Abstract

The invention discloses a method for positioning a social genetic haplotype site of pig residual feed intake, which is used for identifying a key haplotype of a social genetic effect of the pig residual feed intake by utilizing chip data, whole genome resequencing data, genotype filling, whole genome haplotype construction and a haplotype-based GWAS means. The method has the advantages of accurateidentification and high reliability.

Description

technical field [0001] The invention relates to the field of SNP loci, in particular to a positioning method for social genetic haplotype loci of residual feed intake of pigs. Background technique [0002] Residual feed intake is a very important economic trait that has received particular attention from breeding scientists and pig improvement companies. Residual feed intake traits depend on the expression results of their own genomes (direct genetic effects) on the one hand, and on the expression results of individual genomes in the same group (social genetic effects) on the other hand. The early breeding work mainly focused on the direct genetic effect of pig residual feed intake, but ignored the contribution of social genetic effects to pig residual feed intake. With the continuous advancement of pig genome work and the extensive research and development of molecular genetic markers, genomic selection has become an effective means of selecting important economic traits i...
