摘要： 随着奶牛行业发展,牧场走规模化、集约化道路,追求高产量同时,都关注奶牛产后是否能尽快配种并受孕,从而缩短产犊间隔,减少饲养成本。新产牛护理中子宫保健是指奶牛产后子宫恢复到未孕时形态和功能的生理过程。产后子宫保健的过程和子宫恢复的状态决定奶牛产后第1次发情的受胎率,即首配受胎率。奶牛产后如果子宫复旧不全,会多发繁殖疾病,严重影响奶牛首配受胎率。由于产后发情配种未怀孕则导致受孕时间推迟,产犊间隔增加,意味着空怀饲养天数增加和牧场经济效益降低,所以牧场应时刻关注奶牛产后子宫护理工作及常见繁殖疾病的防控。

Abstract: With the development of dairy industry,the pasture takes the road of scale and intensification,and pursues high yield. At the same time,everyone pays attention to whether it can be bred and conceived as soon as possible after delivery,thus shortening the calving interval and reducing the feeding cost. Nursing care of newborn cows is a physiological process in which the postpartum uterus of dairy cows returns to the shape and function before pregnancy. The process of postpartum uterine health care and the state of uterine recovery determine the pregnancy rate of the first estrus after delivery,that is,the first mating pregnancy rate. If the uterus of dairy cows is incomplete after delivery,it will cause multiple reproductive diseases,which will seriously affect the first-mating pregnancy rate of dairy cows. Postpartum estrus mating without pregnancy will delay the conception time and increase the calving interval,which means that the number of days of empty feeding will increase and the economic benefits of pasture will decrease. Therefore,pasture should always pay attention to postpartum uterine care and the prevention and control of common reproductive diseases.
