Microbial fermentation feed and preparation method and application thereof

Abstract

The invention discloses microbial fermentation feed. The microbial fermentation feed is prepared from, by weight, 3-5 parts of a complex microbial agent, 680-730 parts of a fermentation raw material,275-325 parts of an energy raw material, 350-400 parts of water and 1-2 parts of brown sugar by mixed fermentation. The complex microbial agent is made by mixing of 5-6 of bacillus subtilis, enterococcus faecalis, plant lactobacillus, bacillus pumilus, clostridium butyricum, bacillus megaterium, bacillus amyloliquefaciens or lactobacillus casei. By fermentation treatment of the fermentation raw material and the energy raw material with the complex fermentation strain, enzymolysis of coarse fibers in the fermentation raw material is realized, organic nitrogen and inorganic nitrogen, which can be hardly used by animals, in the fermentation raw material are converted into bacterial protein, and macromolecular carbohydrates, which cannot be absorbed by the animal, in the energy raw material are converted into absorbable low-molecule carbohydrates.

Description

technical field [0001] The invention belongs to the field of feed, in particular to a fermented feed, in particular to a microbial fermented feed and its preparation method and application. Background technique [0002] my country is a large agricultural country. For a long time, the development of animal husbandry mainly relies on grain and forage. This has become a deep-rooted traditional understanding of farmers. The contradiction between food and grain has become increasingly acute and difficult to coordinate. However, only about 20% of the more than 600 million tons of crop stalks produced in my country every year are used as feed for grass-eating livestock, and most of the rest are used as energy fuels or burned in vain. Since the 1950s, my country has begun to apply silage and ammonia treatment technology, using crop straw as feed for cattle, sheep and other large livestock, increasing the utilization rate of straw. In the vast rural areas, in addition to vigorously ...

Problems solved by technology

[0005] At present, the application of biologically fermented feed is not ideal, and the application effect is not good. The feed palatability is higher, the nutrients are richer and easier to absorb, which has important application significance
