Analysis of the Application Value and Function of Beer Yeast Powder in Chicken

Analysis of the Application Value and Function of Beer Yeast Powder in Chicken Farming Industry

      With the increasing demand for efficient, ecological, and healthy development in modern aquaculture, the scientific application of feed additives has become the key to improving aquaculture efficiency. Beer yeast powder, as a natural nutritional supplement, has gradually gained attention in the chicken industry due to its unique ingredients and functions. This article will systematically analyze the role and practical application value of beer yeast powder in chicken farming from the perspectives of nutrition, health, and production efficiency.

1、 Composition and Characteristics of Beer Yeast Powder

      Beer yeast powder is a byproduct of the beer brewing process, mainly made by inactivating and drying brewing yeast (Saccharomyces cerevisiae). Its core components include:

      Protein and amino acids: The crude protein content is as high as 40% -50%, rich in 18 types of amino acids (including essential amino acids such as lysine and methionine);

      B vitamins: such as vitamin B1 B2、B6、 Niacin, folic acid, etc;

      Minerals and trace elements: including zinc, selenium, iron, calcium, magnesium, etc;

      Functional ingredients: β - glucan, oligosaccharides, nucleic acids, enzymes and other active substances.

      These ingredients endow beer yeast powder with various potential applications in chicken farming.

2、 The role of beer yeast powder in chicken farming

1. Supplement nutrition and promote growth

      High quality protein source: Beer yeast powder has a high protein content and high digestibility (about 90%), which can provide essential amino acids for chicken flocks, compensate for the lack of amino acids in conventional feed (such as corn and soybean meal), promote muscle development and weight gain.

      Synergistic effect of vitamins and minerals: B vitamins participate in energy metabolism, while elements such as zinc and selenium enhance enzyme activity, jointly improving feed conversion rate. Research has shown that adding 2% -3% beer yeast powder to the diet of chicks can significantly increase their weight gain rate by 10% -15%.

2. Enhance immunity and reduce the occurrence of diseases

      The immunomodulatory effect of β - glucan: β - glucan can activate chicken immune cells (such as macrophages and natural killer cells), enhance antiviral and bacterial infection resistance.

      The antibacterial function of mannan oligosaccharides: By competitively inhibiting the colonization of harmful bacteria (such as Salmonella and Escherichia coli) in the intestine, it maintains the balance of gut microbiota.

      Antioxidant protection: Components such as selenium and vitamin B2 can eliminate free radicals and reduce the negative effects of stress reactions (such as high temperature and herd switching) on chicken flocks.

3. Improve intestinal health and increase digestion and absorption rate

      Promoting the proliferation of beneficial bacteria: Oligosaccharides and dietary fiber in beer yeast powder are "prebiotics" for lactic acid bacteria and bifidobacteria, which can optimize the gut microbiota.

      Enzyme assisted digestion: Enzymes in yeast cell walls, such as phytase, can break down indigestible phytate phosphorus in feed, improve phosphorus utilization, and reduce fecal pollution.

      Repairing intestinal mucosa: Amino acids such as glutamine help repair damaged intestinal epithelial cells and reduce the incidence of diarrhea.

4. Improve the production performance of laying hens

      Extending the peak period of egg production: B vitamins and organic selenium can improve the reproductive function of laying hens, increase egg production rate and eggshell quality.

      Improving Egg Yolk Nutrition: Eggs produced by laying hens with added beer yeast powder have significantly increased selenium and vitamin B12 content in their yolks, resulting in higher nutritional value.

5. Reduce breeding costs and decrease antibiotic dependence

      Beer yeast powder can partially replace high priced protein raw materials such as fish meal and soybean meal, reducing feed costs.

      By enhancing immunity and intestinal health, reducing the use of antibiotics, it is in line with the trend of green farming.

3、 Usage and precautions of beer yeast powder

Addition amount:

      Chicks: 1% -2% of the diet;

      Breeding chickens: 2% -3% of the diet;

      Egg laying hens/breeder chickens: 3% -5% of the diet.

      Usage: Mix directly into the feed or mix with warm water before mixing, avoiding high temperature heating that can damage the active ingredients.

matters needing attention:

      Choose inactivated yeast powder produced by legitimate manufacturers to avoid contamination by live bacteria;

      When using it for the first time, gradually increase the dosage to prevent discomfort in the intestines of the chicken flock;

      Store in a moisture-proof and light proof manner, and use as soon as possible after opening.

4、 Practical application cases

      After adding 4% beer yeast powder to the feed of a large-scale egg laying chicken farm, the egg production rate increased by 8%, the egg breakage rate decreased by 30%, and the mortality rate caused by intestinal diseases decreased by 50%. Another broiler experiment showed that the experimental group with 3% beer yeast powder was slaughtered 3 days earlier than the control group, and the feed to meat ratio decreased by 0.2.

5、 Conclusion

      Beer yeast powder, with its comprehensive nutrition and diverse functions, has shown significant growth promoting, disease resistant, and quality enhancing effects in the chicken industry. With the increasing demand for safe poultry products among consumers, the promotion and use of beer yeast powder as a natural additive not only conforms to the concept of healthy farming, but also provides economically feasible solutions for farmers. In the future, by further optimizing the addition scheme and conducting in-depth research on its mechanism of action, the application prospects of beer yeast powder will be even broader.

      By scientifically applying beer yeast powder, the chicken industry is expected to achieve a win-win situation of economic and ecological benefits.
