The objective of this study was to estimate the heritabilities and genetic correlations of meat quality and carcass composition traits in 2 commercial crossbred swine populations: The Maschhoffs (TML) and Smithfield Premium Genetics (SPG). The TML dataset consisted of 1,255 crossbred individuals genotyped and phenotyped for meat quality (MQ), carcass yield (CY) and carcass weight (CW) traits. The SPG population included over 30,000 crossbred individuals phenotyped for a subset of MQ, CY and CW traits, and 1,156 sires genotyped. The two populations were analyzed separately with the use of multiple-trait genomic models. For the TML dataset, models included fixed effects of dam line, contemporary group (CG), gender, as well as a random additive genetic effect and pen nested within CG. For the SPG dataset, fixed effects included parity, gender and CG, as well as a random additive genetic effect and …
