Abstract

The present study was carried out to find the correlation between different live animal physical measurements and some economically important carcass parameters and to predict these carcass parameters using multiple linear regression models. Heart girth and flank girth showed a highly significant (p<0.01) correlation with carcass weight in all three weight groups. Angle showed significant correlation with carcass weight in group I and highly significant correlation in group II. Heart girth also showed a highly significant (p<0.01) correlation with the total meat yield of pig in groups I and II. Dressing per cent was not significantly correlated with any of the live animal physical measurements in groups I and III. But the correlation was highly significant with heart girth in group II. Multiple linear regression analysis revealed that live animal physical measurements played a minor role on the majority of carcass characteristics, while the heart girth was critical in several instances. Physical measures of the live animals predicted carcass weight better than other carcass parameters. (R2=0.623 – 0.924)
