Abstract

The invention provides a preparation method of a feed protein raw material. The method comprises the steps of preparing an aspergillus oryzae culture; preparing antibacterial peptide fermentation liquid; uniformly mixing the aspergillus oryzae culture with the antibacterial peptide fermentation liquid, adding molasses, and performing anaerobic fermentation or facultative anaerobic fermentation toobtain fermented feed protein raw materials; and drying the fermented feed protein raw materials, and performing crushing to obtain feed protein raw materials. According to the method, high-molecular-weight proteins in the raw materials can be degraded into components of low-molecular-weight proteins, small peptide and amino acids, digestion and utilization by animals are facilitated, besides, antigen proteins in the raw materials are degraded, and the protein of the proteins is improved. In addition, the antibacterial peptide fermentation liquid is also added to the feed protein raw materialsfor mixed fermentation, high content of soluble proteins in the feed protein raw materials is guaranteed, certain bacterium resisting efficacy of the feed protein raw materials are given, and the palatability of the feed protein raw materials is not influenced.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a method for preparing feed protein raw materials. Background technique [0002] Soybean meal and bran contain anti-nutritional factors such as glycinin and phytic acid, which have the advantages of relatively low price and not easy to be oxidized and corrupted. In addition, they are rich in amino acid types and content, especially lysine, which is relatively lacking in other plant feeds. Its content is as high as 2.5%-2.8%, and it is widely favored in animal husbandry. However, soybean meal and bran are directly used as feed raw materials. The large amount of macromolecular protein in them is not conducive to the digestion and utilization of animals, and the antigenic protein in the raw materials cannot be degraded. Therefore, continuous processing is required to make the raw materials have higher feed value. . [0003] In addition, with the rapid development of science and techn...
