SNP loci related to live weight before slaughter in Chinese Wagyu cattle and their application

Abstract

The invention provides the SNP site on the No. 14 chromosome of cattle related to the live weight of Chinese Wagyu cattle, and the SNP marker site is the 25284162nd nucleotide site on the No. 14 chromosome of the international bovine reference genome UMD3.1 version , the base at this site is A or C. By optimizing the dominant allele of the SNP, the invention can increase the frequency of the dominant allele generation by generation, increase the live weight of Chinese Wagyu cattle before slaughter, accelerate the progress of cattle genetic improvement, and effectively improve the economic benefits of beef cattle breeding.

Description

technical field [0001] The invention relates to the analysis of Chinese Wagyu chromosomal loci and related traits, in particular to the SNP loci on the Chinese Wagyu chromosomal related to pre-mortem live weight and the application thereof. Background technique [0002] my country is the world's largest producer of animal husbandry, and the output value of the beef cattle industry is close to 200 billion yuan, accounting for 25% of the output value of animal husbandry. 10% of the world's cattle are raised in my country, the number of slaughtered heads ranks first in the world, and the output of beef ranks third in the world. However, the average carcass weight of beef cattle does not exceed 154 kg, which is only close to half of that of developed countries in Europe and the United States. This not only limits the long-term stable development of my country's beef cattle industry, but is also a risk factor for the sustainable development of the beef cattle industry such as int...

However, the average carcass weight of beef cattle does not exceed 154 kg, which is only close to half of that of developed countries in Europe and the United States. This not only limits the long-term stable development of my country's beef cattle industry, but is also a risk factor for the sustainable development of the beef cattle industry such as international market competitiveness and epidemic diseases.
