ABSTRACT.
Improving meat production traits has increased its importance in sheep breeding. We report novel associations of SNP present in genes related to lipid metabolism and growth with several carcass traits in purebred Texel lambs. Expected progeny differences (EPD) predictions from 461 animals from the Central Progeny Testing of Texel breed in Uruguay were used for the association analysis. Live weights at different stages, ultrasound and post-mortem traits were analyzed. Markers in several genes were associated with growth, carcass and meat quality traits. Among others: PPARGC1A with valuable cuts weight, hot carcass weight and carcass fatness; DGAT1 with live weights, fat thickness, rib-eye area and shoulder weight; CAST with birth weight and fat thickness; GHR with birth weight and carcass fatness, and GHRHR with live weights and fat thickness. Genotypic effects ranged from 0.035 to 0.923 (DGAT1 vs. weaning weight) units of phenotypic SD. Most of the associations described are novel in sheep breeding, deserving further analyses.
