The invention discloses a method for preparing feed by using microorganisms, which includes: preparing a microbial starter; culturing the microbial starter with a culture medium; parts, 40-50 parts of rice bran, 5-10 parts of bone meal, and 0.1-0.2 parts of brown sugar; add water and brown sugar, and after the brown sugar is completely dissolved, add the microbial culture medium; carry out fermentation, the fermentation time is 25-30 days, during the fermentation process, During the first 2 days of fermentation, control the fermentation temperature at 28°C, within 3 to 20 days of fermentation, control the fermentation temperature at 38°C, and control the fermentation temperature to decrease at a rate of 0.1‑0.2°C/day during the rest of the fermentation period ;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. |
