The aim of the study was to predict the correlation of body weights with different body measurements and to derive simple regression equations for estimation of live weight in Sahiwal cattle. Total 194 purebred growing Sahiwal cattle of both the sexes was taken for study and was divided into six age groups (0-6, 6-12, 12-18, 18-24 and 24-36 months). Animals were weighed on a mechanical scale and their heart girth (HG), body length (BL), height at wither (HAW), chest depth (CD) and head to shoulder length (SH) were measured. All the phenotypic correlations among body weight and different body measurements were positive and heart girth (HG) shown highest correlation with live body weight than other body measurements. Study revealed that when HG can be used as a single variable to evaluate body weights more accurately up to age of 36 months in Sahiwal calves.
