摘　　要：流产是怀孕奶牛的常发性疾病,其造成奶牛产犊间隔延长,严重影响牧场的盈利能力。流产的主要原因包括非感染性因素及感染性因素,但实际生产中,引发流产的真实原因错综复杂。一般情况下,奶牛年流产发生率控制在2%~5%是较合理范围。笔者所述流产事件牛场,当年奶牛流产率达到20%,经全方位分析检测确认,病毒性腹泻、传染性鼻气管炎、新孢子虫合并感染以及糖皮质激素混于中药中误用均为流产发生病因。可见,牧场建立高效合理的疫病监控保健体系以及谨慎使用中成药均为保证牛群健康的重要环节。Abortion is a frequent disease for pregnant cattle and the calving interval of dairy cattle is prolonged,which seriously affects the profitability of the farm.There are infective and non-infective causes to abortion which are actually complex in real production.As usual,the abortion rate is controlled within a reasonable range of 2%-5%.The abortion rate of the in-case pasture the author is referring to amounted to 20%at the time.The coinfection of BVDV,IBRV and Neospora,the misuse of glucocorticoid mixed in TCM combinedly caused the disease after all-angle analysis.Obviously,establishing efficient and reasonable pandemic surveillance health system and careful usage of Chinese patent medicine on pasture are significant sections of herd health ensurance.
