摘　　要：母体效应是指子代畜禽的某些外形特征、生理性状及生产性能受其母体直接影响的一种生理现象。胚胎在母体子宫内发育期间,细胞有序地增殖分化,逐渐形成各种组织、器官和系统。母体营养是母体效应发挥作用的主要方式,母体在妊娠期和哺乳期摄取的氨基酸、葡萄糖、脂肪酸、微量元素、维生素等营养物质,会对其子代的生长发育产生一定的影响,进而影响其性状。现从畜禽母体营养对其子代性状的影响及其表观遗传分子机制的研究进展进行综述,为今后研究畜禽生产性能的提高和母体营养对子代性状的影响提供理论参考。Maternal effect refers to a physiological phenomenon that some appearance characteristics,physiological traits and production performance of offspring in livestock and poultry are directly affected by their mothers.During the development of the fetus in the womb,cells proliferate and differentiate in an orderly manner,and gradually form various tissues,organs and systems.Maternal nutrition is the main way by which the maternal effect works.The nutrients such as amino acids,glucose,fatty acids,trace elements and vitamins taken by the mother during pregnancy and lactation,will have a certain effect on the growth and development of its offspring,and then influence its traits.Therefore,this paper reviews the research progress of the effects of maternal nutrition on traits of its offspring and its epigenetic molecular mechanism.Furthermore,it also provides a theoretical basis for researching the improvement of livestock and poultry production performance and the effect of maternal nutrition on offspring traits in future.
