The invention relates to the field of application of microorganisms, in particular to a nucleotide-type yeast hydrolyzate for feed and a preparation method and application thereof. The yeast hydrolyzate of the present invention is obtained by yeast milk autolysis and compound enzyme enzymolysis, the yeast hydrolyzate comprises protein, nucleic acid and nucleotides, and the nucleotides are non-exogenous and are dried with yeast hydrolyzate. In terms of substance mass, the content of the protein is ≥48%, the content of the nucleic acid is ≥10%, and the content of the nucleotide is 1.8-2.5%. The present invention also provides a method for preparing the above yeast hydrolyzate. The yeast hydrolyzate obtained by the present invention contains nutrients such as crude protein, amino acids, small peptides, nucleic acids and nucleotides, and can improve the nutrition of protein raw materials when used in feed. At the same time, it does not need to add exogenous nucleotides, which can meet the nutritional value of protein raw materials of farmed animals. |
