Growth performance, body composition, body conformation and meat quality were evaluated in crossbred pigs
originating from three sire lines selected for leanness and conformation. The crossbred P, which was based on Belgian
Piétrain had a leaner carcass and a better ham conformation compared to the other crossbreds. The presence of the halothane
gene resulted in poorer meat quality in comparison to the homozygous halothane negative crossbred. Body composition
and body conformation were not correlated. Hence, information on both body composition and body conformation
is needed to characterize genetic lines in order to determine the true commercial value of pig carcasses, especially when
meat quality has to be taken into account.
