牛的流产是生殖浪费的一个重要原因，并且具有经济重要性，因为奶牛群中的单次流产事件估计花费630磅。有些流产是由于传染病，其中有几种是人畜共患疾病。任何畜群都会发生零星流产，但一旦发生率超过3%，或连续发生几次流产，就必须进行进一步调查，以确定原因，从而采取控制措施。本文回顾了牛流产的常见原因，并概述了流产爆发的调查方法，描述了可用于诊断的测试。
ABORTION in cattle is a significant cause of reproductive wastage and is of economic importance as a single abortion event in a dairy herd is estimated to cost 630 pound. Some abortions are due to infectious diseases, several of which are zoonotic. Sporadic abortions occur in any herd, but once the incidence exceeds 3 per cent, or several abortions occur in close succession, further investigations must be carried out to try to determine the cause so that control measures can be instigated. This article reviews the common causes of abortion in cattle and outlines an approach to the investigation of an abortion outbreak, describing the tests available for diagnosis.
