1. Feed colostrum as early as possible
The milk produced 5 to 7 days after delivery of the cow is called colostrum. The sooner you drink colostrum, the better, that is, within 1 to 1.5 hours after the cow has given birth. For the first feeding, the amount of feeding for a healthy yak is 2 kg and the infirm is 0.75 to 1 kg. The first colostrum dose should not be too large to prevent digestive disorders. A few days later, the yak can calculate the amount of colostrum by 1/5 of the body weight every day and feed it 2 or 3 times a day. The amount of each feeding should be approximately the same.
After the colostrum has been extruded, it should be fed in time. If the temperature of the colostrum drops, it can be fed when it is heated to 35°C to 38°C. Colostrum is 4 to 7 days. After that, they were transferred to yak herd and fed with mixed milk. If a cow dies after childbirth, colostrum from Other healthy cows delivered during the same period can be fed. Can also be fed regular milk, but every day need to make up 20 ml of cod liver oil or other preparations containing vitamin A, another 50 grams of castor oil to play a role in light laxation. Can also be fed artificial colostrum, the formula is: 2 to 3 fresh eggs, salt 9 to 10 grams, 15 grams of fresh cod liver oil. Add 1 liter of clean, boiled and cooled to 40 °C ~ 50 °C water, mix well, according to yak cattle fed 8 to 10 ml per kilogram of body weight.
2. Remove mucus
After the yak is born, the mucus in the mouth and nostrils should be eliminated first so as not to interfere with breathing and cause yak suffocation. If the yak has inhaled mucus to affect breathing, raise the hindlimb so that the yak head down, beat or lightly oppress the chest and abdomen, shake the body, so that inhaled mucus and amniotic fluid discharge, and clean the mouth and nostrils with a clean gauze. Followed by the use of hay or dry rags wipe the mucus on the bovine body so as to avoid calves cold. In severe cases, the hose can be inserted into the nasal cavity and trachea and the mucus and amniotic fluid can be aspirated.
3 off the umbilical cord
After wiping the mucus, the umbilical cord tends to tear naturally. If you do not cut the umbilical cord, you can cut the umbilical cord with sterile scissors 10 to 12 cm away from the yak's abdomen, then squeeze out the mucus from the umbilical cord and disinfect it with iodine to prevent omphalitis. One week after the umbilical cord was broken, the umbilical cord was dry and shedding.
