1. Improper colostrum feeding. Colostrum, especially colostrum on the first day of calving, is most important for calf growth. Some farmers lack a reasonable colostrum feeding plan when feeding calves. They do not pay attention to the storage of colostrum, and a large amount of colostrum is discarded.
2. Insufficient supply of regular milk. After 15 days of age, a normal yak weighing more than 55 kilograms, the yak will begin to try to chew hay or silage and foraging intensive feed, resulting in ruminating behavior. However, at this time, the development of the yak forefoot stomach is still incomplete, mainly relying on abomasum digestion. Some dairy farmers only care about their immediate interests and mistakenly believe that calves also eat grass and feed. They will reduce the amount of milk they feed or add water to their milk to increase the amount of forage grass. As a result, calves will grow slowly. The calf volume of the yak with water-adding milk increased, and the proportion of the four stomachs was extremely uneven, forming a hanging belly cow.
3. Transitional milk concentrates are fed with calves. Some dairy farmers, in order to reduce the amount of feed and increase the amount of feed intake, soaked the concentrate in the milk for the calf to feed, so that the milk and the concentrate are easily mixed along the rumen esophagus groove and stomach tube directly Into the wrinkled stomach, causing yak indigestion.
4. Forage feed was late. The emphasis on the supply of milk and concentrates to yak breeders neglects the supply of high quality forage, resulting in a lack of rumen exercise and developmental delay.
5. Feeding time and method are wrong. Some farmers have milked the calves three or five times in the event that abnormal milk cannot be sold. The function of the normal digestive system that has just been established is destroyed, causing diarrhea due to lactose deficiency. In addition, intermittent feeding can easily cause calves to suck.
