The cultivation of yaks is one of the most important aspects of cattle breeding. Therefore, the following aspects should be grasped in the breeding management to ensure the health and normal growth and development of yak. Delivery of yak: When a cow is delivered, it is necessary to check whether the position of the fetus is normal or not. When the fetal position is normal, try to allow it to produce freely, without forcibly dragging. After the yak is born, the mucus and mouth mucus should be removed immediately and the calf should breathe as soon as possible, and lightly press the lungs to prevent mucus from entering the trachea. Next, the yak's umbilical cord was cut at a distance of 10 cm from the abdomen and soaked in 5% iodine for 1 minute to 2 minutes for disinfection. The fetal fluid in other parts of the yak body is best to clean the cows. Feed colostrum as soon as possible: Colostrum plays a key role in enhancing the disease resistance of calves. In general, calves can drink up to 6% of colostrum in 1 hour to 2 hours postpartum. The second feeding should be 6 hours to 9 hours after birth. Cooling colostrum can be heated with hot water in the bath. The open flame can destroy its nutrient components. Reasonably feeding yak: 1. The milk fed to yak must be healthy cow's milk, avoid feeding milk that is inferior or deteriorating, and do not feed cows suffering from mastitis. 2, quantitative determination of 8% -10% of body weight, breast-feeding period of 2 months, the first 7 days 5 kg, 6 days - 20 days 6 kg, 31 days - 40 days 5 kg, 41 days - 50 days 4.5 kg , 51 days - 60 days 3.7 kilograms, full-time feeding 300 kilograms. 3, regular fixed feeding time, strict control, not too early or too late. 4, constant temperature refers to the temperature of feeding milk, generally summer grasp 34 °C -36 °C; winter 36 °C -38 °C. Feeding of feed: Starting from the first week after birth, add hay to the straw stand in the calf field and allow it to be chewed and practice feeding. Ten days after birth, calves can be trained to eat concentrates. At the beginning, the fine material can be applied to the yak's mouth, nose or put in the milk barrel 10g-20g (1 two = 50g), allowing them to freely forage. After a few days it can be increased to 80 g - 100 g. At the age of 1 month, 250 g to 300 g were fed, and at the age of 2 months, about 500 g was fed. The training of concentrate feed intake is the key to early weaning, and yak feed should pay attention to the appropriate amount of feed. One week after the yak is born, it can be induced to drink water. Initially, a small amount of lotion can be added to the water to induce it to drink. Within 30 days, water is warmed at 36°C to 37°C. After 10 days, normal temperature water is given, but the water temperature is generally not lower than 15°C. Weaning Techniques: The calf's lactation is generally two months and the baby is fed 3 times a day. The well-developed yak can be fed twice a day for 40 days, feeding 4 kg to 4.5 kg, changing to a daily feed for 50 days, and feeding 3 kg to 3.5 kg. Calves are weaned at any time and will lose weight in the first few days, which is normal. The calf should remain in a separate cage 10 days after weaning until the calf does not have a milk requirement.
