Method for cultivating novel beef cattle strain

Abstract

The invention discloses a method for cultivating a novel beef cattle strain, which comprises the following steps: (1) hybridizing a Jiaxian red cattle with an Australia wagyu cattle and carrying out three way cross by using a black angus cattle as a male parent to produce a there way cross cattle of the black angus cattle, Australia wagyu cattle and Jiaxian red cattle, forming a female group afterpreference selection and cultivation; (2) meanwhile, hybridizing the black angus cattle and the Jiaxian red cattle to produce a two way cross cattle of the black angus cattle and Jiaxian red cattle,and forming a male parent group after preference selection and cultivation; (3) hybridizing the female line obtained in step (1) with the parent line obtained in step (2) to synthesize the novel strain; (4) carrying out crossing and fixing on the synthetic strain cultivated in step (3) so as to breed the novel three way cross beef cattle strain. According to the invention, on the basis of the excellent characters of the Jiaxian red cattle, excellent advantages of the Australia wagyu cattle and black angus cattle are absorbed through the synthetic breeding.

Description

technical field [0001] The invention relates to a method for cultivating cattle, in particular to a method for cultivating a new strain of beef cattle. Background technique [0002] my country's cattle industry has a long history, but for a long time cattle have been mainly used for labor. With the improvement of people's living standards and the enhancement of health care awareness, eating high-grade beef has become a consumption fashion for modern people. The market demand for high-grade beef China has no specialized high-end beef cattle breeds, and there is a serious shortage of medium and high-grade beef. It mainly relies on imports, and the price of imported beef is relatively high, which is difficult for ordinary consumers to accept. The binary hybridization of excellent beef cattle breeds introduced in my country and local breeds has improved the carcass meat yield, but there are deficiencies in the production of high-grade beef.
