Abstract: Rumen acidosis is a severe digestive system disorder which causes a great harm to the health and production performance of food-producing animals.After entering the rumen,probiotics can stabilize the ruminal pH value by maintaining the balance of the microbial community in the rumen.In addition,probiotics can bring its immune function back to normal by stimulating the body,and alleviate the symptoms caused by acidosis.The current state-of-the-art of knowledge about gastric acidosis is reviewed in this paper.

Key words: rumen acidosis; probiotics; microflora

摘要： 瘤胃酸中毒是一种严重的消化系统紊乱,对动物的健康及生产性能危害极大,益生菌进入瘤胃后可以通过稳定瘤胃内微生物群落的平衡,进而维持瘤胃液pH值的稳定,达到缓解瘤胃酸中毒的作用。此外,益生菌还通过刺激机体,恢复其正常的免疫机能,缓解由于酸中毒带来的症状。本文就目前的研究进展进行了综述。
