摘要/Abstract

摘要：

光照是生物体重要的生活环境因素之一。禽类具有优越的感光机能，光线通过其光感受器被感知，并转变为生物学信号，从而对生长发育、繁殖和行为等方面产生影响。在现代养禽业中，人工优化光照环境已成为提高动物生产性能的一项重要手段。近年来，随着种用母鸡笼养、人工授精技术的广泛应用及精液处理、包装和存储技术的发展，在家禽养殖中，也逐步将种公禽单独饲养。研究光照对种公禽繁殖性能的影响，一方面可以进一步解析种公禽繁殖系统对光要素的生物应答机制，另一方面可为生产中采用精细化的光照条件提高种公禽繁殖效率提供科学依据。笔者就禽类的光感受器，参与光-性信号传导的激素，以及光照节律、光照强度和光波长对种公禽性成熟和繁殖性能的影响等方面的研究进展进行综述，以期为其在生产中的应用奠定基础。

Abstract:

Lighting is one of the most crucial environment factors for the organisms. The superior photonasty of poultry enable them to sensitize the lighting and translate the photon to biological signals that regulate the growth,reproduction and behaviors. In the modern poultry industry, providing the optimized lighting environment has been an important management strategy for the enhancement of the animal performance. In the recent years, with the development of poultry artificial insemination technology,semen process,package and conservation, housing the male breeders separately from the females is getting popular. Therefore,the finer lighting environment for the males is valuable for their reproduction performance. The recent progresses on poultry photoreceptor,hormones involved in the light-sex signal transduction, and the effect of lighting regimen, light intensity,and spectrum on the reproduction of male poultry breeders were summarized in this review,aiming at providing the basis for the future study and industry application.

Key words: male poultry breeder; lighting; reproduction; hormone
