摘　　要：瘤胃酸中毒是奶牛临床上常见的消化紊乱性疾病,主要分为急性和亚急性两种类型。发病主要是由于奶牛摄食了大量的碳水化合物饲料在瘤胃内发酵,产生过多有机酸,导致瘤胃内p H出现非生理性下降,同时伴有有毒物质产生,最终引发瘤胃内微生物菌群失调、瘤胃内消化机能紊乱、代谢异常等问题。本文主要综述急性与亚急性瘤胃酸中毒的主要发病机制、集约化饲养模式下的诊断方法、营养调控措施,以期为奶牛瘤胃酸中毒的防治提供依据。Ruminal acidosis is a clinically common digestive disorder of dairy cows,mainly divided into two types,that is, acute and subacute.The disease is mainly due to the dairy cows fed with a large amount of carbohydrate which is ferment- ed in rumen,producing too much organic acids.It makes the pH non-physiologically decline in the rumen,with toxic sub- stances produced at the same time,which will eventually cause problems ,such as rumen biological dysbacteriosis and gas- trointestinal dysfunction of the rumen,and digestive metabolic abnormalities and so on.This article mainly reviewed the main pathogenesis of acute and subacute ruminal acidosis,intensives the diagnostic methods in breeding mode and the regulating measures of nutrition,that was in order to provide basis for the prevention and treatment of ruminal acidosis for dairy cows.
