Five live body measurements were taken on 142 Friesian crossbred and 49 buffalo male calves belonging to the
rations and fattening unit, Faculty of Agriculture, Alexandria University to study the relationships between body weight
and live body measurements and predict body weight. All simple correlation coefficients between body weight and live
body measurements of Friesian crossbred and buffalo male calves were positive. The highest estimates were between the
heart girth (HG) and body weights in Friesian crossbred and buffalo male calves. HG was the best predictor of body
weight of Friesian crossbred and buffalo male calves throughout the months of fattening period.
