Abstract
The influence of the presence of the male on the ovulation process was investigated in ewes after oestrus control by progestagens (intravaginal fluorogestone acetate) and PMSG. Permanent contact with the rams throughout oestrus accelerates the ovulation and the appearance of the LH surge. The results suggest that the action of the presence of the male on ovulation is mediated by way of the ovulatory surge of LH.
摘要
通过孕激素（阴道内植入醋酸氟孕酮）和孕马血清促性腺激素控制发情后，研究了公羊的存在对母羊排卵过程的影响。在整个发情期与公羊持续接触可加速排卵和促黄体生成素高峰的出现。结果表明，公羊存在对排卵的作用是通过促黄体生成素的排卵高峰介导的。
