摘　　要：甘肃省白银市平川区自2022年鼓励农户发展肉牛养殖,养殖规模逐渐扩大,存栏量逐步上升,但是母牛饲养都较为分散,种公牛数量少,为方便实施品种改良,平川区畜牧中心向农户推广同期发情技术及配种技术。在2022年,通过同期发情技术完成配种任务1563头,累计产犊1040头,受胎率达到66.5%以上,相较于自然交配增长12.3个百分点。Since 2022,Pingchuan District of Baiyin City has encouraged farmers to develop beef cattle breeding.The scale of breeding has gradually expanded,and the number of cattle on hand has gradually increased.However,cow breeding is relatively scattered,and the number of breeding bulls is small.In order to facilitate the implementation of variety improvement,the district animal husbandry center has promoted estrus synchronization technology and breeding technology to farmers.In 2022,1563 mating tasks were completed through synchronous estrus technology,resulting in a total of 1040 calves.The conception rate reached over 66.5%,an increase of 12.3 percentage points compared to natural mating.
