Cervical involution was showed in detail by using ultrasound scanner during its whole involuting phase, and the oestrus could be indicated by the differences of the ultrasonograms of the genital tract at the time. It took 46.7+3.9 days for the cervix to complete involution after calving, and its involuting rate was delayed by the occurence of the periparturient fatty liver and injury of the cervix during parturtion.展开更多

Meanwhile, the concentrations of progesterone and 17β-oestradiol in peripheral plasma of the cows were measured by radioimmunoassay (RIA). The resutis showed that the first postpartum ovulation was found in 67% of the cows on the ovary opposed to the gravid horn. The first dominant foillicles ovulated for the six of ten cows. The time intervals from calving to the first ovulation were significantly associated with the number of follicular waves (r=0.83, P<0.01). No difference between the diameters of the first and the second ovulated follicles was found in the study, however, the growth rates of the first and the second ovulated follicles were significantly different (P<0.05), and the concentrations of 17β-oestradiol prior to the first ovulation were significantly lower than that before the second ovulation.展开更多
