Fermented soybean meal and preparation method thereof

Abstract

The invention provides fermented soybean meal and a preparation method thereof. The preparation method comprises steps as follows: step S10, forage traditional Chinese medicine plants are pulverized, and forage traditional Chinese medicine plant powder is obtained; step S20, the forage traditional Chinese medicine plant powder, soybean meal, sugary substances and water are mixed in a preset mass ratio, and a soybean meal mixture is obtained; step S30, the soybean meal mixture is fermented, and the fermented soybean meal is obtained. The fermented soybean meal is digested and absorbed by animals more easily when taken as animal feed or an animal feed additive. The fermented soybean meal contains multiple forage traditional Chinese medicine plant ingredients capable of improving the intestinal environment and metabolites of multiple probiotics, the occurrence probability of piglet diarrhea can be reduced remarkably after a feeding object is fed with the fermented soybean meal, and besides, the fermented soybean meal has the advantages of no toxic or side effects, no pollution and no harmful substance residues, particularly, the feeding object does not generate drug resistance, and the fermented soybean meal meets the development tendency of antibiotic inhibition in feed.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a fermented soybean meal and a preparation method thereof. Background technique [0002] At present, soybean meal is a by-product obtained after soybean oil is extracted, and it is a kind of high protein. Soybean meal is the main raw material for making livestock and poultry feed and is widely used in the poultry and aquaculture industries. Bio-fermentation of soybean meal can remove the anti-nutritional factors in soybean meal, and the fermented soybean meal contains a large number of probiotic components with high biological activity, which can improve the microbial balance in the intestinal tract of animals and supplement a large number of active probiotics in the intestinal tract , Inhibit the growth of Escherichia coli, Salmonella and other harmful bacteria, improve the immunity of livestock and poultry, and reduce the occurrence of diseases. [0003] Accor...

AI Technical Summary

Problems solved by technology

[0004] At present, antibiotics are still mainly used in the prevention of swine diarrhea at home and abroad, but due to long-term and large-scale administration of antibiotics, the generation of bacterial resistance in pigs and drug residues in pigs and antibiotic residues in pork have caused a series of problems such as food safety. problems, endangering human health
