Abstract
The relationships between body weight (BW) and body measurements such as heart girth, bodylength, abdominal girth, height at hook and height at withers of 199 Karan Fries (KF) cows and 268Murrah buffaloes of NDRI herd, were investigated. The principal objective was to develop a regressionequation that could be used to estimate BW. The prediction equations developed to predict the bodyweight from the body measurements gave an accuracy of 72.24 percent (R2) in KF cows and 66.90per cent (R2) in Murrah buffaloes. Body measurements, mainly HG and AG were better related withBW in both the breeds, KF cows (r = 0.78 and 0.74) and Murrah buffaloes(r = 0.72 and 0.75). So,HG or AG can alone be used for prediction of body weight.
