Abstract
To declare the ovarian and hormonal changes during the transition from the anestrus to the cyclic state, five postpartum goats were daily examined by ultrasound. Two waves of follicular growth were followed and emerged 5.20±0.37days before and 2.2±0.37days after LH peak. The corpus luteum attained its widest diameter on Day4.71±0.36. The total inhibin secreted during the luteal phase was higher than that of the periovulatory period. Plasma LH levels showed an increase above basal levels on Day 0 and Day 8. Prolactin levels showed a noticeable declined (-40%) in most of the ovulated goats on the day of LH peak. Conclusion: the decreased prolactin and an increased of LH levels might induced the ovulatory event in the anestrus goats.
