What is autolyzed yeast?
Autolyzed yeast, also called hydrolyzed yeast, is a selected strain of Saccharomyces cerevisiae produced through liquid fermentation. After autolysis or catalytic hydrolysis with exogenous enzymes, followed by concentration or drying, the nutritional value of the yeast is significantly enhanced. Autolyzed yeast extract is rich in mannan oligosaccharides, nucleic acids, nucleotides, small peptides, digestive enzymes, free amino acids, and B vitamins, making it easier for young animals to digest and absorb.
Autolyzed yeast is one of the best sources of functional hydrolyzed protein for animals.

1). Fresh molasses and pure yeast culture are used as raw materials.
2). Strong feed palatability. Easily digested and absorbed by young animals.
3). Rich in nucleotides, small peptides, digestive enzymes, amino acids, and vitamins.

For Swine:
Hydrolyzed yeast for swine can stimulate feed intake in sows, support intestinal health, improve reproductive performance, increase milk production, and reduce postpartum infections.
Reduce mortality and partially or completely replace plasma protein powder without affecting weight gain.
For Poultry:
Autolyzed yeast for poultry can provide exogenous nucleic acids to meet the animal’s nucleic acid requirements during immune stress, liver damage, and rapid growth when endogenous nucleotide synthesis is insufficient.
It promotes small intestine development, improves intestinal morphology, enhances digestion and absorption functions, reduces mortality, and improves feed conversion ratio.
For Aquatic Products:
Autolyzed yeast for aquatic animals can improve feed intake. Rich in flavor nucleotides (L+G) and aromatic amino acids, it can significantly enhance feed palatability.

Packaging: 25kg bag / ton bag, OEM label available.
Storage: Store in a cool, dry place away from direct sunlight.
As a new type of single-feed material, hydrolyzed yeast is a hydrolyzed protein. It has strong feed-attracting effects and is easily absorbed by young animals. Feed-grade dry yeast hydrolysate supports intestinal morphology, regulates intestinal microflora, reduces diarrhea, and significantly improves immunity. It is an additive capable of replacing plasma protein powder. With the high prices of fish meal and plasma protein powder, along with increasing biosecurity concerns, feed-grade yeast hydrolysates have broad market prospects.
