The invention belongs to the technical field of feed production, in particular to a method for improving the quality of bacterial chaff feed by mixing and fermenting multiple bacterial species, comprising the following steps: S1: preparing a culture medium; S2: improving the activity of the culture medium; S3: sterilizing the culture medium; S4 : expansion of microbial strains; S5: mixed fermentation of multiple strains; S6: stable mixing; S7: drying and crushing; S8: preservation. The present invention provides sufficient nutrients to the medium through S2 to improve the activity of the medium so as to facilitate the full docking with multi-strain mixed fermentation, and by adding the inhibitory mold and decomposing mold added in S5, the inhibition of growth by inhibiting the mold is more efficient. The fast growth of strains prevents them from over-absorbing nutrients, and uses decomposing molds to decompose the excrement of the faster-growing strains to provide certain nutrients to the slower-producing strains, which ensures that the mixed fermentation of multiple strains is carried out. During the process, the various strains do not affect each other and grow together, and there will be no large-scale death of the strains. |
