Abstract The relationships between the composition and specific gravity of bacon-weight pig carcasses were investigated using carcass data from two fattening trials. In one trial bacon sides from 42 Large White pigs were fully dissected, and in the other bacon sides from 64 mainly crossbred pigs were minced and chemically analysed. The specific gravities of all six carcass joints were individually measured and correlated with their own composition and that of the whole carcass in Trial One, and with the composition of the whole carcass only in Trial Two. Specific gravity was strongly correlated with carcass composition, giving residual standard deviations between 1.47% and 1.75%. These residual standard deviations were further reduced by the inclusion of carcass measurements with specific gravity data in multiple regression equations. In both trials the correlation between whole carcass composition and specific gravity of the rib end was significantly higher than the corresponding shank end correlation. V...
