| 摘 要： | 绵羊是一种短光照型生殖动物，具有明显的生殖季节性。人们普遍认为，绵羊生殖周期与环境光周期的同步变化是通过褪黑素作用于下丘脑－垂体－性腺轴系统来实现的。近年来的不少研究结果表明，绵羊对光周期的感受性还受褪黑素受体的调控。现从生态学（光周期的生殖效应）、神经内分泌学和分子生物学（褪黑素受体）等领域的研究进展出发，对褪黑素调控绵羊自然季节性生殖的作用及机制进行系统综述。

| Abstract: | Sheep,beginning its breeding season in the autumn ,is considered to be a short day breeder.It is generally postulated that the pineal hormone melatonin synchronizes ovine reproductive cycle with environmental photoperiod through neuroendocrine changes in the hypothalamo pituitary gonadal axis.A lot of recent studies demonstrated that melatonin receptor was involved in the photoperiodism.This paper,based on the research progress in ecology,neuroendocrinology and molecular biology,reviews the regulative effect and mechanism of melatonin in the natural seasonal reproduction of sheep. |
