[0064] In a preferred version, the preparation method of the microbial inoculum comprises the following steps:
[0065] 1) After weighing the Bacillus licheniformis, Enterococcus faecalis and Bacillus coagulans according to their composition, they are inoculated into liquid culture medium with 10-20 times volume, and anaerobically fermented until the bacteria content is 2×10 8 -5×10 8 cfu / mL, stop fermentation to obtain mixed bacterial solution 1;
[0066] 2) After weighing the Bacillus megaterium and Bacillus subtilis according to their composition, inoculate them into a liquid culture medium with a volume of 10-20 times, and ferment aerobically until the bacteria content is 2×10 8 -5×10 8 cfu / mL, stop the fermentation to obtain the mixed bacterial liquid II;
[0067] 3) Mix the mixed bacterial solution 1 obtained from 1) and the mixed bacterial solution 2 obtained from 2) in a volume ratio of 1-3:5-10 to obtain the microbial bacterial solution;
[0068] Wherein, the liqu...
Embodiment 1
[0071] Select a beef cattle farm in Yangyuan County, Zhangjiakou City, Hebei Province, from May 3, 2018 to August 2, for a period of three months. Randomly select 300 beef cattle from each beef cattle of the same age as the test group, and randomly divide them into three groups A, B and C, and randomly select 100 beef cattle from the remaining beef cattle as the control group. Breeding in separate houses, the basic feeding and environmental conditions are the same. In the control group, the cow bed was laid with sand and sawdust according to the original feeding and management method, and the manure in the cow house was cleaned regularly every day. Group A is managed according to the original feeding and management method, and the microbial bacterial liquid is directly sprayed once every 5 days in the cattle bed; Group B is managed according to the original feeding and management method, and the first straw mat and the second straw mat are directly laid according to this appli...
