The estimates of heritability ranged from 0.163±0.011 for WG_210_365 to 0.309±0.028 for RF using the single-trait model and from 0.163±0.010 for WG_210_365 to 0.382±0.025 for BWS using the multiple-trait model. The estimates of genetic correlations ranged from -0.35±0.08 between AFC with BF to 0.69±0.04 between WG_B_120 with BWS. Selection for weights gains, REA, and BWS can improve FMW. © 2013 Elsevier B.V.1-7engBack fat thicknessBeef cattleFemale mature weightRib eye areaRump fatAnimaliaBosArtigo10.1016/j.livsci.2013.04.004WOS:000320836400001Acesso aberto2-s2.0-848798424762-s2.0-84879842476.pdf6064277731903249
