摘　　要：作者综述了2007～2008年脂溶性和水溶性维生素在反刍动物上的研究进展。VA可提高反刍动物的免疫功能，影响牛肉品质和反刍动物脂肪组织的发育，不同来源的VA的生物学活性有差异；VD3可提高奶牛免疫力，VD3的吸收率优于VD2，提高血清中25（OH）D3的浓度，影响牛肉品质；VE可提高产奶量，降低乳房炎、胎衣不下等疾病的发病率，刺激生殖器官发育，改善牛肉品质。烟酸不仅能缓解热应激对奶牛生产性能的影响，还能减少血浆中游离脂肪酸的浓度，从而减少脂肪肝的发生。VB12能促进葡萄糖的代谢，提高初生羔羊的生命力。胆碱能提高奶牛的生产性能，增加产奶量、乳蛋白和乳脂，并影响奶牛的繁殖性能。经过包被的VC有较好的过瘤胃能力，能更多的在肠道被吸收，促进奶牛对VC吸收。Research advance of fat-soluble and water-soluble vitamins,vitamin A, vitamin D,vitamin E from 2007 to 2008 has been reviewed in this article. Vitamin A can improve the immune function of ruminants and impact on beef quality and the development of ruminant adipose tissues. Sources of vitamin A have various biological avtivities vitamin D3 whose absorption is better than vitamin D2, has the ability of raising the immunity of dairy cattle, and increase the density of 25 （OH）D3 in the sera, which has some effects on the beef quality vitamin E can elevate the milk production, rectuce the incidence of afterbirth, and other, and stimulate the development of reproductive organs, resulting in the improvement of beef quality. Niacin can not only alleviate the effects of heat stress on the performance of dairy cattle, but also reduce the concentrations of free fatty acids in plasma decressing the incidence of fatty liver. Vitamin B12 can promote glucose metabolism and enhance the vitality of new born lambs. Cholinergic can improve the production, milk fat and protein and affect the reproductive performance of dairy cattle. Coated vitamin C has good ability to pass the rumen and can be more in the intestinal tract, which furtherty the absorption of vitamins by dairy cows.
