有效微生物菌群技术在畜禽生产中的应用研究进展

Recent advances in application of effective microorganisms in animal production

有效微生物菌群(Effective microorganisms,EM)是一类由光合菌、酵母菌、固氮菌、放线菌、乳酸菌等多种微生物组成的微生物群。它是通过微生物之间协同共生关系而形成的一个复杂而稳定的微生态系统,在发酵饲料、畜禽养殖、水产动物养殖、作物生产、环境治理、生物肥等方面得到广泛应用。通过分析有效微生物菌群在农副产品发酵、畜禽生产及畜禽舍内环境中的作用,为其在畜牧生产中的应用提供参考。

Effective microorganisms(EM)is a kind of microflora composed of photosynthetic bacteria,yeast,nitrogen-fixing bacteria,Actinomycetes,Lactobacillus and other microorganisms.It is a complex and stable microecosystem formed by the symbiotic and proliferative relationship between microorganisms,and is widely used in fermented feed,livestock and poultry breeding,aquaculture,crop production,environmental governance and biological fertilizers.This review is mainly to summarize the role of EM in the fermentation of agricultural byproducts,livestock and poultry production and the environment of livestock and poultry house,to provide a reference for the application of EM in animal production.
