Feeding microecologic preparation based on beer grains and rice bran meal

Abstract

The invention relates to a feeding microecologic preparation which has high efficiency, is very low in cost, and is formed by performing three stages of probiotics fermentation to beer grains and rice bran meal, and is also called microbial forage additive. The feeding microecologic preparation is characterized in that after beer grains and rice bran meal are subjected to the first stage of fermentation preprocessing through neurospora, lignin, cellulose and the like are sufficiently degraded; part of rice bran meal and a small amount of soya bean meal are added to be subjected to the second stage of fermentation through bacillus and microzyme; and nutrient substances generated when waste is degraded by mould and nutrient substances generated when mould is dismembered are absorbed; and then part of rice bran meal and a small amount of soya bean meal are added to be finally subjected to the third stage of anaerobic fermentation through lactobacillus, bifidobacterium and the like in a one way membrane anaerobic bag, so that finished products are obtained. The feeding microecologic preparation has the advantages that solid material is not required to be subjected to high temperature sterilization, the finished products are not required to be subjected to drying process, the quality guarantee period is more than one year, the amount of additive reaches 5 to 30 percent, the amount of active probiotics is high, the amount of enzyme is abundant, the amount of bacterials is very little, the feeding effect is obvious, and the feeding microecologic preparation has obvious ecological and social benefits.

Description

technical field [0001] The invention belongs to the field of microecological preparations for feeding, in particular to a novel microbial feed additive with high efficiency and low cost based on fibrous brewing waste. Background technique [0002] China is already the world's largest beer country, with an annual output of more than 10 million tons of beer's grains, which are rich in protein (25-35%), cellulose (14-25%), lipids (6-10%), vitamins and other nutrients, but its high moisture content makes it difficult to store, and once unsalable, it is easy to rot and rot and affect the environment. At present, some domestic beer production enterprises directly dry the brewer's grains and sell them as feed, which not only consumes a lot of energy, but also the non-protein nitrogen and inorganic nitrogen in this feed cannot be effectively used by animals, and the cellulose also hinders the absorption of nutrients. . Therefore, the reasonable development and utilization of brewe...

Problems solved by technology

Therefore, after rice bran is properly treated, the feeding effect may be better. The published patent CN102334611A is inserted into Bacillus natto and yeast, and the disclosed patent CN102356815A is inserted into enzyme bacteria, Bacillus subtilis, yeast and Lactobacillus. The lignocellulose degradation ability of the latter is limited, and the latter is fermented by aerobic bacteria and anaerobic bacteria in one step, and the effect is not good

These fermented products have to be dried, which consumes a lot of energy, and the preservation rate of probiotic bacteria and enzymes is low, and the feeding effect is not good, which is not conducive to the promotion of industrialization
