The possibility of using cervical mucus and vaginal cytology as tools to predict ovulation time was assessed in 11 ewes and 11 does raised under tropical conditions. Every 12 h from progesterone removal to ovulation, estrus behavior, cervical mucus, vaginal cytology, and ovarian ultrasound exams were performed. In goats, vaginal cytology had 88% of accuracy on detecting the ovulation time. However, in sheep, there was no cell pattern in the vaginal cytology and cervical mucus varied at ovulation. In conclusion, both vaginal cytology and mucus evaluation may be useful tools to determine the ovulation time in goats; however, both strategies are less accurate in sheep.
本研究评估了利用宫颈黏液和阴道细胞学检查来预测排卵时间的可能性，共纳入了 11 只绵羊和 11 只山羊。从孕酮去除到排卵期间，每 12 小时进行一次发情行为、宫颈黏液、阴道细胞学和卵巢超声检查。在山羊中，阴道细胞学检查对排卵时间的准确率为 88%。然而，在绵羊中，阴道细胞学检查没有细胞模式，排卵时宫颈黏液变化。综上所述，阴道细胞学和黏液评估都可能是确定山羊排卵时间的有用工具，但在绵羊中这两种策略的准确性都较低。
