Abstract

The invention provides a breeding method for heat-resisting beef cattle, which comprises the following steps: mating a Brahman bull with a mourn catalo cow to obtain a first generation cattle I; mating a Brahman-mourn catalo bull with a mourn catalo cow to obtain a first generation cattle II; mating the first generation cattle I with the first generation cattle II to obtain a second generation cattle; mating like to like or selecting excellent individuals from the second generation cattle to mate with a Brahman-mourn catalo to born a third generation cattle which is the heat-resisting beef cattle. The beef cattle obtained according to the invention has high breeding survival rate, fast growth, early maturity, good meat production performance, even muscular fat distribution, tender meat, good taste, tick and heat resistance, and wide adaptability.

Description

technical field [0001] The invention relates to a method for animal breeding, in particular to a method for breeding heat-resistant beef cattle. Background technique [0002] There are many excellent beef cattle breeds in the world. Since they are all bred under different environmental conditions, their production performance and environmental requirements are also different. For example, Simmental cattle, Hereford cattle, Angus cattle, Brahman cattle, Shahihua cattle, shorthorn cattle, Murray gray cattle and other beef cattle breeds have been introduced from abroad. The rate is not high, the growth rate is not fast, and it is difficult to adapt to tropical and subtropical climates. Contents of the invention [0003] The object of the present invention is to provide a method for breeding heat-resistant beef cattle. The breeding base group used includes Pomoyun hybrid cattle (BMY), Pomo hybrid cattle (BY), Moyun hybrid cattle (MY), and Pomo hybrid cattle. (BM) and Brahman...
