Saccharomyces cerevisiae extract, also known as yeast extract, yeast extract powder, and yeast extract, uses molasses yeast or beer yeast as raw materials and undergoes autolytic enzymatic hydrolysis, centrifugal separation, concentration, and spray drying to obtain a powdery product.
Product model and characteristics
Application
An ideal source of small peptide protein for livestock, poultry, aquatic products and other animals.
Product efficacy
- Taste-presenting nucleotides can greatly improve the palatability of feed and increase its food attraction.
- Yeast-derived glutathione improves the antioxidant capacity of animals, promotes animal health, and resists stress and disease invasion.
- Yeast nucleic acids and nucleotides promote animal growth and improve immunity.
- Small peptide nutrition promotes protein absorption and conversion, improves feed return, and is an ideal choice for low-protein dietary ingredients.
Usage and dosage
1. In pig feed education and protection feed, use 1.0%-5.0%. Used in conjunction with egg powder, plant hydrolyzed protein, fish slurry, etc., excellent feeding and health care effects can be obtained.
2. Meat poultry: 1‰-2‰, directly added to compound feed to reduce the feed-to-meat ratio and improve survival rate. 3. Aquatic products: 1%-5%, directly added to compound feed to promote feed intake, reduce feed coefficient, improve survival rate, and replace high-priced protein raw materials. Upgrade feed from quantitative nutrition to functional nutrition.
