Abstract

The invention provides a composite microbial starter, a biologically fermented feed prepared by using the starter, and a preparation method of the feed. Aspergillus niger, yeast and Bacillus subtilisin the composite microbial starter have synergistic effects according to a specific ratio, and enhance the fermentation effect. Fresh citrus residues, rice bran, wheat bran, stone flour and magnesiumsulfate in the biologically fermented feed have a reasonable formula. The biologically fermented feed can provide natural pigments, organic mineral elements, dietary fibers, probiotics and metabolitesthereof, needed by production of high-quality livestock and poultry meat, and has broad application prospects and great market values.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a composite microbial starter, a biologically fermented feed prepared by using the starter and a preparation method thereof. Background technique [0002] my country is rich in citrus. In addition to being eaten directly, a large part of citrus is used for fruit juice processing, which produces a large amount of citrus peels. Landfilling and other methods occupy a lot of land, the effect is poor, pollute air, soil and water, etc., seriously affecting people's production , life and health. At present, the more effective method is to dry the pomace as feed, but citrus pomace is rich in pectin and has a high content of bound water. Drying pomace consumes a lot of energy and costs, making it difficult for industrial production. In addition, the protein content of citrus pomace is extremely high. Low nutritional value of feedstuffs. At present, there are studies to deg...
