Problems solved by technology

[0008] (2) The problem of improved varieties is prominent
Although some areas have also developed some specialized large-scale beef cattle fattening farms and large-scale beef cattle fattening professional households, the number of slaughtered cattle they slaughtered is very limited, accounting for a small proportion of the total slaughtered cattle
[0010] (4) Low degree of industrialization
[0014] Disadvantages of the existing high-grade beef cattle breeding route: Due to the good market prospects and large profit margins of high-grade beef, many production enterprises only think that high-grade beef cattle can be bred by cross-breeding and improving Japanese Wagyu cattle, but they do not consider that after cross-breeding and improvement, they will not reach production demand, causing great economic loss and time

Embodiment

[0026] Such as figure 1 The new route for high-grade beef cattle breeding shown specifically includes the following steps:

[0027] (1) Select excellent Qinchuan cows, mainly considering reproductive performance, limb structure, coat color, appearance, etc., for selection;

[0028] (2) Japanese Wagyu and Black Angus jelly selection, choose the best, especially Japanese Wagyu and Black Angus that can reflect the marble pattern;

[0029] (3) After the Japanese Wagyu and Qinchuan cattle are crossed, the F1 generation is produced, and excellent cows are selected from them, especially in terms of body shape;

[0030] (4) Use black Angus hybrid F1 cows to produce F2 generation, and then select excellent cows from the F2 generation to cross with Japanese Wagyu to produce F3 generation, select excellent cows and bulls for cross selection, and then Fixed, controlled marbling genes, to achieve the ultimate goal, to breed new varieties.

[0031] In the embodiment of the present invent...

Abstract

The invention relates to a new breeding path for high-grade beef cattle breeding, and belongs to the technical field of animal breeding. According to the technical scheme, the new path is designed from the perspective of animal genetic breeding, and the new path is mainly characterized in that according to hybridization improvement between two breeds or more breeds, and the fact that whether heterosis is fully expressed in the genetic aspect, multiple-effect gene stacking of marbling is controlled, and therefore genes of the marbling are controlled to be continuously stabilized in the descendant, and the new high-grade beef cattle breed is formed. Relatively speaking, the marbling distribution is good, the grade of the marbling obtained after slaughtering is improved, and the product yield of high-grade beef cattle breeds is continuously improved. The method can be used for high-grade beef cattle new breed breeding with the stable production performance, and high-grade beef cattle can be produced in a large-scale mode.

Description

technical field [0001] The invention relates to a new breeding route for high-grade beef cattle, which belongs to the technical field of animal breeding. Background technique [0002] Since the reform and opening up, my country's animal husbandry has maintained a high speed of development and achieved continuous growth. my country has become a veritable animal husbandry production country. Among them, the beef cattle industry has also developed greatly, and the number of cattle slaughtered and the output of beef have maintained a momentum of increasing year by year. In 1980, 3.322 million cattle were slaughtered in my country, and the output was only 269,000 tons; in 2006, 56.029 million cattle were slaughtered, and the beef output reached 7.5 million tons, 16.9 times and 27.9 times that of 1980, respectively. [0003] According to the data from the National Bureau of Statistics, in the first half of 2007, my country's urban residents purchased 1.35 kilograms of beef per ca...
