摘　　要：瘤胃酸中毒是反刍动物集约化养殖模式下常见的一类营养代谢病,其影响动物的生产性能,严重时甚至导致动物死亡,从而对牧场造成巨大经济损失。乳酸利用菌作为具有分解乳酸功能的一类内源性瘤胃菌群,是缓解反刍动物瘤胃酸中毒的重要菌群,对反刍动物生产有重要意义。本文主要综述了乳酸利用菌的特征、分解能力及其对酸中毒的调节和影响因素,以期为缓解瘤胃酸中毒提供新的理论指导和实践参考。Ruminal acidosis is a common metabolic disease in ruminant intensive farming mode,which affects animal production performance,and even leads to animal death in severe cases,thus causing great economic losses to farms.Lactateutilizing bacteria,as endogenous rumen microorganisms with the ability to degrade lactate,play a crucial role in alleviating rumen acidosis in ruminants,making them highly significant for ruminant production..Therefore,this paper mainly reviews the characteristics of lactic-utilizing bacteria,their decomposition ability,and their influencing factors,with a view to providing new theoretical guidance and practical references for the alleviation of rumen acidosis.
