Abstract Text:

A genome wide association analysis for two carcass traits, hind shank and thick flank, in Simmental cattle was carried out using BovineHD chip included 676,854 SNP on 29 BTA. Two different models applied to association test, general linear model (GLM) and compressed mixed linear model (CMLM). At conservative Bonferroni-corrected, the majority of significant SNPs heavily located around 38 to 40Mb on BTA6. Of these SNPs,there were 85 and 38 SNPs significantly associated with the traits thick flank and hind shank  respectively, 34 SNPs detected for both. 14 SNPs detected by two models on thick flank. Besides 16 SNP were close to LAP3, 6 SNPs nearby LCORL, and 3 SNPs adjacent to BT.94996 in commonly significant SNP. It provides available information for further research into find candidate gene on carcass traits in beef cattle.
