芽孢杆菌在畜牧生产应用中的研究进展

The Research Progress on Application of Bacillus in Animal Production

芽孢杆菌作为一类活菌制剂具有调控消化道菌群平衡、提高机体免疫力、改善动物生产性能等作用，同时还具有抗逆性强、耐高温、耐高压、易贮存等独特的生物学特性，因此，其研究前景广阔。本文从芽孢杆菌的生物学特性、种类、作用机理、应用效果及影响因素等方面进行综述。

As a kind of living bacterium bacillus preparation, Bacillus have been used in ani- mal nutritional physiology to regulate flora balance of animal gastrointestinal, improve immunity and animal production performance, which possess unique biological characteristics such as resist- ance to stresses, high temperature and high pressure, and easier to store. Therefore, the research on this bacterium has broad prospects. The biological characteristics, species, functioning mecha- nisms, outcomes of Bacillus and impact factors of their applications were reviewed.
