微生物制剂对畜禽圈舍环境的改善研究进展OA北大核心CSTPCD

The harmful gases produced in the process of large-scale livestock and poultry breeding will reduce the air quality of the enclosure and affect the health and growth of livestock and poultry.Microbial agents can promote the digestion and absorption of nutrients in feed,maintain the microecological balance of the digestive tract,reduce the generation and emission of harmful gases,and improve the environment of livestock and poultry houses.In this paper,the effect of harmful gases in livestock and poultry houses on livestock and poultry,the mechanism of microbial preparations to reduce harmful gas in livestock and poultry houses,the research and application of microbial preparations to improve the environment of livestock and poultry houses,and the influencing were reviewed,in order to provide reference for the development of green breeding industry.
