【摘要】：母畜在整个发情期都伴随着生殖器官的组织变化和内源激素及外表行为的变化。许多因子如光照变化、品种及年龄、群体密度及群内等级、环境温湿度、营养水平、公畜效应及饲养条件等都会影响母畜的生殖激素分泌以及发情行为的启动、发情表现及发情时长等。在现代畜牧业生产中研究并利用影响家畜发情因素,对于改善动物福利、缩短生产周期、提高母畜繁殖力,进而提高养殖经济效益具有重要的实践意义。因此,本文阐述了影响母畜发情因素及相应内分泌机理的研究进展,以期为家畜发情研究提供参考和借鉴。
[Abstract]:During the whole estrus, female animals were accompanied by changes in the tissues of reproductive organs, endogenous hormones and appearance behavior.Many factors, such as light variation, variety and age, population density and class, environmental temperature and humidity, nutrition level, effect of male animals and feeding conditions, all affect the secretion of reproductive hormones and the initiation of estrous behavior in female animals.The performance of estrus and the length of estrus, etc.It is of great practical significance to study and utilize the factors affecting the estrus of domestic animals in the production of modern animal husbandry to improve the welfare of animals, shorten the production cycle, improve the reproductive power of female livestock and further improve the economic benefit of breeding.In this paper, the factors affecting estrus and the corresponding endocrine mechanism are reviewed in order to provide reference for the study of estrus in domestic animals.
