1、 Nutritional characteristics of beer yeast

Saccharomyces cerevisiae is a byproduct of the brewing industry, rich in:

High quality protein (40-50%): contains all essential amino acids

B vitamins (riboflavin, niacin, etc.)

Minerals (potassium, magnesium, zinc, etc.)

Active ingredients (β - glucan, mannan)

Digestive enzymes (amylase, protease)

2、 Core benefits for farmed animals

Improve feed conversion efficiency

Experimental data shows that adding 0.2% beer yeast to broiler feed reduces the feed to meat ratio by 5-8%

Mechanism of action:

Supplementing endogenous enzyme deficiencies and promoting the breakdown of macromolecular nutrients

Improve intestinal villous structure (scanning electron microscopy observation shows a 15% increase in villous height)

Enhance animal immunity

Immune regulatory substances:

β - glucan: activates macrophage activity (increases phagocytic index by 20-30%)

Mannan: adsorbs intestinal pathogens (such as Escherichia coli and Salmonella)

Clinical case: piglet diarrhea rate reduced by 40%, survival rate increased by 8-12%

Improve the quality of livestock products

Pork: Increased intramuscular fat content by 0.5-1.2%, improved marble pattern score

Eggs: darkened yolk color (2-3 levels higher with Roche color fan)

Milk: Milk fat percentage increased by 0.15-0.3%, somatic cell count decreased by 25%

Promote animal growth and development

Improved growth performance:

Weaned piglets increase daily weight gain by 7-10%

The average daily weight gain of beef cattle increased by 0.1-0.2kg

Action path:

Promote the secretion of insulin-like growth factor (IGF-1)

Optimize the structure of gut microbiota (increase the number of lactic acid bacteria by 3 times)

3、 Application solutions for different breeding scenarios

Main benefits	adding proportion	aquaculture types
Piglet care	0.3-0.5%	reduction of weaning stress, prevention of diarrhea
Egg laying chicken farming	0.2-0.3%	improves eggshell quality and prolongs peak egg production
Dairy farming	0.5-1.0%	to increase milk production and alleviate heat stress
Aquaculture	0.5-1.5%	enhances disease resistance and improves meat quality

4、 Economic Benefit Analysis

Feed cost savings: replacing some soybean meal (cost reduction of 0.05-0.1 yuan/kg feed)

Reduce medication costs: reduce antibiotic usage by 30-50%

Product premium space: Price increase of 5-15% for high-quality livestock products

Typical case: A 10000 head pig farm achieves an annual efficiency increase of 800000 to 1.2 million yuan

5、 Precautions for use

Quality control: Choose products that are dry (moisture<8%) and highly active (≥ 10 ^ 8 CFU/g)

Add gradient: It is recommended to gradually transition from 0.1% to the recommended amount

Compatibility taboos: Avoid direct mixing with strong acids and bases

Storage conditions: Store in a cool and dry place, with a shelf life of 6-12 months

6、 Industry Development Trends

Collaborative application of microecological agents: compounding with lactic acid bacteria and Bacillus subtilis

Targeted functional development: breeding of high-temperature resistant strains and high enzyme activity strains

Environmental Value Extension: Used for aquaculture wastewater treatment (COD removal rate increased by 40%)

conclusion

Beer yeast, as a natural functional feed additive, has demonstrated multiple values in improving breeding efficiency, ensuring food safety, and promoting green farming. With the deepening of research and the improvement of technology, its application scenarios will continue to expand, providing strong support for the sustainable development of modern animal husbandry.
