The invention discloses a method for improving the reproductive rate of yaks through timely
weaning of calves, and relates to the technical field of yak breeding, and the method comprises the following specific steps: step 1, determining the
weaning time of yak calves in advance; the
weaning time range of the calf is estimated according to the age and
health condition of the calf and the
lactation capacity and feeding environment of the cow; 2, preparation before weaning of the calf; 3, feeding management in the weaning period: 8-14 days before weaning, the
breast milk intake of the calf is equivalently decreased, the proportion of feeding concentrated feed is synchronously and equivalently increased, and the feed
mass increased every time is 80-90% of the decreased
breast milk mass; and step 4, management after weaning of the calf. According to the method for improving the
reproduction rate of the yaks through timely weaning of the calves, the growth performance of the calves is improved, meanwhile, the
reproduction cycle of cows is accelerated, and therefore the
reproduction rate of the whole
cattle herd is improved, healthy growth of the calves is facilitated, the
lactation period and the breeding cycle of the calves are shortened, the breeding cost is reduced, and the income of herdsmen is increased.
