中文摘要：

枯草芽孢杆菌作为一种绿色健康的微生态制剂,具有调节动物肠道平衡、促进营养吸收、提高免疫能力等功能。微生态制剂是抗生素的理想替代品之一,因其可有效防治动物疾病,并且无毒副作用,无残留污染,不产生抗药性,还能促进动物生长发育而在禽畜养殖中广泛应用。通过综述枯草芽孢杆菌的特性、作用机理以及枯草芽孢杆菌微生态制剂在禽畜养殖中的效果,分析了目前微生态制剂存在的问题及解决措施,并展望了其未来发展方向,为后续禽畜养殖提供借鉴和参考。

英文摘要：

As a kind of green and healthy microecologics,Bacillus subtilis could balance the intestinal flora,promote the nutrient absorption and enhance immunity.Microecologics is one of the ideal antibiotics alternative,which are effective in preventing and treating animal disease and promoting the growth and development of the animal.Because of its advantages,such as no toxin side effect and no residual or drug-resistant,microecologics has been used in livestock breeding widely.Here,we concluded the characteristics and mechanism of Bacillus subtilis,elaborated application of microecologics on livestock breeding,discussed its problems and suggested its solved methods.In the end,the future of microecologics was expected in order to provide a reference for subsequent livestock breeding.
