Summary: Abstract: The aim of this study was evaluate the correlation between meat tenderness (WBSF) and carcass traits (rib eye area (REA), backfat thickness (BF), rump fat thickness (RF)) in Nellore cattle and also estimate if there are differences regarding carcass evaluation considering segregation groups for WBSF. The data set is from 654 Nellore animals, born between 2006 and 2015. The correlation analysis among the traits was conducted using R program and the variance analysis was estimated to verify the association between meat tenderness and carcass traits. The genetic correlations between WBSF and REA, BF and RF were of a low magnitudes (-0.13, -0.04 and 0.03, respectively). The significant analysis showed statistical difference only among the AOL and WBSF group. The results support the conclusion that carcass selection will cause little influence in meat tenderness, because WBSF also is affected by ante and post mortem factors.
