This systematic review analyzed the effect of selected nutrients and additives in the feed of pregnant sows on the survival of newborn piglets. We analyzed 720 peer-reviewed publications in English in PubMed and Web of Science, dated July 2023 to January 2024, related to the effect of dietary supplementation with fatty acids and various percentages of protein, amino acids, and/or sources of dietary fiber on the offspring of gestating sows. While several papers evaluated the effect of nutrition on gestating sows, only a few delved into the distinct feeding strategies required at each stage of gestation to meet the NRC's nutritional requirements for maternal tissue gain and postnatal neonatal survival and growth. This body of research suggests that as gestation progresses the sow's nutritional requirements increase, as the NRC established, to satisfy their own metabolic needs and those of their fetuses. Additional research is needed to determine an optimal feeding strategy.
本系统评价分析了妊娠母猪饲料中特定营养素和添加剂对新生仔猪存活率的影响。我们在PubMed和Web of Science中分析了720篇2023年7月至2024年1月期间以英文发表的同行评审出版物，这些出版物涉及脂肪酸、不同比例的蛋白质、氨基酸和/或膳食纤维的膳食补充对妊娠母猪后代的影响。虽然有几篇论文评估了营养对妊娠母猪的影响，但只有少数论文深入探讨了妊娠各阶段为满足美国国家研究委员会（NRC）对母体组织生长以及产后新生仔猪存活和生长的营养需求而需要的不同饲养策略。这一系列研究表明，随着妊娠进展，母猪的营养需求会增加，正如NRC所确定的，以满足它们自身的代谢需求以及胎儿的需求。需要进一步的研究来确定最佳饲养策略。
