给予合成GnRH150μg或300μg一次注射后,大多数非繁殖季节的母羊可产生排卵前型的LH峰与排卵,但LH峰只有动情期自然峰值的25%左右,且外周血中孕酮浓度表明完全缺乏黄体功能。在绵羊中,LH的分泌是脉冲式的。基值为0.1-2.0ng/ml,有散在的小而短暂的脉冲,每次为5-15ng/ml,持续约30分钟左右。在动情周期的黄体期或非繁殖季节中,LH脉冲发生不规则,间隔3-12小时。黄体退化后,LH脉冲发生频率增 Given an injection of either 50 μg or 300 μg of synthetic GnRH, most of the non-breeding ewes produce pre-ovulation LH and ovulation, but the LH peak is only about 25% of the natural peak in estrus and the progesterone concentration in the peripheral blood indicates complete Luteal function is lacking. In sheep, the secretion of LH is pulsed. Base values ​​of 0.1-2.0 ng / ml with scattered small and transient pulses of 5-15 ng / ml each for about 30 minutes. In the estrous cycle of the luteal phase or non-breeding season, LH pulse irregular, interval of 3-12 hours. Luteal degeneration, LH pulse frequency increased
