The quality of yak rearing is directly related to the milk production level and reproductive performance of adult yaks. Therefore, the adult cows must be able to raise their calves during the yak period for high yields.
First, do a good job for the management of newborn calves
After the yak is removed from the mother, it is necessary to first clear the mucus and mucus and gently press the lungs to prevent the mucus from entering the trachea and suffocating. The yak's umbilical cord was cut at a distance of 10 cm from the abdomen, and the mucus in the umbilical cord was squeezed out and soaked in 5% iodine for 1-2 minutes to prevent infection. It is best to keep the cows clean in the other parts of the yak body. If necessary, wipe off with a clean, soft cotton cloth to prevent calves from getting cold.
Second, ensure that calves eat good colostrum
Colostrum contains higher protein, fat, vitamins and other nutrients than regular milk. It is the only full-price natural food after calf's birth. Colostrum also contains a large amount of immunoglobulins and lysozyme, which can kill and inhibit bacteria, play a role in laxation, enhance the immune function of calves, and promote normal activities of digestive function. The newborn yak's stomach is empty and the stomach wall is mucous. The resistance to bacteria is very weak. The content of colostrum immunoglobulin is high. Colostrum can replace stomach mucus and stick to the stomach and intestines, preventing bacteria from entering the bloodstream. Therefore, we must try to allow calves to eat early after birth, eat more colostrum, the sooner you eat, the faster calves gain weight, the stronger the constitution, the higher the survival rate.
Third, strengthen the exercise of digestive organs
1. Calves feed 4 days after birth. At the beginning of the test, a small amount of wet material is wiped into its mouth, and fresh dry yak material can also be placed in the feed box to give only the amount of finished food per day.
2. The yak around the age of one week can feed roughage. The calf's rumen activity increases with the increase of the amount of grass or hay. Generally, the calf can be trained to eat high-quality green hay in the second week after birth, and a small amount of high-quality green hay is placed in front of the bullpen, and the calf will try to eat. One point, gradually it will gradually increase the intake of food with the needs of physical development.
3. Yaks are fed with juiciness after 20 days. Every day, 20-25 grams of chopped carrots or other vegetables and grass are added to the concentrate, and they are gradually increased. They are fed 1-1.5 kg per day at 3 months of age.
4. Yaks began to feed silage at 2 months of age. Feeding 100-150 grams a day, gradually increasing the amount of feed, feeding 1.5-3 kg per day at 3 months of age, feeding 4-5 kg ​​per day at 4-6 months of age.
Fourth, do a good job of daily management
1. Environmental health
Newborn calves do not have any resistance to disease. Yak feeding rooms should be flat, dry, clean, and ventilated. The bedding should be changed frequently, and the excrement must be promptly removed, and lime should be disinfected after removal.
