Summary: Abstract: This study was carried out to analyze the association between meat tenderness (WBSF) and growth traits, which were birth weight (BW), weight at 120 (W120), 210 (W210), 365 (W365) and 450 (W450) days of age, and average daily gain (ADG) in 654 Nellore cattle. The data were from Guaporé Agropecuaria?s OB Choice Program. Pearson?s correlations and analysis of variance were used to analyze the phenotypic relationships, using software R. A low and no significant correlation between WBSF and growth traits (-0.15, -0.11, -0.06, 0.04, 0.02 and 0.08 for BW, W120, W210, W365 and W450, respectively) was estimated in this study, inferring that the selection for growth traits did not influences the meat tenderness. Segregating groups that presented higher WBSF also presented higher average daily gains and higher body weight.
