Cow yak weaning skills
There are two ways to raise normal weaned calves: one is 110 days weaning, the 6-month-old body weight is 170 kg, and the average daily gain is 700-730 grams; the other is 60 days weaning, 6 months old body weight 160-165 In kilograms, the average daily gain is 670-700 grams.
Feeding method
The amount of colostrum produced by each cow is 110-140 kg, while the yak born only eats 20-24 kg in 3 days, and the remaining colostrum is preserved. Fermented colostrum is naturally fermented at 25 ° C to 30 ° C. Add yak to the 1:1 ratio and add water, then add equal amount of hay or 4 to 5 times of silage and mix well until the amount of food is kept at 2 kg per head per day. Feeding should be timed, fixed temperature, quantitative and fixed breeder, that is, when feeding the calf, the temperature should be constant. Generally, the temperature of the milk should be between 35 °C and 38 °C. The temperature should not be high or low, and the amount of milk should not be too small. The amount of milk should be fixed, and it should be fed by a special person as much as possible so that the yak can be digested normally. Soak the utensils with hot water before each feeding. After feeding the milk, wipe the residual milk from the yak mouth with a dry towel. In the process of weaning weaning, in order to prevent yak squatting, appropriate antibiotics can be added during the feeding process, and the refueling is gradually carried out. During this period, the hay is for free feeding, and the amount of drinking water should be gradually increased.
The management technology keeps the ventilation inside the barn , so that the yak is more exposed to the sun, and the temperature of the barn is preferably 10 °C ~ 24 °C. In the 10-15 days after the birth of the yak, the yak is removed in time to reduce the absorption of nutrients by keratin growth and accelerate the growth and development of the yak . It is kept in the yak bar (outdoor or indoor) within 3 months of age. Cold-breed outdoor yak method can help improve survival rate and disease resistance; after 3 months of age, it can be transferred to group feeding, strengthen exercise, and do a good job of yak brushing. Yaks are not to be raised and should be kept in fences for free movement.
