Embodiment 1

[0012] Embodiment 1: The new line of three-way cross-synthetic beef cattle of the present invention is bred according to the following steps: (1) cross-breeding Black Angus cattle and Jiaxian Red cattle, and then carrying out three-way cross-breeding with Australian Wagyu as the second male parent, Black Angus cattle, Jiaxian Red Cattle, and Australian Wagyu three-way hybrid cattle were produced, which were selected and bred to form a matrilineal group; (2) Australian Wagyu and Jiaxian Red Cattle were crossbred at the same time to produce Australian Wagyu and Jiaxian Red Cattle. Yuan hybrid cattle, after selection and breeding, form a male group; (3) use the female line obtained in step (1) to cross with the male line obtained in step (2) to form a synthetic line; (4) combine the synthetic line obtained in step (3) After selection and fixation, a new three-way crossbred beef cattle line can be bred. Among them, 50% of the synthetic new strains are from Australian Wagyu cattle,...

Abstract

The invention discloses a method for cultivating a new strain of Central Plains Black Cattle synthesized by three-way hybridization, which is cultivated according to the following steps: (1) crossbreeding Black Angus Cattle and Jiaxian Red Cattle, and then using Australian Wagyu Cattle as the second male parent Carry out three-way hybridization to produce three-way hybrid cattle of Australian Wagyu, Black Angus, and Jiaxian Red Cattle, which are selected and bred to form a matrilineal group; , Jiaxian Red Cattle Binary Hybrid Cattle, which are selected and cultivated to form a paternal group; (3) crossbreeding the female line obtained in step (1) with the male line obtained in step (2) to form a synthetic line; (4) combining step (3) ) obtained synthetic lines can be selected and fixed to breed new high-grade beef cattle lines. The invention absorbs the excellent characteristics of the parents of Australian Wagyu and Black Angus cattle through synthetic breeding on the basis of the excellent traits of Jiaxian Red Cattle.

Description

technical field [0001] The invention relates to a method for cultivating cattle, in particular to a method for cultivating a new strain of Zhongyuan Black cattle synthesized by three-way hybridization. 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-g...
