Objective of this paper was to determine the distribution of tissues in four major carcass side parts from fatteners of Swallow-Belly Mangalitsa and Moravka breeds. The study included 42 animals (male castrated and female pigs) of Swallow-Belly Mangalitsa strain (LM, n=19) and Moravka (M, n=23). Animals were kept and reared in the same farm conditions with free ranges. During fattening, animals were fed two complete mixtures containing 15 and 13% crude proteins. Dissection of left carcass sides and calculation of the meat percentage were carried out according to EU reference method (EC, No.3127/94). Obtained data was processed using GLM procedure of the software package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Pre-slaughter body mass influenced variation of the mass of warm and cooled carcass sides (P is less than .0001). Pre-slaughter body mass of SBM and M had impact on variation of the subcutaneous fat tissue and skin in the thigh and shoulder, and on bone tissue in the shoulder. Fatteners of Moravka breed had higher average mass of back-loin part of the carcass sides (P is less than 0.01) and mass of subcutaneous fat tissue including the skin (P is less than 0.05) compared to Swallow-Belly Mangalitsa. Share of muscle tissue of this carcass part in total mass of muscle tissue in all four carcass side parts was higher in Moravka breed pigs (+2.18%, P is less than 0.01). Male castrated pigs had lower values of average mass of the thigh/leg (P is less than 0.05), lower values of muscle tissue mass in the thigh/leg (P is less than 0.01) and higher share of bone tissue (P is less than 0.05) compared to female pigs. In the belly-rib part, castrates had less intermuscular fat tissue (P is less than 0.05) and bone tissue (P is less than 0.05) than female pigs.
