Artificial breastfeeding, mother and son separation, and self-education of calves in pots, buckets, or pots, is one of today's best breeder calves, speeding herd turnover, and improving the overall efficiency of cattle (especially dairy cows). advanced technology.
For yak artificial breastfeeding, the first step is to feed the colostrum in time (the milk secreted by the cow within 7 days after birth). When the calf has been able to stand, it will be fed out by the colostrum for 5 to 7 days (after changing to regular milk). The first meal of colostrum is not limited, so it is appropriate to eat. After that, the daily feed is about 1/6 of its body weight, which is higher than that of normal milk. The number of daily feedings is not less than 3 times (2 times for regular milk). . Extrusion of colostrum (as well as regular milk) should be immediately fed. If the milk temperature drops, the water bath should be heated to 35-38°C. If the temperature is too high, the milk will freeze and the calf will refuse to feed. If the temperature is too low, it will cause the calf to squat. In the event of cows suffering from illness or death after birth, cows colostrum from the same period of delivery, or frozen calves and extra colostrum fed to the calf during the same period are used to feed calves.
Artificial nursing, for yak who will be feeding milk, as long as the mouth into the milk feeding container can freely eat milk. However, for small cockroaches that do not suck milk, they should generally insert the washed index finger and middle finger into the mouth of the cow. When the cock sucks a finger, it slowly introduces the mouth of the cow into the pot or barrel that contains the milk. Inhale milk as you suck your fingers. After repeated training, yaks are accustomed to feeding directly in feeding containers. Some fields are divided into two steps. The first step is to use a milk pot with a pacifier to feed the baby. When the calf is 3 to 4 weeks old and then use a milk bottle to feed it, this method is fine, but it is necessary to prevent it from being stopped. After using the pacifier, the yak loses its conditioned reflex on the nipple and does not feed on it. Therefore, it is advisable that the pacifier be used within a period of 3 days. When using the milk pot, you should use a knife at the top of the teat to cut a "10"-shaped crack, so that the yak must suck hard when sucking, and by means of slow sucking action, the esophageal furrow is closed into a tube, which is conducive to saliva The mixed milk flows into the abomasum and digests along the furrows. If the teat is cut into a round hole or if the tear is too large, then the sucking of the milk is effortless and the drinking of the milk is too quick, and the troubles are endless. In addition, when barrels are fed after 3 to 4 weeks of age, the yak's mouth must be placed on top of the hand to control the speed of milking, so that the time for feeding each cow is no less than two minutes, and the adverse consequences of overeating the baby can be prevented.
Artificial nursing, the hygiene of milk and feeding utensils, the speed of breast milk delivery, milk temperature, etc. are all more difficult to master than breast-feeding mothers. Therefore, digestive tract diseases often occur. Therefore, we must strictly follow the scientific procedures for feeding and protection. For general dyspepsia, it is only necessary to reduce the amount of feeding by 20 to 40% and add 30% warm water to the milk.
The amount of breastfeeding on artificial nursing days is as follows.
Dairy cows (for 60 days early weaning as an example): 1 to 7 days 8 kg, 3 times feeding; 8 to 35 days 6 kg, 2 feedings; 36 to 50 days 5 kg, 2 feedings; 51 to 56 Day 4 kg, 2 times feeding; 57-60 days 3 kg, fed once at night. The 60-day total feeding amount is 300-320 kg.
Beef cattle: 1 to 2 weeks old, small cattle 3.7 to 5.1 kilograms, large cattle 4.5 to 6.5 kilograms; 3 to 4 weeks old 4.2 to 6 and 5.7 to 8.1 kilograms; 5 to 6 weeks of age 4.4 to 6 kilograms; 7 to 9 weeks Age 3.6 ~ 4.8 kg; 10 ~ 13 weeks old 2.6 ~ 3.5 kg; 14 weeks later 1.5 ~ 2.1 kg. The total milk consumption is 400-540 kg.
