生态制剂是具有活性的新型饲料添加剂,目前在我国饲料行业内正处于开发和实验的过程中,因此,在畜牧生产中进行饲料调制时,不能与其他饲料添加剂随意混合使用,而必须对新研发的微生态制剂的菌种进行比较完整的毒理学试验和相应的安全测试,确定对养殖畜禽没有毒副作用后才可以在畜牧生产中进行推广应用。微生态制剂在肉羊养殖中应用时,既可以改善羊只瘤胃的发酵环境,恢复消化道优势菌群及机体内微生物的平衡,提高饲料的消化和利用效率,提升肉羊的生产性能和产品质量;又能减少蛋白质向氨和胺的转化,降低粪便恶臭,改善环境卫生;还能刺激羊只肠道内的免疫功能,及时杀死入侵病菌,增强羊只对疾病的免疫能力。因此微生态制剂的适量适时利用,在肉羊养殖中有着显著的社会效益和经济效益。

Probiotic is a new bioactive feed additive, which is being developed in feed industry in China. It couldn't be mixed with other additives during feed processing. It also couldn 't be popularized and used in the livestock production unless it shows no toxic and side effect by safety and toxicology tests in the new species or strains. In the sheep production, probiotic not only improve fermentation environment of sheep rumen, restoration of gastrointestinal micro flora and balance of the microbial populations, nutrients digestibility, productive performances and quality of the products, but also reduce the transforming protein to ammonia and amines, fecal odor for improving environmental health. Moreover, probiotic could stimulates immune function of sheep gut and enhance the their immunity to the disease. Therefore, appropriate application of probiotic could bring remarkable social and economic benefits in sheep breeding.
