摘要:

为了解绵羊母性行为及调节母性行为的神经内分泌、分子机制研究进展，以绵羊"母性行为，影响因素，神经内分泌，分子机制"为检索词，查阅绵羊母性行为相关文献资料。结果发现：绵羊母性行为的表达促进母子关系的建立，母羊品种、胎次、性情、产羔数、饲养面积以及妊娠期营养状况影响其母性行为的表达。母羊体内释放的激素（雌激素、催产素）和神经递质（谷氨酸、γ-氨基丁酸、一氧化氮、去甲肾上腺素）调控母性行为的发生，且DNA甲基化可能是调控母性行为的分子机制之一。绵羊母性行为的影响因素及神经内分泌调控机制研究已较为成熟，但关于调控绵羊母性行为的分子机制尚缺乏深入系统研究。

Abstract:

In order to explore the research progress on the maternal behavior of sheep,the influencing factors and the neuroendocrine and molecular mechanisms regulating maternal behavior,literatures related to sheep's maternal behavior were searched by using sheep's maternal behavior,influencing factors,neuroendocrine,and molecular mechanism as keywords.The results showed that:The expression of maternal behavior promoted the development of the mother-young interactions;Ewe breeds,parity,temperament,litter size,pen size and nutrition in pregnancy effected on the expression of maternal behavior;Hormones (estrogen,oxytocin) and neurotransmitters (glutamate, γ-aminobutyric acid,nitric oxide,noradrenaline) released in ewes regulated maternal behavior,and DNA methylation might be one of the molecular mechanisms regulating maternal behavior.It was found that the influencing factors and neuroendocrine regulation mechanism of sheep maternal behavior were fully investigated,while there was still a lack of the molecular mechanism of regulating the maternal behavior.

Key words: ewe maternal behavior neuroendocrine molecular mechanism
