SNP loci related to front hoof weight on chromosome 6 of meat Simmental cattle and its application

Abstract

The invention provides an SNP site related to the forehoof weight on chromosome 6 of a simmental cattle for beef, and application of the SNP site. The SNP marked site is a 38815034 nucleotide siteon the chromosome 6 of an international cattle reference genome UMD3.1 version, and a basic group of the site is A or G. By optimizing the advantage allele of SNP, the frequency of the advantage allele can be increased by generations, the forehoof weight of the simmental cattle for the beef is increased, the development of cattle genetic improvement is accelerated, and thus the economic benefitsof beef cattle breeding are effectively increased.

Description

technical field [0001] The invention relates to a SNP site related to front hoof weight on chromosome 6 of meat Simmental cattle and its application. Background technique [0002] Meat Simmental is the most popular breed of cattle hybrids in China. It has the characteristics of fast growth and high meat production rate, so it is often used as the terminal male parent in breeding production. The front hoof weight refers to the weight of the front hoof. Compared with the rear hoof, the front hoof contains more lean meat, so it is more popular in the market. At present, the breeding of Simmental cattle for meat mainly focuses on improving the growth traits such as meat yield and growth speed, while less attention is paid to the selection and breeding of hoof weight. In addition, hoof weight is a quantitative trait controlled by multiple genes, and there are a large number of quantitative trait loci (quantitative trait loci, QTLs) related to it on the genome. Therefore, it is ...
