Problems solved by technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, eating high-grade beef has become a consumption fashion of modern people. The market demand for high-grade beef is growing rapidly. There are no specialized high-grade beef cattle breeds in China, and there is a serious shortage of high-grade beef. At present, my country's medium and high-grade beef mainly depends on imports, and the price of imported beef is relatively high, which is difficult for ordinary consumers to accept

Embodiment 1

[0011] The new four-way hybrid synthetic beef cattle strain of the present invention is bred according to the following steps: (1) crossbreeding German yellow cattle and Nanyang yellow cattle, and then using Red Angus cattle as the second male parent to produce Red Angus cattle, German cattle Yellow cattle and Nanyang yellow cattle are three-way crossbred cattle, which are selected and bred to form a paternal group; (2) Simmental and Nanyang yellow cattle are crossbred at the same time, and Red Angus cattle are also used as the second male parent to produce Red Angus cattle , Simmental, and Nanyang yellow cattle three-way hybrid cattle, which are selected and cultivated to form a female line group; (3) use the male line obtained in step (1) to cross the female line obtained in step (2) to form a synthetic line; (4) The synthetic line obtained in the step (3) can be selected and crossed and fixed, and a new four-way hybrid synthetic beef cattle line can be bred. Among them, the...

Embodiment 2

[0013] The new four-way hybrid synthetic beef cattle strain of the present invention can also be cultivated according to the following steps: (1) crossbreeding German yellow cattle and Nanyang yellow cattle, and then using red Angus cattle as the second male parent to produce red Angus cattle , German Yellow Cattle, and Nanyang Yellow Cattle are selected and bred to form a paternal group; (2) Simmental and Nanyang Yellow Cattle are crossbred at the same time, and Red Angus cattle are also used as the second male parent to produce Hongan Ges, Simmental, and Nanyang yellow cattle three-way hybrid cattle are selected and cultivated to form a female line group; (3) the male line obtained in step (1) is crossed with the female line obtained in step (2) to synthesize a new line of cattle; ( 4) Use the synthetic line bred in step (3) as the female parent, and then use the red Angus bull as the male parent, perform stepwise hybridization once, and after selection and fixation, a new fo...

Abstract

A quadruplex hybridization method for culturing new variety of meat ox includes such steps as the ternary hybridization between German ox, Nanyang ox and Hongangesi ox as the secondary male parent, choosing male group, the ternary hybridization between Ximentaer ox, Nanyang ox and Hongangesi ox as the secondary male parent, choosing female group, and the hybridization between said made group and female group, and preferable culture.

Description

technical field [0001] The invention relates to a method for cultivating cattle, in particular to a method for cultivating new strains of beef cattle synthesized by four-way hybridization. Background technique [0002] With the improvement of people's living standards and the enhancement of health awareness, eating high-grade beef has become a consumption fashion of modern people. The market demand for high-grade beef is growing rapidly. There are no specialized high-grade beef cattle breeds in China, and there is a serious shortage of high-grade beef. At present, my country's medium and high-grade beef mainly depends on imports, and the price of imported beef is relatively high, which is difficult for ordinary consumers to accept. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating a new line of synthetic beef cattle by four-way hybridization. [0004] In order to achieve the above object, the technical solution of...
