Calves are calves born after 3 to 4 months of age or 4 to 6 months of age. Correct breeding of yak is essential for raising the survival rate of yaks.
1. Feed colostrum
The milk secreted by cows 5-7 days after calving is called colostrum. The protein accounted for 18%, which is equivalent to four or five times that of regular milk. Calcium, phosphorus and other minerals are twice as much as regular milk. The content of various vitamins is several times or even ten times that of regular milk. Colostrum also contains lysergic acid and antibodies that kill a variety of pathogenic microorganisms. After entering the calf's stomach, colostrum can stimulate digestive glands to secrete a large amount of digestive enzymes to promote early gastrointestinal function.
In order to make the yaks strong and grow rapidly, the time needed to eat colostrum after birth should be as early as possible, and the amount of food should be better. Generally, the first colostrum should be fed when the calf can stand on its own 30-60 minutes after birth. Do not delay procrastination for no reason, let alone drain the colostrum. The amount of colostrum fed depends on the health of the calf's body weight. About 35kg yak, physical health, the first feeding should try to make them eat enough, generally eat 1-1.5kg. You can feed 1/6-1/7 of your weight later.
Colostrum is fed 5-7 days and fed 4 times a day. The time for feeding colostrum is preferably the same as that of the yak mother's milking time so that it can be fed after squeezing. If the colostrum temperature is low, heat it to 37-38°C and feed it again to avoid indigestion. However, heating should not be too high. If it exceeds 40°C, colostrum will coagulate and will not digest.
2. Feeding regular milk
After calves are fed for 1 week of colostrum, they can be transferred to regular milk. At present, the majority of dairy cows in China are fed with milk 300-400 kg and breastfeeding for 2-3 months. A small number of large or high-yielding herds can be fed 600-800kg and breastfeeding for 3-4 months. The specific feeding is that in the one-month-old stage where regular milk is the main nutrient source, the daily feed volume is about 1/10.2-3 months of age, which is about the calf's weight, that is, the transitional stage. With the increase of forage intake, regular milk The amount of feed decreased from week to week, that is, from feeding gradually to feeding plant feed.
At 1 month of age, the number of breast-feedings is 3 times per day, and then it is reduced to 2 times. Once at 3 months of age, milking is stopped. In order to ensure the normal digestive function of calves, feeding should adhere to regular, quantitative, fixed temperature. In other words, feed your baby on time every day. Don't eat one meal earlier, and feed it in the same amount. Do not eat more than one meal. At the same time, the milk temperature should be maintained at 37-38°C.
3. Early feed to vegetable feed
From 1 week after birth, hay yak can be given quality hay, training its intake, allowing them to chew freely, to prevent calves from eating dirt or grass, and to promote early development of the stomach.
After 10 days of birth, the calf began training to eat concentrated feed. The bran, bean cake, cornmeal, etc. were mixed with a small amount of fish meal, salt, and bone meal to make a dry powder. Feed about 15-25 g per day and put it in the feeding tank. Foraging. After the adjustment, the mixed dry and wet materials are trained to increase palatability and increase feed intake. After 15 days of age, it can be increased to 80-100g, and 250-300g can be eaten at 1 month of age. At 2 months of age, 500g can be eaten daily.
Succulent feeds generally start with 20-30g of chopped carrots or sugar beets in the mixed concentrate starting 20 days after birth. By the age of 2 months, the daily feed amount will reach 1-1.5kg, and it can be increased to 2-3kg at 3 months of age. To promote the development of digestive organs.
Silage can be fed from the age of 2 months. The amount of silage can be gradually increased from less than 3 months to 1.5-2 kg at 3 months and to 4-5 kg ​​at 4-6 months.
4. Early weaning
The so-called early weaning, that is, the past 5-6 months of breast-feeding, consumption of milk 800-1200kg, reduced to 2-3 months, consumption of milk 300-400kg, to prepare nutritious, high precision artificial milk or milk replacer To cultivate yaks. This can save a lot of "feed milk" and reduce production costs.
The key to the success of early weaning is to formulate a good weaning plan, with the exception of early feeding of hay.
1) The yak is fed with colostrum within 1 week of birth and is fed 3 times a day, 2 kg each time.
2) Feed regular milk 8-20 days old, 2 times a day, 2kg each time, and train to eat milk replacer and quality hay.
3) Feed regular milk at the age of 21-60 days, feed 2 times a day, feed 2 kg every day for the first 35 days, and feed 1 kg each time for 5 days. The daily feeding amount of milk substitute gradually increased to 1.2kg. At the same time, training to eat silage.
4) 1-180 days of age, milk replacer gradually increased from 1.2kg to 3.4kg per day. Casually eat hay and silage.
5) Milk replacer formula: bean cake 40%, wheat bran 20-10%, corn flour 40-25%, sorghum flour 20-10%, additive 1%, salt 1%, bone meal 1%.
5. Provide sufficient drinking water
One week after birth, start replenishing water daily or add appropriate amount of milk to the water to lure it to drink. The tap water must be boiled, cooled to 37-38 °C, and then fed separately after feeding. After 10-15 days, drink cold water. In the warm season, a sink is set up on the playground to hold clean water for the yaks to drink freely.
