What are the advantages of beer yeast compared to other feed additives?

      As a natural feed additive, beer yeast has advantages in functional diversity, safety, nutritional synergy, and other aspects compared to antibiotics, single probiotics, enzyme preparations, chemically synthesized additives, etc., as follows:

1. More comprehensive functions, with dual functions of nutrition and regulation

      The composition of beer yeast is complex and rich, containing high-quality protein (40% -50%), amino acids (rich in lysine and methionine), B vitamins (B1, B2, folic acid), minerals (selenium, zinc, iron), as well as prebiotics (oligosaccharides, β - glucans), probiotics (live or inactivated metabolites), enzymes (amylase, protease) and other bioactive substances.

      Compared to a single probiotic (such as lactic acid bacteria): it can only supplement specific microbial communities, while beer yeast can regulate microbial communities through live bacteria, promote the proliferation of local beneficial bacteria through prebiotics, and provide nutrition, achieving a dual effect of "nutrition+health".

      Compared to enzyme preparations (such as phytase): they can only assist in digesting specific nutrients, while the enzymes and nutrients of beer yeast work together to improve feed digestibility and reduce nutrient deficiencies.

      Compared to mineral/vitamin additives, chemically synthesized minerals (such as inorganic selenium) have lower absorption rates, while minerals in beer yeast exist in organic forms (such as yeast selenium and yeast zinc), with higher bioavailability and no risk of excessive poisoning.

2. Higher safety, no residual or antibiotic resistance risks

      Beer yeast is derived from beer brewing by-products and belongs to natural microbial metabolites. After processing, its safety has been verified for a long time:

      Compared to antibiotics: Although antibiotics can inhibit pathogenic bacteria, long-term use can lead to bacterial resistance and drug residues (such as antibiotic residues in chicken and pork), posing a threat to food safety; And beer yeast has no residue problem and does not induce drug resistance, which is in line with the trend of "antibiotic free farming".

      Compared with chemically synthesized additives (such as growth promoters and antioxidants): Some chemical additives (such as certain antibiotic substitutes) may have liver and kidney function burdens or potential toxicity, while beer yeast metabolites (such as organic acids and short chain fatty acids) have no toxic side effects on livestock and poultry and are suitable for long-term addition.

3. Gentle and long-lasting regulation of gut microbiota

      The regulation of gut microbiota by beer yeast is not achieved through "competitive inhibition of pathogenic bacteria" (such as the killing effect of antibiotics), but through multiple mechanisms to achieve balance:

      The oligosaccharides it contains can adsorb pathogenic bacteria (such as Escherichia coli and Salmonella) in the intestine, reducing their colonization;
β - glucan can promote the activity of intestinal mucosal immune cells (such as macrophages) and enhance intestinal barrier function;

Metabolites (such as organic acids) can regulate intestinal pH and create a suitable environment for beneficial bacteria such as lactic acid bacteria.

      Compared to antibiotics: Antibiotics indiscriminately kill beneficial bacteria, leading to an imbalance in gut microbiota (such as "secondary infections"), while beer yeast only inhibits pathogenic bacteria and promotes beneficial bacteria, with less interference to the microbiota and longer lasting effects (prebiotics can continue to function).

4. Widely sourced, cost controllable, and environmentally friendly

      Beer yeast is a byproduct of beer brewing, which can be processed through drying, inactivation, and other processes to be used as a feed additive. It belongs to resource recycling and has a lower raw material cost than most imported probiotic preparations or chemically synthesized additives.

      Compared to expensive functional additives such as certain imported enzyme preparations and plant extracts, beer yeast has a higher cost-effectiveness and is suitable for large-scale livestock and poultry breeding applications;

      Compared to mineral salt additives (such as inorganic iron and copper), organic minerals in beer yeast have no environmental residues after metabolism (such as reducing soil pollution caused by copper and zinc in feces), which is more in line with environmental requirements.

5. More adaptable and less affected by external conditions

      Compared with live bacterial preparations (such as Bacillus subtilis): the active ingredients in beer yeast (such as oligosaccharides and β - glucans) have stronger tolerance to high temperatures, stomach acid, and feed processing (granulation, mixing), and are less prone to deactivation; Even inactivated beer yeast can still produce metabolites such as short chain fatty acids and vitamins.

      Compared to specific enzyme preparations (such as cellulases): they can only decompose specific substrates, while the complex enzyme system in beer yeast can synergistically act on various nutrients such as carbohydrates and proteins, adapting to different feed formulations (such as corn soybean meal type and miscellaneous meal type feed).

6. Reduce negative effects and align with the trend of green farming

      Avoiding the drawbacks of antibiotic abuse, such as weakened immunity of livestock and poultry, drug residues in products, environmental pollution, etc;

Relieve the limitations of single nutritional additives, such as metabolic burden caused by excessive addition of amino acids and intestinal damage caused by high copper and zinc.

      Beer yeast fundamentally improves the health of livestock and poultry through the synergistic effect of "nutrient supply+microbial community regulation+immune enhancement", rather than simply "promoting growth", which is more in line with the requirements of modern animal husbandry for "green, safe, and efficient".

summarize

      The core advantage of beer yeast lies in the combination of "naturalness, multifunctionality, safety, and economy": it is not only a nutritional supplement, intestinal regulator, or immune enhancer, but also has minimal side effects and strong adaptability. Therefore, it has irreplaceable value in replacing antibiotics, optimizing feed formulations, and improving breeding efficiency. However, its effectiveness needs to be designed comprehensively based on the dosage, livestock and poultry breeds, and physiological stages in order to maximize its advantages.
