Yak high-yield breeding method

Abstract

The invention belongs to the technical field of livestock breeding, and particularly relates to a yak high-yield breeding method. Comprising the following steps: (1) from the beginning of April every year, grazing cows and bulls in groups; from November, the cows and the bulls are grouped and then are fed with concentrated feed in the farm; (2) carrying out cow mating and breeding tasks in the next February, wherein the cows complete breeding from the middle ten days of October to November in the gestation period; (3) feeding the bred calves in a farm for 90-100 days and then entering a growth period, and performing grazing and supplementary feeding breeding in the growth period; the cattle are slaughtered in February of the next year after the breeding period, and the cattle are bred in groups after being slaughtered. The yak breeding technology has the following beneficial effects that the yak breeding technology is used for farrowing in winter, calves have few diseases, feeding is convenient, the survival rate of the calves is high, the breeding efficiency is improved, the number of the yaks is increased, and the production performance of the yaks is improved; within 155 days in winter and spring of one year, a stable pasture breeding system is formed, and the body condition of the yaks is kept.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a high-yield breeding method for yaks. Background technique [0002] The yak is a rare animal species that can adapt to the alpine climate and has continued to this day. It is a rare animal resource with a limited range of domestic animals in the world. Today, yaks still belong to the original closed cattle species with low growth performance. In the alpine region, the grass growth cycle period is long, and the dry grass period is long, resulting in slow growth of yaks. The body condition and weight gain of yaks show a vicious circle of "strong in summer, fat in autumn, thin in winter, and dead in spring" with the growth season of forage, and the population reproduction rate is low. The turnover is slow and the commodity rate of the products is not high. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies...
