摘要：

The invention relates to a method for producing a high-energy high-protein feed by fermenting and decomposing polysaccharide in corn steep liquor, which comprises the following steps of: respectively carrying out amplification culture on bacillus subtilis, bacillus licheniformis, yeasts and aspergillus oryzae and then adding the obtained product into a seeding tank to cultivate for 60-72 hours toobtain a composite bacterial liquid; mixing and heating the corn steep liquor and water, then adding xylanase, glucanase, protease and fatty acid enzyme into a mixed solution and carrying out heat preservation and fermentation on the mixed solution; adding ammonium sulfate, urea, monopotassium phosphate, magnesium sulfate and caramel into the fermented mixed solution; after uniformly mixing, regulating the pH value into the range of 5.5-6.5; then adding the composite bacterial liquid into the mixed solution, stirring the mixture, filling oxygen into the mixture and fermenting the mixture; andafter the mixture is fermented well, spraying the mixture on bran or bean pulp, drying after uniformly stirring, grinding the dried mixture into powder with granularity of less than 2mm, and packaging to obtain the high-protein feed. In the method, the polysaccharide can be sufficiently decomposed. The method has high speed and high efficiency on the aspect of transformation. After being decomposed, a product contains various beneficial microorganism viable bacteria, digestive enzymes, metabolites and small molecule substances which can be sufficiently adsorbed by animals.
