1, early feeding colostrum. Colostrum contains higher protein, fat, vitamins and other nutrients than regular milk, but also contains a large number of immunoglobulins and lysozyme, which can kill and inhibit bacteria. Therefore, yak should be fed into colostrum as early as possible. Since the calves receive the strongest immunoglobulin absorption in colostrum 4-6 hours after birth, calves are fed colostrum about 1 hour after they are born, and they are fed for the second time in 6-9 hours. The amount of feeding is 2 kg. . Gradually increased later, lasting 5-7 days, feeding no more than 5% of body weight. 2, breast-feeding regular milk. After 5 to 7 days, the yak should be transferred to the yak house and fed with regular milk. It should be fed 3 times a day and the temperature should be maintained at 35--38°C. 3, timely feed intensive feed. One week after birth, calves started training for feed concentrates to supplement nutrition and promote gastrointestinal development. Feed 10 to 20 grams of concentrate each day for the first few days, and then gradually increase it to 80 to 100 grams. Feeding volume 200-300 grams per day for 30 days and 600-1000 grams for 60 days. 4, feed quality roughage. In order to promote the early development of the stomach, feed the roughage before the function of the digestive tract is perfect. One week after the yak is born, a small amount of high-quality hay can be fed freely in the trough. After 2 weeks, a small amount of chopped carrots, squash, and other green and juicy succulent fodder were allowed to feed in the trough, which increased to more than 2 kg after 60 days. Calves can be sprinkled with small amounts of silage in the troughs 20 to 30 days after they are born. Afterwards, it gradually increased. After 2 months, it can be fed 100-150 grams per day; in March, it can be fed 1.5-2 kg; from 4-6 months to 4-5 kg. 5, to the yak drink good water. The yak 15 days ago drinking water should be sterilized drinking water, and pay attention to the same temperature and milk temperature. After 15 days, use clean and warm water and change to tap water after 30 days, but be careful not to feed ice water and unhygienic water. 6, early weaning. Healthy and healthy calves can be weaned at 60 days of age. The specific method is to begin to increase the fine material and coarse material and reduce the amount of milk during the first half month of weaning. The number of feedings per day was changed from 3 to 2 times, and from 2 to 1 at the time of weaning, then the milk was stopped. Milk can also be mixed with milk to gradually reduce the amount of milk, and finally to all the water supply. It is generally believed that the amount of concentrate feed at weaning is about 1 kg per day. The 3-month-old concentrate is increased to 1.5-2 kg, and rough feed can be supplied in large quantities during this period. After 2 months of birth, they were allowed to freely feed quality roughage. The roughage should be about 1.7 kg per day. After 2 months, general roughage can be fed and controlled at 2 kg per day.
