Early feed intake. The starter diet, also known as calf milk replacer, is formulated with concentrates based on the nutritional needs of calves. Its role is to promote the transition from calf-based nutrition to fully-feed botanical fodder. The feed is in the form of powder or granules, and is used by the yak for the second week after birth. Under low-fat feeding conditions, calf intake gradually increases, and it gradually becomes customary to concentrate feed and roughage, if The calf's feeding barrier is added to the animal's trough (ie it can imitate the intake of the cow and prevent the calf from eating the calf). The calf's intake of 30 days old can reach more than 300 g.
Yak feeding. 1. Feed concentrates. When the yak is supplemented with concentrate at the age of 10 days to 15 days, it is applied to the nose and lips with a small amount of fine material, or sprinkled on the milk bucket for a foraging purpose. This causes the yak to form feeds. The habit of concentrating on raw materials, 1 month of age, yak feed intake 250 grams -300 grams, 2 months of age 500 grams -700 grams. 2. Feed hay. From the first week of age, high-quality hay (such as legumes, hay, etc.) is added to the grass in the cowshed to train the calves to feed freely, promote the growth of the tumor's reticulum and prevent foreign food from being eaten. 3. Feed the green juicy feed. Juicy green feeds such as carrots, beets, etc., calves start feeding at 20 days of age to promote the development of digestive organs. Feeding 20 grams daily will increase to 1 kg to 1.5 kg at 2 months of age and 2 kg to 3 kg at 3 months of age. Silage can be fed at the age of 2 months, 100 grams to 150 grams per day, 1.5 kg to 2 kg at 3 months of age, and 4 kg to 5 kg at 4 months to 6 months of age. 4. Feeding by column. In the cowhouse, a small bullpen that can only be freely accessed by the calf, a built-in fine feed for the calf, and a short-cut, high-quality group feed (such as alfalfa, red bean grass, Dayan, etc.) can be added. Cattle gain weight. After 40 days of supplemental feeding, 60-day-old yaks can weigh 65 kg-75 kg, and the daily intake of concentrate feed can reach about 0.7 kg. Continue to 90 days of age, weight can reach 80 kg -90 kg, daily intake of 1 kg -1.5 kg.
Weaning standards were implemented. When the daily feed intake of concentrated feed is more than 1 kg, it is basically 3 months after birth. The calf is moved into a weaning cowshed, which can be started every other day, then breast milk is eaten once every two days, and is completely exfoliated in about 10 days.
