The objective of this study was to determine the accuracy of prediction of body weight
from body measurements in beef cattle. Wither height, chest girth, body length, chest
depth, hip width and hip height measurements were obtained from Holstein, Brown
Swiss and crossbred (n=140). Determination coefficients (R2) of regression equation that
included all body measurements were higher in Brown Swiss and crossbred than Holstein
(92.2, 95.0 and 68.2 %, respectively). However, it was found that chest girth was the best
parameter of all for prediction of body weight in Brown Swiss (R2=91.1 %) and crossbred
cattle (R2=88.8 %) in comparison to Holstein (R2=60.7 %). According to these results, the
body weight estimation of Brown Swiss and crossbred cattle using the body measurements
produced higher prediction accuracies than Holstein but chest girth was the best
parameter to prediction of body weight among all body measurements. However, the
prediction accuracy of prediction of body weight from body measurements and also
chest girth was decreased when the animals frame size was increased.
