The invention discloses feed composite multi-microfunctional microbial inoculums. The feed composite multi-microfunctional microbial inoculums are obtained by mixing
lactic acid bacterium mixed bacterial liquid,
saccharomycetes mixed bacterial liquid, bacillus mixed bacterial liquid and a
thallus protective agent, wherein the
mass ratio of the components is 5:2:1:2. Application of the feed composite multi-microfunctional microbial inoculums in the field of feed is that the feed composite multi-microfunctional microbial inoculums are applied to the conventional feed according to 10 kg per
ton of feed. The used bacterial strains are probiotics which are allowed to use through audit of the Department of
Agriculture, and can exert special effect in the intestinal track of a pig through long-time production practice; and the probiotics can completely exert the effect through
commensalism, breeding, competition or
phagocytosis, have high propagation speed of the
thallus, have strong competitive
advantage, can perform industrialized large-scale production, have
high survival rate and high stability after use, and can promote the growth and development of the pigs, prevent diseases, inhibit release of harmful gas and reduce mosquitoes and flies in a colony house.
