Seventy-three Standardbred and Thoroughbred mares in clinical anoestrus during the breeding season were treated with PGF2alpha. The mares were divided into four categories; foaling, barren, maiden and unknown. The response was consistent in all groups. Mares at Days 2 to 4 of dioestrus showed no decrease in plasma progesterone levels, and those at Days 6 to 8 showed a return of progesterone to baseline levels (less than 1 ng/ml) in 24 to 48 hr after treatment. Plasma progesterone levels returned to basal levels in 24 to 48 hr in 93% of mares; progesterone levels had not changed by 96 hr in 7% of the treated mares. Behavioural oestrus was detected in 71% of treated mares an average of 4-4 days after treatment, and ovulation occurred in 86% at an average of 8-9 days. Pregnancy occurred in 55-5% of the PGF2alpha-treated mares after an average of 1-7 services during the induced oestrus.
在繁殖季节处于临床乏情期的73匹标准赛马和纯种母马接受了前列腺素F2α治疗。这些母马被分为四类：已产驹、未孕、处女马和情况不明。所有组的反应一致。处于间情期第2至4天的母马血浆孕酮水平没有下降，而处于第6至8天的母马在治疗后24至48小时内孕酮恢复到基线水平（低于1纳克/毫升）。93%的母马血浆孕酮水平在24至48小时内恢复到基础水平；7%的治疗母马在96小时时孕酮水平没有变化。71%的治疗母马在治疗后平均4.4天出现行为性发情，86%的母马平均在8.9天排卵。在诱导发情期间平均经过1.7次配种后，接受前列腺素F2α治疗的母马中有55.5%怀孕。
