A genome-wide association scan in pig identifies novel regions associated with feed efficiency trait
Original language description
Feed conversion ratio (FCR) is an economically important trait in pigs, and feed accounts for a signi?cant proportion of the costs involved in pig production. In this study we used a high-density SNP chip panel, Porcine SNP60 BeadChip, to identify the association between FCR and SNP markers and to study the genetic architecture of the trait. After quality control, a total of 30,847 SNP that could be mapped to the 18 porcine autosomes (SSC) using the pig genome assembly 10.2 were used in the analyses. Deregressed estimated breeding value was used as the response variable. A total of 3,071 Duroc pigs had both FCR data and genotype data. The linkage disequilibrium (r2) between adjacent markers was 0.56. Two association mapping approaches were used: a linear mixed model (LMM) based on single-locus regression analysis and a Bayesian variable selection approach (BVS). A total of 79 signi? cant (P < 0.0001) SNP associations on 6 chromosomes were identi? ed by LMM analyses. Out of these, 10 SN
