Calves generally refer to calves before 6 months of age. Reserve cows generally refer to cows from 6 months of age until the first child is born. It is customary to refer to 6-12 months old backed cows as bred cows, and 12-month-old cows as young cows. In the calf stage, the following management work should mainly be done. 1. Feed colostrum. Colostrum is rich in nutrients, and contains lysozyme and antibody proteins. Generally, calves can feed colostrum 2 hours after birth. Colostrum should be fed immediately, avoiding deterioration or temperature reduction. After calves are fed 5-7 days of colostrum, they are fed with regular milk until 60 days of age. The amount of milk to be fed daily is 8 kg for 1-7 days, 3 times for feeding; 6 kg for 8-35 days, 2 times for feeding; 5 kg for 36-50 days, 2 times for feeding; 51-56 days The age of 4 kg, 2 times feeding; 57-60 days of age 3 kg, 1 night feeding. 2, tune yak. For newborn yaks who do not feed their milk, they can be sucked into the calf's mouth with their hands, repeatedly; often brush calves; keepers often come into contact with calves, to avoid cows being afraid of people and being able Tuning cattle positioning, recognizing beds, milking stations, etc. 3, weaning feed. The weaning time is generally controlled at 70-90 days of age. From the 7th day after the calf's birth, besides feeding cow's milk, it should be fed with food, hay and water, as well as a small amount of grass. The starter diet is formulated with corn, barley, (mature) soybean meal, a small amount of peanut meal, fish meal, calcium hydrogen phosphate, and additives. The crude protein content is higher than 21%, crude fiber is less than 15%, and crude fat is about 8%. Into pellets. The amount of starter feed is increased as needed, and the calf can be weaned when it can eat 1 kg of starter feed per day. After weaning, continue feeding the food until 4 months of age, and feed 1.8-2.5 kg of concentrate daily to reduce weaning stress. After 4 months of age, it can be changed into a bred cow or young cattle concentrate. Breeding cattle is in the period of the most vigorous growth and development. The characteristics of feeding are mainly green and rough feeds, such as a large supply of green and green juice, yew grass, alfalfa hay, silage corn, and appropriate supplements. The amount of concentrate supplemented daily is about 3 kg before 1 year old. After the cow is 1 year old, the estrus performance should be observed. Generally, artificial insemination and breeding are performed when the cow weighs 350 kg (15-18 months). The feed of cattle after pregnancy should be appropriately increased. According to the quality of green roughage, the daily amount of concentrate can be 3-4 kg. For young cattle that are not poorly fed but not yet pregnant, the supply of concentrates can be reduced to prevent deposition of fats in the uterus and ovaries, affecting developmental conception; for the thin young cattle, the causes must be ascertained; for malnourished cattle, the increase may be appropriate. Fine material supply, and with a certain amount of quality roughage. Practice has proved that breast massage on young cattle can promote breast development, which will facilitate milk production after delivery. Normally, the self-breeding cow begins breast massage after being conceived by using a warm wet towel to massage the bottom ditch and both sides of the breast. Massage at least once a day, preferably in the morning and afternoon, massage once every 1-3 minutes, 1 month before the expected date of delivery. (Source: Farmers get rich)
