Phenotypic characteristics of carcass quality traits of indigenous pig breeds and their hybrids

The research in this work is related to the traits carcass and meat quality of the pure breeds of Mangalitsa (G1; Swallow belly strain) and Moravka (G2) as well as their hybrids of the F1 generation (G3). Ten (10) animals were examined per genotype and both sexes were included for each genotype. For the tested genotypes, the average weight of the warm carcass side for G1 was 98.6 kg, G2 97.4, and G3 98.83 kg. The average weight of the four major carcass side parts - the leg (MH), shoulder (MS), loin rump part (MLB) and abdominal rib part (AR) for the tested genotypes (G1, G2 and G3) was 9.68 kg, 9.46 kg and 9.39 kg; MS 5.51 kg, 5.69 kg and 5.63 kg; for MLB 7.69 kg, 7.76 kg and 8.00 kg, while for AR the average weight of the part was determined to be 5.53 kg, 5.77 kg and 6.23 kg, respectively. The estimated total yield (JUS kg) and the share of meat (JUS %) in carcass sides (OG SFRY, 1985) was for G1 27.84 kg, for G2 28.91 kg and for G3 28.64 kg of meat, while the estimated meatiness was 28.60%, 29.96% and 29.42%. Genotype as a source of variation in carcass quality traits did not influence (p>0.05) the variation of examined carcass quality traits except for the surface, depth, and pH45 of M. longissimus dorsi (MLD; p<0.05). Genotype also had an influence on the colour of MLD (L* and b*; p<0.001). The pH45 and pH24 values of M. semimembranosus and pH24 of MLD indicated normal meat and were not influenced by genotype or gender (p>0.05). Gender had an influence on the surface of the back fat (p<0.05), whereas for other sources of variation in carcass quality traits gender did not influence.
