There are roughly two ways to feed colostrums to calves: one is to separate them from the cows immediately after they are born, and the other is to keep the calves in their mothers. The cattle live in the enclosures or in the stalls for 3 to 4 days, allowing the calves to use their colostrum on their own. Although the above-mentioned first method uses more manpower, the amount of colostrum fed to yaks can be reasonably controlled, and the management of the mother and son separately for the cow is also very convenient, and it is also convenient for observing the growth status of the calf. Although the second method can save manpower, it does not guarantee that the yak will eat colostrum in time. If the cow's udder is too large, the yak will easily damage the udder when it feeds. Therefore, larger cattle are accustomed to adopting the first method. Please pay attention to the following points when feeding colostrums to newborn calves: 1. In the first hour after the calf is born, sufficient amount of colostrum should be fed in order to ensure that calves have enough antibody protein. Second, the optimum temperature for calves is 15°C. Attention should be paid to the heat preservation, ventilation, and illumination of the yaks, so as to provide yaks with good housing conditions and to gradually cultivate calves' adaptability to the external environment. Third, the temperature of colostrum fed to calves should be controlled at 36°C or more. In order to ensure that the milk temperature can be heated with a hot water bath, direct heating can easily cause the milk to solidify. IV. When feeding colostrum with milk, it should be guided manually. No matter what tools you use to feed your baby, you must not forcibly inject it. Give patience to frail calves when feeding them. Feed them a few more times to ensure that calves have enough colostrum.
