Example Embodiment

[0010] Example 1

[0011] The new quaternary hybrid synthetic beef cattle line of the present invention is bred according to the following steps: (1) Cross between German yellow cattle and Nanyang yellow cattle, and then use red Angus cattle as the second male parent to produce red Angus cattle, German cattle Yellow cattle and Nanyang yellow cattle ternary hybrid cattle are selected and cultivated to form a sire line group; (2) Simmental and Nanyang yellow cattle are crossed at the same time, and Red Angus cattle are also used as the second male parent to produce Red Angus. , Simmental, Nanyang yellow cattle ternary hybrid cattle, selected and cultivated to form a maternal population; (3) Cross the sire line obtained in step (1) with the maternal line obtained in step (2) to form a synthetic line; (4) The synthetic line obtained in step (3) is selected and cross-crossed and fixed, and a new quaternary hybrid synthetic beef cattle line can be cultivated. Among them, the pedigree of...

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...
