| 摘 要： | 奶牛乳腺健康直接关系到奶牛生产性能,和牧场效益息息相关。如何有效预防奶牛乳房炎的发生,是牧场的重中之重。干奶期是奶牛乳腺机能恢复健康的一个重要阶段,对预防奶牛产后乳房炎的发生有着重要意义。本文利用长达1 年的时间,对635 头奶牛进行分组试验,并追踪观察其产后90 天内乳房炎的发生情况和产奶量情况。通过数据分析发现,奶牛干奶期联合使用抗生素和乳头封闭剂对奶牛进行干奶,比单独使用抗生素干奶,产后7 天的体细胞阳性率降低了28.58%;产后60 天临床乳房炎发病率降低了35.40%,产后90天降低了41.32%;各组之间的产奶量并无显著差异（P>0.05）。

| Abstract: | Dairy cow breast health is directly related to the production performance of dairy cows and the benefits of pasture. How to effectively prevent the occurrence of mastitis in dairy cattle is the top priority of the ranch. The dry milk period is an important stage for dairy cows to recover their mammary gland function,which is of great significance to prevent the occurrence of postpartum mastitis. In this paper,635 cows were divided into groups for one year,and the incidence of mastitis and milk production were observed in 90 days after delivery. Through data analysis,it was found that the positive rate of somatic cells at 7 days after delivery was reduced by 28.58% when the cows were dried with antibiotics and nipple sealer in the dry milk period compared with the dry milk with antibiotics alone. The incidence rate of clinical mastitis decreased by 35.40% at 60 days postpartum and 41.32% at 90 days postpartum.There was no significant difference in milk yield between the groups （P > 0.05）. |
