The nose baffles are hung between nasal speculums of weaned yak calves, so that the yak calves are prevented from sucking breast milk, the technical measure of weaning is achieved, and weaning of the yak calves is facilitated by taking the measure while grazing yaks in the Qinghai-Tibet Plateau. Within 12-16 days after weaning, the aims of stimulating oestrus and ovulation of female yaks, mating and reproducing are achieved. With the adoption of the weaning technology, group grazing and eating of grass and supplementary feed of the yak calves are not influenced under the condition that the yak calves are prevented from sucking the breast milk, and the nose baffles are rem
