The invention discloses a preparation method of microbial fermentation feed, comprising: step 1, preparing a microbial starter, including the following microorganisms in parts by mass: 10-20 parts of yeast, 10-20 parts of Bacillus subtilis, 5 parts of lactic acid bacteria -8 parts, 5-8 parts of Aspergillus niger; step 2, using culture medium to cultivate microbial starter; step 3, preparing fermented product, the fermented product includes the following substances in parts by mass: 40-50 parts of soybean meal, 40-50 portions of rice bran, 5-10 portions of bone meal, and 0.1-0.2 portion of brown sugar; step 4, adding water and brown sugar, after the brown sugar is completely dissolved, add the microbial culture liquid; ferment, and the fermentation time is 25-30 days; step 5, drying. The microbial fermentation feed prepared by the invention contains fermented metabolites that are beneficial to livestock, helps the reproduction of beneficial microorganisms in the intestinal tract of the livestock and the health of the intestinal tract, and improves the growth of the livestock. |
