Study on the development of microbial compound bacteria and its application in the microbial fermentation bed of goose house

With the continuous expansion of the scale of livestock and poultry breeding, people's awareness of environmental protection is gradually strengthened, and it is imminent to improve the pollution status of soil, water and air caused by livestock and poultry manure. Microbial fermentation bed technology is widely used in cows, pigs and other large animals because of its green environment and ecological breeding, and has achieved remarkable results. However, the application of fermentation bed technology in meat goose breeding is still in the exploratory stage in China, and there are few researches on the microecological mechanism of fermentation bed culture process.
