| 摘 要： | 分娩母猪母性行为的好坏直接影响到仔猪的成活率,尤其是一些母性行为失常的母猪直接咬死、踩死、压死仔猪,给养猪业造成巨大的经济损失。母猪分娩是受多种因素如神经、内分泌和胎儿等多方面影响和调控的一个复杂过程。近几年,虽然许多专家对分娩的机理进行研究,但到目前为止对造成母猪母性行为失常原因及机理的了解还不是很清楚。就分娩环境、机体内分泌、母猪遗传背景及产仔经验等影响分娩母猪母性行为的4个主要因素进行综述和讨论。

| Abstract: | The maternal behavior of sows during parturition directly affects the survival rate of piglets,especially,the failure sows with distorted maternal behavior will kill the piglets by biting,trampling and crushing thus leading to a big economic loss for the breeder.The parturition is a complex proceeding,which is affected and regulated by lots of factors such as neural system,endocrine and foetus.In recent years,many experts have studied the mechanism of farrowing,but have not clearly understood the reasons and mechanism of sow maternal behavior distortion.In summary,the maternal behavior was affected by farrowing environment,neuroendocrine,genetic background and farrowing experience.In this paper,these four factors that influence the sow maternal behavior are summarized and discussed. |
