The objective of the present study was to evaluate the effect of oils for sows during late pregnancy and lactation on offspring performance. In addition, the effect of caprylic acid (C8) or medium-chain triglyceride oil (MCT) in piglets' feed on their gut development, performance, and health status was determined. The experiment was conducted on 24 sows allocated to two treatments: diet with rapeseed oil or with coconut oil. Newborn piglets were randomly allocated to three treatments: feed with no supplement or supplemented with 0.3% MCT or with 0.3% C8. The results showed that both oils had no effect on sow reproductive rates; however, fatty acid patterns of milk differed significantly and the number of lost piglets was lower in sow fed with coconut oil. Both caprylic and MCT oil significantly improved piglet performance and villus height. These additives did not change triacylglycerol content in blood, but C8 lowered total cholesterol and MCT increased IgG content. It can be concluded that coconut oil fed to pregnant and lactating sows can markedly reduce the mortality of piglets and that caprylic acid and medium-chain fatty acid oil can be a good supplement in weaned piglet feed.
本研究的目的是评估妊娠后期和哺乳期母猪食用油对后代性能的影响。此外，还测定了仔猪饲料中辛酸（C8）或中链甘油三酯油（MCT）对其肠道发育、性能和健康状况的影响。实验选取24头母猪，分为两种处理：分别饲喂菜籽油或椰子油的日粮。新生仔猪随机分为三种处理：不添加任何补充剂的饲料，或添加0.3% MCT或0.3% C8的饲料。结果表明，两种油对母猪繁殖率均无影响；然而，乳汁中的脂肪酸模式存在显著差异，饲喂椰子油的母猪所产仔猪的死亡数量较少。辛酸和MCT油均显著提高了仔猪性能和绒毛高度。这些添加剂并未改变血液中的三酰甘油含量，但C8降低了总胆固醇，MCT增加了IgG含量。可以得出结论，给怀孕和哺乳母猪饲喂椰子油可显著降低仔猪死亡率，辛酸和中链脂肪酸油可作为断奶仔猪饲料的良好补充剂。
