Yeast hydrolysate refers to the product obtained by using yeast as a strain, through fermentation, and then after enzymatic hydrolysis, the resulting material is concentrated and dried. Yeast hydrolysate is rich in protein, polysaccharide, RNA, and other substances. It can be used in feed to improve the immunity of animals and is an excellent feed material.

The 3 core nutrients of yeast hydrolysate

1. Proteins

It can participate in the maintenance of normal barrier function, increase the growth rate of animals, increase the weight of slaughter meat, and can be used as a supplement for amino acids, peptides, and other substances.

2. Polysaccharides (MOS, β-glucan)

It can adsorb and take away pathogenic microorganisms and mycotoxins, and improve the body’s immune response.

3. RNA and Nucleotides

The nucleotides in yeast hydrolysate have important nutritional effects on animals, especially young animals. Studies have shown that nucleotides can enhance the body’s immunity, promote cell regeneration and repair, promote the normal development of the intestinal tract of juvenile animals, resist oxidation, and maintain normal intestinal flora. In addition, the inosinic acid and bird Glycolic acid can be used as an umami-enhancer and flavor enhancer and plays a good role in promoting animal feeding.

Zhen-Ao Bio-Tech has many different types of yeast hydrolysate products. Among them, ZNA12 yeast hydrolysate contains up to 11.5% or more nucleotides and is rich in protein. It has a good effect on improving the immunity of farmed animals when used in feed products.

Yeast hydrolysate is a high-quality protein feed ingredient. The apparent digestible energy and apparent metabolic energy of yeast hydrolysate on piglets are 14.98MJ and 14.05MJ, respectively, which are higher than the corresponding parameters of fish meal and soybean meal. The protein digestion and utilization rate are high. The piglet’s true digestibility of crude protein is 89.71%, and the true utilization rate is 69.53%. The yeast hydrolysate will be hydrolyzed into small peptides, dipeptides, and tripeptides, which are easy to digest.

Crude Protein, RNA, Nucleotide

The ribonucleic acid content of ZNA12 is above 20.0%, and its nucleotide content is greater than 11.5%, and the nucleotide content of the equivalent product of other competitors is about 5.0-8.0%. Such abundant mononucleotides occur naturally in the feed, eliminating the need for the animal’s own enzymatic hydrolysis process and can be directly digested and absorbed. The advantage is that it has less loss but more effective. The nucleotide C and U of ZNA12 yeast hydrolysate are above 2.50%, and A and G are above 3.30%.

RNA and nucleotides play a vital role in the growth of cultured animals. Exogenous nucleotides can promote the growth and development of the small intestine, and affect the intestinal microbial system; nucleotides can participate in regulating liver protein synthesis and maintaining liver It also has the normal function of the animal; it also has the functions of enhancing animal immune function, scavenging free radicals and anti-oxidation. The content of nucleotides in conventional feed is very low, and additional exogenous nucleotides need to be added to meet animal needs. Yeast hydrolysate is a good choice for the supplementation of exogenous nucleotides. The digestion of yeast nucleic acid by the animal body relies on the combined action of a variety of nucleases in the digestive tract. The exogenous nucleic acid ingested by animals can be degraded into single nucleotides under the catalysis of pancreatic nuclease, and further degraded into purine bases by nucleases. Base or pyrimidine base, ribose-5′ phosphate, which quickly enters the body’s metabolic process, as shown in the figure below:

Enzyme, RNA, and Nucleotide

Yeast nucleotides have many benefits when blended in the feed. Among them, 5′-inosinic acid (IMP) and 5′-guanylic acid (GMP) have a strong umami taste, which can enhance feeding stimulation and increase the umami taste of feed geometrically, equivalent function to umami enhancers. Nucleotides A, G, C, and U can participate in tissue development and system regulation in new breeding animals; secondly, under extreme stress conditions, such as growth, breeding, environmental challenges, disease resistance, and injury recovery Etc.  Trillions of additional nucleotides must be ready for cell proliferation at any time. Exogenous addition of nucleotides can well ensure its normal physiological functions; nucleotides can also promote the elongation of intestinal villi. Increase the surface activity of the gastrointestinal tract, promote the rapid propagation of intestinal flora, and promote the growth of beneficial bacteria; nucleotides can also promote the maturation of T cells of the immune system in the body, significantly accelerate the rise of IgG plasma levels, and thus improve the immune response.

It is safe to say that ZNA12 yeast hydrolysate can be used as a good new feed source of exogenous nucleotides for animal stress, rapid growth and disease prevention, and can be used in feed to meet the needs of animal nucleotides and its important physiological functions.
