Yak feeding and management
Raising yaks should do a good job in breastfeeding, feeding, careful management and prevention of diseases and Other links. After feeding the colostrum, after the calf is born, wipe the mucus of the mouth and nose with a clean cloth or hay to facilitate breathing. The umbilical cord should be torn or cut in time, and sterilized with 5% iodine to prevent the occurrence of omphalitis, followed by weighing and numbering. When the yak wants to stand, it should assist in standing and help to suck colostrum. The calf from birth to weaning is generally called calf. It has fast growth and development, and has a strong metabolism. However, the digester palace is not yet fully developed, has weak adaptability, and has low resistance to the external environment. It should be carefully managed and supplied with nutritious and digestible food. Yak and meat yak should be allowed to milk with the cows. Milk calves should be isolated and artificial breast-feeding should be used. No matter if they are in service, meat or milk, their colostrum should be eaten as soon as possible. For the first time, they should try their best to drink enough to increase the disease resistance of calves. Improve health. Afterwards, 1/10 of the body weight can be used (ie, an average of 10 kg body weight can be fed 1 kg of colostrum per day) and be fed 2-3 times a day. In order to prevent calf diarrhea, 20-50 milligrams of oxytetracycline or chlortetracycline may be added to the milk. Yak milk temperature is generally about 37 °C is appropriate, too low milk temperature can easily cause diarrhea, hyperthermia will damage the gastric mucosa, but also cause digestive disorders. If there is no colostrum, it can be fed with the regular milk in the herd, but each day should be filled with cod liver oil or food containing vitamin A, and another 50 grams of sesame oil to replace the colostrum's laxative effect. Can also be fed artificial colostrum, the formula is: fresh eggs 2-3, salt 9-10 grams, 15 grams of fresh cod liver oil, add a liter of clean 40 °C -50 °C of boiling water, mix well. For 4-7 days, calves feed 8-10 milliliters per kilogram of body weight per day for half an hour before feeding. Feeding regular milk: After the end of the colostrum period, the mixed cow's milk in the herd is transferred. The lactation period is generally about four months. The total breastfeeding amount of each calf is about 400-450 kg. Yak used for meat and meat use mostly breastfeeding, usually weaning for six months. However, the specific length of time should also depend on the growth and development of yaks. Early feeding of botanical fodder: 10–15-day calves start training to eat plant-based fodder (including quality hay and concentrates) but must not feed rancid feed to prevent diarrhoea. After 20 days, a small amount of good quality succulent concentrate can be added to the mixed concentrate. Silages are fed from 2 months later. No matter whether they feed concentrates, succulents or silages, they must gradually increase and have better texture. Early calf eating plant feed can promote rumen development, and can prevent the grazing of contaminated grass. Yak management: In the first few weeks of life, yaks are weak in disease resistance, especially susceptible to dysentery and pneumonia. They should do a good job of breast-feeding hygiene, provide adequate drinking water, keep the cow house clean and dry, use more mat grass, and frequently brush cattle body. Regularly disinfect the cowshed and give calves proper exercise.
