First, feeding method. Once the yak's breathing is normal after delivery, the yak should be fed to the colostrum in good time (best within 1 hour) and 5 kg in the next 24 hours to ensure adequate antibody protein. The optimum environment for newborn calves is 25°C. Therefore, thermal insulation, ventilation, light and good housing conditions should be given to gradually raise the ability of yaks to respond to the outside world. Calf colostrum fed to yak should be between 36°C and 38°C, in order to ensure milk temperature can be warmed by hot water bath. If milk is used to feed colostrum, it should be manually guided. Frail calves or calves that have been midwifery. Most of the first feedings are very weak and the amount of drink is small. They should have the patience to feed several times in a short time to ensure the necessary amount of colostrum. It should be fed a second time after 4 to 5 hours, and then fed three times a day. The temperature during feeding is maintained at 35 to 38°C. The hypothermia colostrum must be warmed to prevent the yak's gastrointestinal motility and lead to diarrhea. Conversely, if the temperature is too high, the stomatitis may occur due to overstimulation, or the calf may refuse to eat colostrum. During the period of colostrum every feeding of 1 to 2 hours, should drink warm water (35 °C ~ 37 °C) for water. Second, the amount of feeding. Should be based on the weight of the calf, each time the amount required is different (1.25 to 2.5 kg), should be fed 3 to 4 times within 24 hours, each feeding amount can not exceed the calf's stomach volume (5% of body weight) . Third, feeding utensils need to be disinfected. All containers must be thoroughly cleaned and sterilized before and after the feeding of the primary fluid to cut off the route of transmission of the bacteria. When raising calves, several points should be taken care of: selection of breeders; supplement of calves with drinking water; utensils used for milking of calves, should be carefully washed and disinfected with water above 40°C after each feeding.
