摘要/Abstract

摘要： 母猪繁殖性能的选育增加了产仔数,但产后5 d仔猪甚至断奶前仔猪死亡率高仍然是生产中主要面对的问题。母猪母性行为的好坏对仔猪的存活、生长发育及福利都有着重要的影响,从而影响养殖效益,因此对母猪母性行为的研究具有重要意义。母猪的母性行为主要包括产前筑窝、产后哺乳、抚育和护仔等行为。母猪母性行为的实施既通过神经和激素的共同作用和调节,同时也会受到遗传、环境等多种因素的影响。随着育种目标的调整及对动物福利的重视,母猪的母性行为受到越来越多的学者关注。作者对母猪母性行为的产生机制及影响因素等进行了综述,并对未来的研究方向进行了展望,旨在为后续母猪母性行为研究提供理论基础和研究思路。

Abstract: The breeding of reproductive performance in sows has increased litter size,but high mortality of piglets at 5 days postnatal and even before weaning is still a major problem in production.The maternal behaviors of sows have an important impact on the survival,growth and welfare of piglets,thus affecting the breeding benefits.Therefore,the study on sow maternal behavior is of great significance.The maternal behavior in sows mainly include prenatal nesting,postpartum lactation,rearing,litter care and so on.The maternal behavior in sows is regulated by the interaction of nerves and hormones,and is also influenced by genetic,environment and other factors.With the adjustment of breeding objectives and the importance of animal welfare,the maternal behavior in sows has been studied by more and more scholars.The author reviewed the domestic and foreign research progress on the mechanism and influencing factors of maternal behavior in sows,and prospected the future research direction,which providing a theoretical basis and research ideas for subsequent research of maternal behavior in sows.

Key words: sows; maternal behavior; regulation mechanism; influence factor
