Problems solved by technology

If the calf only gets 200 kg of whole milk within 6 months of age, the development of reproductive organs and sexual maturity will be slow, the first insemination will be delayed for 2 to 3 months, and the conception rate will be low, which means that the calf under poor feeding Calves not only grow slowly, have low live weight and high mortality, but also seriously affect the reproduction of adults
Moreover, in the first cold season after birth, yak calves lose weight, stagnate in growth and development, and even die, which seriously restricts the breeding process of yaks.

Abstract

The invention discloses a special milk replacer for a yak calf and a preparation method of the milk replacer. The special milk replacer comprises the following components in weight part: 26-32 parts of whole milk powder, 1-15 parts of puffed peas, 25-45 parts of soy protein concentrate, 14-16 parts of vegetable oil, 0.3-1 part of a microelement additive and 0-0.5 part of probiotics. Through the adoption of the technical scheme of the invention, the yak calf is enabled to safely live through the first cold season, the nutrition supply for the yak calf is also guaranteed, so that the rate of survival and the growth development of the yak calf are improved, and meanwhile, the slaughtering rate of the calves in the current year is increased.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to a special milk substitute for yak calves and a preparation method thereof. Background technique [0002] The yak is a long-haired bovine animal that lives on the Qinghai-Tibet Plateau. It is the mammal that lives at the highest altitude in the world. It is mainly produced in areas above 3,000 meters above sea level on the Qinghai-Tibet Plateau in my country. At present, yaks in most areas only rely on natural grass pastures to obtain the nutrients they need to maintain life, grow and reproduce. Even in the winter and spring cold season, when the natural pasture grass is withered and the forage grass is lacking, supplementary feeding will not be given except for a small number of young yaks and female yaks who are weak and difficult to survive spring. Yaks suffer from malnutrition in winter and spring, and calves have low birth weight, low survival rate and slow growth rat...
