A kind of fermentation process of bacteria enzyme feed

Abstract

This application relates to the field of microbial fermentation, and specifically discloses a fermentation process of bacterial enzyme feed, including the following steps: S1, preparing koji, dissolving the koji to obtain feed seed liquid; the koji is composed of koji materials and mixed bacteria powder; the mixed bacteria powder is composed of yeast powder and Bacillus subtilis powder; S2, the feed seed liquid prepared in S1 is stirred and fermented at 28-38°C for 68-78h, and then fermented at 47-58 Stir and dry for 32-40 hours under the condition of ℃ to prepare the finished bacterial enzyme feed; the bacterial enzyme feed has good storage stability in a higher temperature environment, even if the animal cannot eat it all at once, the remaining bacterial enzyme feed is exposed to relatively high temperature. Under high ambient temperature, the nutrients in the remaining bacterial enzyme feed still have good biological activity, and the animal can still effectively stimulate the animal's feed intake and improve the digestion and absorption rate after eating.

Description

technical field [0001] The application relates to the field of microbial fermentation, more specifically, it relates to a fermentation process of bacterial enzyme feed. Background technique [0002] Bacterial enzyme feed uses microorganisms and compound enzymes as biological feed starter strains to convert feed materials into microbial bacterial protein, biologically active small peptide amino acids, microbial active probiotics, and compound enzyme preparations. [0003] The feed is homogeneous and fluffy after fermentation, which improves the palatability of the feed and stimulates the feed intake of animals; and the complex macromolecular organic substances such as cellulose, starch, and protein in the feed are degraded to a certain extent into animals that are easy to digest and absorb. Monosaccharides, disaccharides, oligosaccharides and amino acids and other small molecular substances, thereby improving the digestion and absorption rate of the feed; at the same time, a ...

Problems solved by technology

[0004] Generally, fermented feed needs to be stored in a low-temperature and dry environment. When the storage temperature is higher than 15°C, the unstable nutrients in the feed begin to lose their activity, especially in high-temperature environments in summer, where the average temperature is above 20°C. The loss of nutrients can reach 10% or more, so the feed needs to be placed in a low-temperature and dry environment before feeding animals; The way of feeding, the feed cannot be eaten all at once. In the summer climate, due to the high ambient temperature, the nutrients in the remaining feed tend to lose their activity in a high temperature environment, which easily affects the feed intake and digestion of animals. Absorption rate
