Between the carcasses with S, E and U conformation classes, there were no significant differences in pH of the LL muscle from 35 min to 72 h. We found, however, that the extent of the decrease in pH (from 35 min to 72 h) was significantly higher (p ≤ 0.05) in E carcasses and lower in U carcasses. Based on mean levels, one could see a tendency that the higher the carcass conformation, the higher the electrical conductivity (EC2 and EC24) in the LL muscle. There was no significant relation between conformation class and color characteristics or drip loss in the LL muscle.
