This study investigated the relationship of carcass characteristics such as hot carcass weight and back fat thickness (BFT) and the pH of semispinalis capitis (SC) with the cooking loss (CL) of pork shoulder butt and the CL and Warner–Bratzler shear force (WBSF) of belly. BFT was correlated with the CLs of the butt slices (rs = −0.30) and the belly slices (rs = −0.27 to −0.32). The pH of the SC muscle showed a correlation with the CLs of the butt slices (rs = −0.45) and the belly slices of the 6th and 11th thoracic vertebrae (rs = −0.28 to −0.33). Additionally, the correlations (rs = 0.62 to 0.77) were observed in the CLs among the belly slices. However, the WBSF of the belly slices did not show correlations with others. Therefore, the pH of the SC muscle as well as BFT can be used to obtain information on the CL of shoulder butts and bellies in carcasses.
