Abstract: Energy is the most important nutrient in the gestation stage of sows，providing fuel for sow maintenance growth，reproduction and lactation processes as well as physical activity. Accurate determination of the energy utilization of feed ingredients in sows at different growth stages can better meet the energy needs of pigs at different growth stages. This paper reviews the energy requirements of sows during gestation and lactation from four databases e.g. the Nutrient Requirements of Swine（NRC，2012），and effects of different energy substance additions on reproduction performance and physiological function of sows at different stages，to provide a theoretical reference for future research on the dynamic energy requirements of sows during reproduction.

摘要： 能量是母猪妊娠阶段最重要的营养物质，为猪的一切生命活动提供燃料。准确测 量母猪不同生长阶段饲料原料的能量利用率，可以配制更全面的饲料以满足猪不同生长阶段 的能量需求。该文综述了包括美国猪营养需要（NRC，2012）在内的四种数据库的妊娠期和哺 乳期母猪的能量需要量，以及研究不同能量物质添加对不同阶段母猪繁殖性能及生理功能等 的影响，为今后繁殖期母猪能量动态需要量研究提供了理论参考。
