摘　　要：中国规模化猪场母猪年提供的断奶仔猪数(PSY)及产肉量比欧美发达国家低30%～40%,究其原因在于品种选育、营养与饲养管理、疾病防控等各环节的不足。妊娠母猪的受胎率、早期胚胎存活、胎儿的生长发育受到营养及饲养管理的显著影响,是决定母猪繁殖效率的关键原因。国际国内考察营养对妊娠母猪繁殖性能的影响所涉及的营养素以能量、氨基酸、功能性添加物为主,而维生素、微量元素方面的研究较少。本文重点综述了近年来营养对妊娠母猪繁殖力的调控效应,为养猪生产者制定合理的营养与饲养管理程序提供参考。The number of weanling piglets and offspring meat production per sow per year is about 30%~40% lower in China compared with that in western countries, which is mainly attributed to the inade quacy in breeding, nutrition, management and disease control. The conception ratio, early embryonic survival and intrauterine fetal growth were profoundly affected by nutrition in gestation sows, and are key determinants of their reproductive performance. The nutritional regulations of fertility in gestation sows mainly focused on dietary energy, amino acids, functional additives, but the researches related to vitamins and minerals were limited. The current reviews summarized recent advance in the nutrient- dependent regulations of gestation sows, which would provide insights for the swine producers to estab olish optimum nutritional and management strategies.
