摘要
繁殖是肉牛生产的关键环节,母牛不孕是肉牛业发展的瓶颈问题之一,由于设施养殖水平不高等原因,母牛不孕性疾病发病率高、产犊量低,造成母牛淘汰率高,经济效益低,从源头上探讨设施养殖肉牛母牛的不孕原因,对提高母牛繁殖率和经济效益有重要意义。
Although breeding is a key link in the beef cattle production, cow infertility is one of the problems for its development. Because of low facilities and raising conditions,infertility disease inci- dence is high and the rate of calving is low, which leads to high mortality of cows and lower economic ben efit. ving This paper will discuss the basic reasons why the cows are infertile, which plays a great role in impro cow＇s fertility and economic benefits.
