This experiment was an obligation of Greece to the EEC to apply objective pig carcass classification, based on the carcass lean meat content. By using 3 electronic devices, we measured on the left half of 130 pig carcasses the backfat thickness in mm including rind at the positions 8 cm LR and 6 cm 3/4 LR, and the thickness in mm of the Longissimus Dorsi muscle at the position 6 cm 3/4 LR. We found the % lean meat content of each carcass by complete cutting with knife to muscle tissue, bones, subcutaneous fat, inter muscular fat and connective tissue (Kulmbach method). We correlated these 4 variables finding thus one regression equation for each electronic device. Fixing the terminal software of each device with the proper equation, we can now estimate on line; by probing twice in the right positions of the carcass its lean meat content.
