The performance of high-yielding sows is directly related to the productivity of pig farming. Fetal development mainly occurs during the last month of pregnancy, and the aggressive metabolic burden of sows during this stage eventually leads to systemic oxidative stress. When affected by oxidative stress, sows exhibit adverse symptoms such as reduced feed intake, hindered fetal development, and even abortion. In addition, milk synthesis during the lactation period causes a severe metabolic burden. The biological response to oxidative stress during this period is associated with a decrease in milk production, which further affects the growth of piglets. Understanding the nutritional strategies to alleviate oxidative stress in sows is crucial to maintain their reproduction and lactation performance. Recently, advances have been made in the field of nutrition to relieve oxidative stress in sows during late pregnancy and lactation. This review highlights the nutritional strategies to relieve oxidative stress in sows reported within the last 20 years.

减轻母猪氧化应激的营养策略

高产母猪的生产性能直接关系到养猪业的生产力。胎儿发育主要发生在妊娠的最后一个月,母猪在此阶段的积极代谢负担最终导致全身性氧化应激。当受到氧化应激影响时,母猪会表现出不良症状,例如采食量减少、胎儿发育受阻,甚至流产。此外,哺乳期的乳汁合成会造成严重的代谢负担。在此期间对氧化应激的生物反应与产奶量减少有关,这进一步影响了仔猪的生长。了解缓解母猪氧化应激的营养策略对于维持其繁殖和泌乳性能至关重要。最近,在营养领域已经取得了进展,以缓解母猪妊娠晚期和哺乳期的氧化应激。这篇综述重点介绍了过去 20 年来缓解母猪氧化应激的营养策略。
