Abstract

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<0.05). Variables of hip height and chest, chest width and pin bones, and heart girth showed positive correlations with two or more productive traits of economic interest, such as slaughter weight, hot carcass weight and dressing percentage (P<0.05). Significant correlations were found for most of the variables studied. Linear body measurements such as length and height emerge as a tool that can be useful in the formation of more homogenous lots and to predict the point of slaughter, along with the weight of the animals.
