SNP locus related to live weight of Chinese wagyu before slaughtering and application

Abstract

The invention provides an SNP locus related to the live weight of Chinese wagyu before slaughtering and located on a chromosome 14 of cattle. The locus of an SNP marker is the 25284162nd nucleotide locus on the chromosome 14 of an international cattle reference genome UMD3.1 version, and the base of the locus is A or C. By optimizing dominant allele of the SNP, the frequency of the dominant allelecan be increased generation by generation, the live weight of the Chinese wagyu before slaughtering is increased, and the genetic improvement progress of the cattle is accelerated, so that the economic benefit of beef breeding is effectively improved.

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...
