(I) Feeding San Ding 1. timing. Regular feeding is a good dietary reflex for calves. Feeding should be done for a fixed number of times to increase appetite and digestion in calves. In the first 2 weeks, you should feed less frequently, feed 4 times daily, feed 3 times on 3-5 weeks, and feed 2 times daily after 6 weeks. Irregular diet will lead to the secretion of digestive juice and gastrointestinal disorders in yak, which can lead to various diseases and affect the normal growth and development of calves. 2. Quantitative. Food should be reasonably fed according to the feeding program standard. For the first two weeks of calf, calves should be half-starved and must not be over-eating, otherwise they can easily cause calf squatting. The daily feeding of these two weeks is about one-tenth of the body weight, so that it maintains a strong appetite without affecting health. On 3-4 Sundays, the amount of milk fed was 1/8 of its body weight, 5-6 weeks of age was 1/9 of its body weight, and after 7 weeks of age it was 1/10 of body weight or gradually weaned. Each feeding should be 1/4-1/2 clean warm water in fresh milk. Without diluting the water, the milk is not fully mixed in the oral cavity in the digestive juice, and the acne can be solidified into a hard and difficult to digest agglomerate. If the agglomeration is too hard, the pyloric plug can often be caused and the food cannot be discharged in the stomach. Will wrinkle the stomach and die. 3. Fixed temperature. Maintaining a constant milk temperature is an important principle for feeding milk calves. If the diet is too cold, it will lead to gastrointestinal motility and accelerate diarrhea. If the diet is too hot, it is not good. A high-temperature diet can make the digestive tract mucous membrane congestion and inflammation in yak. Causes enteritis. It is generally best to stay at 38-40 degrees.
