Fermentation technology of bacterial enzyme feed

Abstract

The invention relates to the field of microbial fermentation, and particularly discloses a fermentation technology of bacterial enzyme feed. The fermentation technology comprises the following steps of: S1, preparing a yeast block, dissolving the yeast block to prepare a feed seed solution, wherein the yeast block is prepared from a yeast block material and mixed bacterial powder, and the mixed bacterial powder is prepared from saccharomycetes bacterial powder and bacillus subtilis bacterial powder; and S2, stirring and fermenting the feed seed solution prepared in the step S1 at 28-38 DEG C for 68-78h, and then stirring and drying at 47-58 DEG C for 32-40h to prepare the finished product bacterial enzyme feed. The bacterial enzyme feed has good storage stability in a high-temperature environment, even if animals cannot eat up the bacterial enzyme feed at a time, the remaining bacterial enzyme feed is exposed to the high-temperature environment, nutrient substances in the remaining bacterial enzyme feed still have good biological activity. after animals eat the feed, the feed intake of the animals can still be effectively stimulated, and a digestion and absorption rate is improved.

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 ...

AI Technical Summary

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
