In the swine industry, growth related traits are important economic traits directly linked to profitability. Representative growth traits include daily gain, back fat thickness, and carcass weight. This study was conducted to search for positional candidate genes associated with the carcass weight through a genome-wide association study(GWAS) using suggestive levels of statistical thresholds in pigs. As a result of the genome-wide analysis of the associations with carcass weight, the single nucleotide polymorphism(SNP) markers with suggestive significance were identified in 1 SNP marker on chromosome 2(ALGA0015365) and 1 SNP marker on chromosome 4(ALGA0023678). We could select positional 2 candidate genes, located close to the SNP markers with suggestive significance levels. The SNP markers in adjacent to the 2 genes(LOC100519538, LOC100737583) may provide basic data regarding the marker-assisted selection for the carcass weight trait in pigs.
