我们研究了外周血中的阿糖胞苷A，总阿糖胞苷，类固醇和促性腺激素浓度的变化，在整个完整的发情周期的母猪卵巢的变化，每天经直肠超声检查。所有直径大于或等于3 mm的可见卵泡均被归类为小卵泡（>= 3 mm和= 6 mm）。卵泡募集在周期的两个时期被确定：一个是从黄体晚期到卵泡期，其特征是小卵泡数量增加，随后出现大卵泡;另一个是在黄体早期，仅包括小卵泡数量增加。血浆白蛋白A浓度升高（P
We investigated changes in peripheral concentrations of inhibin A, total inhibin, steroids, and gonadotropins throughout the intact estrous cycle of the sow in relation to ovarian changes determined by daily transrectal ultrasonography. All visible follicles of 3 mm or more in diameter were classified as small (>= 3 and = 6 mm). Follicular recruitment was identified in two periods of the cycle: one from the late luteal to the follicular phase, characterized by an increase in the number of small follicles followed by the appearance of large follicles; and another during the early luteal phase, consisting only of increased numbers of small follicles. Plasma concentrations of inhibin A increased (P
