山东省泰安市某奶牛场从国外大规模引进妊娠母牛,分娩后奶牛配种受胎率低,直接影响奶牛场的生产能力和经济效益。通过现场座谈、实地查看和直肠检查等方式发现,造成受胎率低的原因是妊娠母牛长期营养不足,分娩后长期不发情、子宫疾病所致。根据该场实际情况,本文从加强产后营养、疾病治疗、减少外界环境气候（季节）的影响、加强环境及牛体消毒工作、做到“适时输精”等方面阐述了如何能够更好地促进奶牛产后机能恢复,提高奶牛受胎率,为奶牛的日常管理工作提供经验,供从业人员参考。
The pregnant cows in a farm in Tai’an city of Shandong province were imported from abroad on a large scale. After parturition,occurrence of low conception directly affects the production performance and economic benefits of the farm.The results of the on-site panel discussion,investigation and rectal examination showed the low rate of conception is mainly due to the long-time lack of nutrition,long-term postpartum anestrus and uterine diseases. Based on the real conditions of the farm,this paper aims to provide countermeasures to enhance postpartum recovery ability from different perspectives,including nutrition and disease treatment,external climate（season）impacts,environment disinfection and artificial insemination.This research would provide cow practitioners with practical experience for daily management.
