摘　　要：为了确定补饲高蛋白饲料对产后母牛繁殖性能的效果,选择30头西门塔尔产后母牛在产后90 d内持续补饲高蛋白饲料。利用直肠检查及B超监测技术在母牛产后15 d、30 d、45 d、60 d、90 d时对子宫恢复情况及卵巢状态变化进行检查,并及时记录胎衣、恶露以及发情配种情况。结果表明,产后母牛补饲高蛋白饲料300 g/d,繁殖性能发生了明显的改善。To identify the effects of supplementary high protein feed on the reproductive performance of Simmental postpartum cow, 30 Simmental postpartum cows were selected out to be constantly fed by supplementary high protein feed within 90 days after their delivery. The recovery status of their uteruses and changes of their ovaries were examined by means of rectal palpation and B-ultrasonic monitoring technology respectively at days 15, 30, 45, 60 and 90 after their delivery,and the conditions of afterbirth, lochia and estrus breeding were recorded timely.It is showed that the reproductive performance of postpartum cow is obviously improved when cow is fed by supplementary high protein feed as 300g/day.
