The invention discloses a method for raising cows capable of producing selenium-rich milk and belongs to the technical field of cow raising. The raising method comprises the following steps: each cow in a lactation period is fed with selenium yeast in the adding amount of 20-30 mg/day, the content of vitamin E, zinc sulfate monohydrate and manganese sulfate monohydrate in feed is changed 40 days after feeding starts, and then the cows are fed with the feed with changed composition until the lactation period ends. With adoption of the method, the content of selenium in the milk produced by the cows can keep higher level for a long time, the feeding cost is low, and the method is applicable to production of the selenium-rich milk. 本发明公开了种产富硒牛奶的奶牛饲养方法，属于奶牛饲养技术领域。本发明所提供的饲养方法是利用酵母硒以20-30mg/头日的添加量饲喂泌乳期奶牛，在饲喂开始40天后改变饲料中的维生素E、水硫酸锌和水硫酸锰的含量，然后以改变组成后的饲料饲喂至泌乳期结束。本发明所提供的方法能够使奶牛所产的牛奶中硒含量长期保持较高水平，且饲喂的成本低廉，特别适用于富硒牛奶的生产。
