What is yeast hydrolysate?
Yeast hydrolysate, which is also called autolyzed yeast, is a protein and nucleic acid source for the feed, obtained from natural active yeast, hydrolyzed by endogenous enzymes (intracellular autolyze) and exogenous enzymes, it is considered is external digestion of protein and nucleic acid source come from the yeast.
Yeast hydrolysate can be used as an innovative functional protein or for animal protein substitution in reformulation strategies
Yeast hydrolysate is rich in protein-nucleic acid, active peptides, amino acids, and rich B vitamins, and contains a certain amount of cell wall polysaccharides.
What is important in yeast Yeast hydrolysate besides protein? -Nucleic acid
Yeast hydrolysate is a kind of RNA source of feed, Nucleic acid in the yeast hydrolysate is rich to more than 7%, high-quality yeast hydrolysate is richer Nucleic acid which can be rich to 10%.
Nucleic acids or nucleotides are generally not considered essential nutrients, but when animals are stressed, nucleotides can Supplement the deficiency of endogenous nucleotide synthesis, accelerate the replication, division, and proliferation of body cells, stimulate the production potential of animals, promote the development of the immune system, prevent diseases, and improve the anti-stress ability and comprehensive immune level of animals.
Why nucleotides is needed for poultry?
Nucleotides are continuously synthesized and degraded in the body, and there are two main ways of their synthesis: one is the de novo synthesis pathway (De novo synthesis): some amino acids (glutamine, aspartic acid, glycine) are synthesized in the body. ), formate and carbon dioxide are used as raw materials for de novo synthesis; the second is the salvage pathway
(Salvage): phosphoribosylation occurs between phosphoribosyl in the organism and the free bases generated by the hydrolysis of exogenous nucleic acids and nucleotides, thereby synthesizing the corresponding Nucleotides.
Many tissues (small intestine, large intestine, lymph) and cells (erythrocytes, leukocytes, bone marrow cells) with vigorous growth and metabolism in the body have limited ability to synthesize nucleotides de novo, especially when animals are subjected to immune stress, liver damage, starvation, and rapid growth. In this case, endogenous synthetic nucleotides cannot meet the needs of the body, and exogenous nucleotides need to be supplemented. Therefore, the value of exogenous nucleotides is reflected in the “raw materials of the salvage pathway”, which can meet the needs of nucleotides in the special state of animals.
Poultry is considered a fast-growth farming animal, like recessive white feather chicken, which is expected to sell after bout 42 days of growth, the gut of poultry that grows fast has more Nucleotides requirement in feed because synthesis from other materials is energy-consuming.
In the trial on Hiyeast© yeast hydrolysate on boiler recessive white feather chicken, 800gram /ton of yeast hydrolysate is added in feed on the full process of boiler growth. The picture of
intestinal tract showed the better growth of the Villus Height in the hi yeast hydrolysate group, also the yeast hydrolysate group have a better performance.
The trial of Hiyeast© Autolyzed yeast is carried out in Shangdong, china by 4 control groups and 3 groups of Yeast hydrolysate, 12 thousand boilers in one group,
When 42 passes, the survival rate of Autolyzed yeast group is 92.64% while the control group is 86.05% only.
What is the benefit of yeast hydrolysate in feed for poultry?
Application in Broiler of yeast hydrolysate
- Significantly increase the growth rate, increase the slaughter weight, and reduce the feed /meat ratio
- Reduce stress, stabilize production, and stabilize feed quality
- Improve the uniformity of Broiler quality before slaughter
Application in layer and breeder of yeast hydrolysate
- Reduce the adverse effects of stress (hot weather, water, and power outages), and stabilize production
- Extend the peak of egg production, thereby increasing the egg production rate
- Increase egg uniformity
- On Breeder, it can increase the rate of qualified eggs, the rate of fertilized eggs, and the hatching rate
What is the dose of yeast hydrolysate on poultry?
To reach the benefit above, we recommend you add the dose as follows, mixed in the ration of poultry:
|Recommended dose, kg / ton||0.8-1.0||0.5-0.8||1.5|
