摘　　要：子宫复旧是奶牛产后生殖器官恢复的一个重要时期,复旧时间的长短会直接影响产后第一次发情的时间,子宫复旧的正常时间为产后30～46d。本试验为研究促卵泡素(FSH)与促黄体素(LH)在子宫复旧过程中的变化规律,选择了年龄、胎次相近,健康状况良好的产后奶牛15头,应用放射免疫分析法在子宫复旧期间每3天对奶牛血清中FSH与LH进行一次测定,前后持续10次。由试验数据可得出,FSH与LH分泌水平在子宫复旧的早期比较低,FSH浓度到产后第15天达到峰值,LH从产后第21天开始大幅上升,到产后第24天浓度达到峰值,之后二者浓度变动范围不大。The uterine involution is a paramount period for the dairy cows after calving. The time of uterine involution affects the first postpartum estrus directly. To study the change rule of FSH and LH among the uterine involution, 15 postpartum dairy cows with the same age, parity as well as body condition were the same were selected in experiment. The concentration of FSH and LH was measured once every three days. The result showed that the chromes of FSH and LH kept declining in the early of uterine involution. Nevertheless, there was a peak in the 15d of uterine involution for the FSH. Then, the concentration of LH began to rise substantially at the 21d of uterine involution, there was a peak in the 24d of postpartum, from now on the concentration of FSH and LH produce little change.
