摘　　要：奶牛繁殖障碍是使奶牛繁殖力降低的主要原因,了解奶牛繁殖障碍的致病机理,可以提前做好奶牛繁殖障碍性疾病的预防,对于奶牛繁殖率的提高具有重要意义。该文从奶牛先天性繁殖障碍、后天获得性繁殖障碍、传染感染性因素、营养因素、自身免疫因素、环境应激性因素、繁殖技术不当、生殖器官疾病类等方面加以分析,为养殖者提供了更多的理论依据,利于养殖者对症预防,以指导生产。The reproductive disorder of dairy cows is the main reason for the decrease of the fecundity of dairy cows.Understanding the pathogenic mechanism of the reproductive disorder of dairy cows can prevent the reproductive disorder of dairy cows in advance,which is of great significance for the improvement of the reproductive rate of dairy cows.From cows congenital reproductive barriers,acquired sexual reproduction barrier,contagious infectious factors,nutritional factors,autoimmune,environmental stress factors,improper breeding technology,the respect such as reproductive organs disease class analysis,provide more theoretical basis for farmers,farmers suit the prevention,to guide production.
