Prediction of body weight on the basis of body measurements in karan fries cows and murrah buffaloes*

The relationships between body weight (BW) and body measurements such as heart girth, body length, abdominal girth, height at hook and height at withers of 199 Karan Fries (KF) cows and 268 Murrah buffaloes of NDRI herd, were investigated. The principal objective was to develop a regression equation that could be used to estimate BW. The prediction equations developed to predict the body weight from the body measurements gave an accuracy of 72.24 percent (R²) in KF cows and 66.90 per cent (R²) in Murrah buffaloes. Body measurements, mainly HG and AG were better related with BW 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.
