摘　　要：为研究维生素E和硒对围产期奶牛健康的影响,试验选择年龄、胎次相同,预产期相近的中国荷斯坦奶牛40头,随机分成2组:试验组为自由舔饲维生素E富硒舔砖组,对照组为不补饲维生素E富硒舔砖组,试验期90d(从预产前60d到产后30d)。结果表明,试验组奶牛血液中维生素E的含量在产后12h和产后30d均显著高于对照组(P<0.05),血液中硒的含量在产前30d、产后12h和产后30d均显著高于对照组(P<0.01)。试验组奶牛乳房炎、胎衣不下、子宫内膜炎疾病的发病率分别比对照组降低83.3%、80%、75%。To investigate effects of vitamin E and selenium on peripartum diseases,40 Holstein cows were randomly allotted to 2 groups based on ages,parity,and the expected calving period.Cows of the control were fed total mixed ration （TMR）,and cows of the trail group were fed TMR with licked brick contain vitamin E and seleninm.Experimental period was 90 days,including 60 days pre-calving and 30 days post-calvlng.The results showed that ：vitamin E in blood at 12 h and 30 d post-calving of dairy cows in trail group were obviously higher （P 〈 0.05） than those of the control.At 30 days pre-calving, 12 h and 30 d post-calving,the content of selenium in blood of dairy cows in trail group significantly in- creased than those of the control （P 〈 0.01 ）.The incidence of retained placenta,clinical mastitis and endometritis of dairy cow fed with bricks decreased by 83.3 %,80 % and 75 % than those of the control,respectively.
