Strain composition for feed fermentation and feed prepared from composition

Abstract

The invention discloses a strain composition for feed fermentation. The composition is prepared from the following strains in parts by weight: 12 to 18 parts of lactic acid bacteria, 15 to 25 parts of saccharomycetes, 3 to 8 parts of mould, 12 to 18 parts of bacillus, 8 to 12 parts of streptococcus, 4 to 6 parts of photosynthetic bacteria, 8 to 12 parts of bacteroides and 8 to 12 parts of trichoderma. The invention also provides a feed prepared from the fermentation strain composition. The strain composition has the advantages that nutritional ingredients in feed can be well converted into biological protein which can be easily absorbed by pigs, harmful strains and mosquitoes and flies can be inhibited from being generated, no antibiotic needs to be added, the disease resistance and disease prevention capacity of the pigs can be improved, and the meat quality of pork can be improved.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a strain composition for feed fermentation. Background technique [0002] In traditional feed production, because traditional corn, soybean meal, bran and other grains do not have the effect of disease prevention and disease resistance, people often add antibiotics to feed to reduce the time of pigs' disease. However, long-term use of antibiotics will cause a series of health problems when humans eat these pork in the later period. In order to solve the problems such as the enrichment of antibiotics caused by adding antibiotics in feed, people began to use microbial fermentation technology and the composition of strains to replace the application of antibiotics. [0003] For example, the Chinese invention patent application publication with the publication number CN102326667A discloses a method for preparing fermented feed for livestock and poultry without antibio...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned feed prepared by microbial fermentation solves the problems caused by the use of antibiotics in the feed to a certain extent, but it can be seen from the above literature that the proportion of nutrients used in it is very large. The digestive function is very poor, and its absorption and utilization rate of food is very low. On the one hand, it causes a huge waste of food. On the other hand, due to the incomplete digestion of too much organic matter in the intestine, the excreted feces are very smelly, and it is also very easy to breed bacteria. and mosquitoes have brought very adverse effects on the ecological environment

At the same time, the fermentation of the above-mentioned microorganisms is based on a large amount of nutrients. When the ratio of nutrients is too low, its efficacy is unknown, which also brings certain limitations to the application.
