The anti-gonadal or anti-gonadotropic actions of prolactin in Japanese quail (Coturnix coturnix japonica) were re-investigated. Treatment of mature regularly laying quail with 16 I.U. of ovine prolactin (NIH-P-S11) per day for 7 or 14 days caused significant (P less than .05) decreases in ovarian and oviductal weight and a reduction in egg production by the third day of treatment. The most frequent response to prolactin was complete cessation of ovulation for the duration of the experiment, but some birds showed no effects from the hormone treatment. Prolactin caused a significant (P less than 0.05) increase in body weight of the quail. Serum LH, measured during the expected time of the preovulatory LH surge, was significantly lower in birds treated with prolactin the day before sampling than in control birds. It was concluded that prolactin has a distinct anti-gonadal or anti-gonadotropic action in this species.
对催乳素在日本鹌鹑（Coturnix coturnix japonica）体内的抗性腺或促性腺激素作用进行了重新研究。用16国际单位的绵羊催乳素（NIH - P - S11）每天对成熟且规律产蛋的鹌鹑进行处理，持续7天或14天，在处理的第三天就导致卵巢和输卵管重量显著（P小于0.05）下降，产蛋量减少。对催乳素最常见的反应是在实验期间完全停止排卵，但有些鸟类对激素处理没有反应。催乳素使鹌鹑体重显著（P小于0.05）增加。在预期的排卵前促黄体生成素（LH）激增时间测量血清LH，在采样前一天用催乳素处理的鸟类中，其血清LH显著低于对照鸟类。得出的结论是，催乳素在该物种中具有明显的抗性腺或促性腺激素作用。
