摘要
作者综述了2008-2009年维生素在反刍动物中的研究进展。维生素A可提高反刍动物的免疫功能,影响反刍动物脂肪组织的发育,具有抗氧化作用;维生素D3能提高奶牛血浆中钙、磷水平,提高血清中25-(OH)D3的浓度,影响牛肉品质;维生素E能提高肉牛的生产性能、奶牛的产奶量,降低繁殖疾病的发病率,刺激生殖器官发育,改善繁殖性能。烟酸能提高牛的生产性能,提高T3、T4水平;叶酸和维生素B12合用能增加牛奶中乳糖、蛋白质及总固形物的产量;胆碱可缓解奶牛产后能量负平衡状态。
Research advance of vitamins from 2008 to 2009 has been reviewed in this article.Vitamin A can improve the immune function of ruminants and influence on the development of ruminant adipose tissues and shows a high antioxidation activity.Vitamin D3 can raise the concentration of Ca,P in plasama,and increase the density of 25-（OH）D3 in the serum,which has some effects on the beef quality.Vitamin E can improve the performance of beef cattle,elevate the milk production,reduce the incidence of breeding,and stimulate the development of reproductive organs which results in the improvement of breeding performance.Niacin can not only improve the performance of dairy cattle,but also increase the concentrations of T3,T4 in serum.Supplementing folic acid and vitamin B12 can raise the product of lactose,crude protein,and total solid yield in milk.Choliner can release negative energy balance of postpartum dairy cattle.
