摘　　要：近20年来,我国奶牛集约化饲养的规模在大中城市近郊地区迅速扩大,其皱胃变位的发病率也有明显增加。调查发现,平均有3.3%的奶牛会发生皱胃变位,产前3周到产后4周的围产期是发生此病的危险期。其中有85%表现为左方变位(left displace,LD),15%表现右方变位(right displace,RD)。文章从皱胃弛缓、机械性因素、胃壁损伤、某些营养物质缺乏、有毒物质慢性中毒、遗传因素及饲养管理等方面阐述了皱胃变位的可能发病原因及可能的发病机理,从而对该病的实验室检验指标进行描述和分析,以便建立系统的诊断思路。Along with the expansion of the intensive-feeding for the milk cow and the increace of the milkproducing, the outbreak rate of this disease has a trend of increasing gradually. In recent 20 years, the intensive-feeding expands quickly in nearby regions of big cities in our country, the outbreak rate of the displaced abomasum also increases obviously. Accoding to the investigation, there is 3.3% milk cow equally affected by this disease ,and the period of prenatal 3 weeks and postnatal 4 weeks is the dangerous period that affected by this disease. Among them 85% is LDA,15% is RDA. The factor and mechanism were explained by several factors, namely abomasums atony, machine agent, stomach wall in jury, the absence of some of nutrient substances poisonous substance lead to chronic into xication, genetic factor,feeding management and so on. Describing and analysising clinical symptom and date of lab test systematic diagnosis pathways and routine were established.
