Biological protein feed prepared from waste vinasse of Jimo rice wine and preparation method of biological protein feed

The invention belongs to the technical field of microbial fermentation engineering, and particularly relates to biological protein feed prepared from waste vinasse of Jimo rice wine and a preparation method of the biological protein feed. The rice wine vinasse and peanut skin are screened under fermentation conditions, so that the palatability, the acid soluble protein content and the protein digestion utilization rate are improved, and anti-nutritional factors are decomposed to a certain extent. The two raw materials are compounded and fermented, amino acid composition is complementary and improved, the content of crude protein, lysine, methionine and crude fiber can be complementary, and the nutritional value and the feeding value are improved. By applying the product, the breeding cost can be reduced, and the income can be increased; through enzyme treatment and fermentation, the feed contains a large number of probiotics and is rich in growth factors, peptides and the like, the health level of animal bodi
