in their diet has been shown to alleviate stress by improving gut health and modulating the immune response. This leads to reduced incidences of stress-related complications and better adaptation to stressful conditions.


Feed-grade yeast cell wall offers several advantages in livestock nutrition, including improved gut health, enhanced immune response, mycotoxin binding, improved nutrient utilization, and stress reduction. Its inclusion in animal feed formulations can have a positive impact on animal performance, health, and overall productivity. However, it is essential to consider the appropriate quantity and quality of feed-grade yeast cell wall to maximize its benefits. Further research and application trials are needed to optimize its utilization in different livestock species and production systems
