Abstract：
The energy and metabolic state of sows will alter considerably over different phases of gestation. Maternal metabolism increases dramatically, particularly in late pregnancy. This is accompanied by the development of an increase in oxidative stress, which has a considerable negative effect on the maternal and the placenta. As the only link between the maternal and the fetus, the placenta is critical for the maternal to deliver nutrients to the fetus and for the fetus\' survival and development. This review aimed to clarify the changes in energy and metabolism in sows during different pregnancy periods, as well as the impact of maternal oxidative stress on the placenta, which affects the fetus\' survival and development.
摘要：
母猪的能量和代谢状态将在妊娠的不同阶段发生相当大的变化。母体新陈代谢急剧增加，特别是在怀孕后期。这伴随着氧化应激增加的发展，这对母体和胎盘有相当大的负面影响。作为母亲和胎儿之间的唯一联系，胎盘对于母体为胎儿提供营养以及胎儿的生存和发育至关重要。本文旨在阐明母猪在不同孕期能量和代谢的变化。以及母体氧化应激对胎盘的影响，影响胎儿的生存和发育。
