摘　　要：维生素D(VD)是维持动物机体健康稳定的一种脂溶性营养素,可以通过调节钙、磷稳态以及骨骼肌发育和免疫系统等改善动物机体的健康。VD_(3)及其代谢产物25-羟基维生素D_(3)(25(OH)D_(3))在猪日粮中的应用也格外受到重视。VD可以通过调节仔猪免疫反应,抑制病原微生物感染,缓解生长受阻;可以通过其较强的抗氧化能力,改善肌肉品质;在妊娠和哺乳日粮中补充VD,可以改善母猪繁殖性能和泌乳性能,增加后代仔猪血液中25(OH)D_(3)的水平。文章就VD在仔猪、生长育肥猪和种猪生产中的应用效果进行综述,为VD在生猪实际生产中的应用提供参考。Vitamin D is a fat-soluble nutrient that maintains the health of animals.It can improve pig health via modulating calcium and phosphorus homeostasis,skeletal muscle development and the immune system.In recent years,the application of vitamin D_(3) and 25-hydroxyvitamin D_(3) in pigs has attracted the attention of scientists.VD can regulate the immune response of piglets,inhibit the infection of pathogenic microorganisms and relieve growth retardation,improve muscle quality through its strong antioxidant capacity,supplementation of VD in pregnancy and lactation diets can improve reproductive performance and lactation performance of sows and increase blood levels of 25(OH)D_(3) in offspring piglets.In the paper,the application effect of VD in the production of piglets,growing-finishing pigs and breeding pigs was reviewed,which provided reference for the application of VD in the actual production of pigs.
