In this work it was aimed to evaluate Pearson correlations between body measurements, carcass characteristics and production of 35 Nellore bulls, confined for 96 days, with 402±14.90 kg and 18 months old. Weightings, ultrasound images and 14 measurements were obtained at the beginning of each experimental period and before slaughter, totaling four weight ratings of ultrasound images and measurements per animal. For the evaluation of body measurements and ultrasound images with carcass traits the values from the last measurement were considered. The images were made along with weighing animals through a Scanner, and measurements with a tape measure and a zoométrica cane, and these were correlated with each other and with productive and carcass characteristics. For measures of loin eye area evaluated by ultrasonography, it were found positive correlations with body length (0.32), rump (0.36) and thigh (0.20); withers height (0.20) and pelviano contour (0.38) (P |
