硒对母猪氧化应激及其后代抗氧化能力的营养调控研究

硒作为的重要微量元素之一,可以通过胎盘和乳组织进行转移.仔猪可以从乳汁中获取硒源,提高硒含量,进而提高仔猪的初生重.同时,硒也能够调节母猪妊娠期间代谢速度,控制妊娠期自由基产生,进而提高胎盘输送营养功能.文章从母猪氧化应激体系角度来解析硒对母猪妊娠期氧化应激的调控机制、硒对哺乳母猪生产性能的调控作用.

Research on nutritional regulation of selenium on oxidative stress and antioxidant capacity of sows offspring

As one of the important trace elements, selenium can be transferred through the placenta and milk tissue.Piglets can obtain selenium sources from milk, which can improve the piglet’s newborn weight. At the same time,selenium can also adjust the metabolic speed during pregnancy, control free radical production during pregnancy,thereby increasing placenta delivery nutrition. The paper analyzes the regulatory mechanism of selenium on sow gestational oxidative stress from sow oxidation angle, and analyzes the regulation of selenium on the production of breastfeeding sow.
