摘　　要：作者尝试在非繁殖季节应用外源促性腺激素对家猫进行人工诱导发情,并判断其较为准确的排卵时间。试验采用PMSG两次注射法对雌性家猫进行诱导发情,注射总剂量为150 IU,PMSG处理后的第6 d肌肉注射hCG(100 IU/只)并合笼配种。分别于合笼后的24、30、36 h手术法摘除家猫卵巢及输卵管部,观察记录卵巢排卵情况并对排卵侧的输卵管进行冲胚。试验结果显示,利用外源性促性腺激素可使家猫在非繁殖季节发情,且排卵时间范围为合笼配种后30 h左右。The aim of this study is to determine the ovulation duration of domestic cats after superovulation during their non-breeding seasons . After the treatment with twice injection of 150 IU of pregnant mares＇ serum , the hot queens were injected with hCG（100 IU per cat）after the treatment with PMSG and allowed to coitus with males in following 24 h. The ovulation assessment was initiated in 24 h,30 h and 36 h after the first copulation by ovariohysterectom, and the embryos were recovered from the oviducts. The results showed that all adults responded with artificially induced estrus during the non-breeding seasons, and the ovulation in most queens was mainly initiated in 30 h after the first copulation.
