NAKEV, Zh. and A. APOSTOLOV, 2002. Prediction of lean meat percentage of pig carcass by morphological analysis of different parts. Bulg. J. Agric. Sci., 8: 653–656

The objective of the study was to investigate the possibilities of estimation carcass quality according to the requirements of EC using results from complete carcass analysis of separate parts of skinned pigs.
120 pigs (60 pigs from the Large White breed and 60 pigs from Landrace) were objects of the study. The pigs were slaughtered at 94.7 kg live weight and dissected by the standard national method.
The highest values in absolute (kg) and relative (%) units for lean meat trait in the real ham (4.174 kg, 64.618%) were established.
The correlation coefficients between lean meat percentage in the carcass and lean meat percentage in the real ham, the breast part and the waist part rp = 0.889, rp = 0.862, rp = 0.860 (P ≤ 0.001) respectively, gave us a reason for expecting the highest accuracy using them to predict carcass quality.

Key words: carcass quality, correlation, regression
