A study was undertaken to derive a simple formula for calculating the body weight of pigs using body measurements following multiple linear regression method. Front girth (G1) -just behind the forelegs, hind girth (G2) -just in front of hind legs, average of G1 and G2 (avG), body length (L), height up to withers (H) and neck circumference (NC} were the body measurements used for derivation of formulae. Considering the values for adjusted R', SE of estimate, coefficient of correlation between recorded and predicted weight and residual, the formula involving NC and avG [(W (kg} _ (0.645 NC + 0.475 avG) - 36.2)] was found to be the suitable one.
