Abstract
Objective of this paper was to evaluate phenotypic variability of carcass side traits and quality of meat of fatteners (male castrated heads) of Moravka breed (M) and Mangalitsa (swallow-belly Mangalitsa - LM). The quantity and content of meat were determined based on dissection of left carcass sides (Walstra and Merkus, 1996). Also, nutritive properties of musculus longissimus dorsi (m.l.d.) were established. Obtained data were processed using GLM procedure of the program package SAS 9.1.3 (SAS Inst.Inc., 2002-2003). Results of the study show that Moravka fatteners had longer carcass sides (+6.82 and + 5.00 cm) compared to Mangalitsa breed, corrected to average body weight at slaughtering. Fatteners of M breed had in average higher total mass of back-loin part (+0.685, P<0.05) and average quantity of muscles in the same part of carcass side (+0.631 kg, P<0.01), compared to fatteners of LM breed. Also, they had higher quantity of muscle in belly-rib part (+0.237 kg, P<0.05) compared to LM. Share of muscle tissue in back-loin and belly-rib carcass side parts corrected for WCC, was higher in M carcass sides than in LM (P<0.01). Conversely, muscle tissue content in shoulders of Mangalitsa was higher (+4.8% ; P<0.05) than in Moravka. Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides. In m.l.d. of Moravka water content was higher (+6.1%, P<0.01), content of total lipids (-6.5%, P<0.05) and cholesterol (-19.68 mg/100 g, P<0.001) was lower than in Mangalitsa.
Highlights
In Republic of Serbia three native autochthonous pig breeds are registered: Mangalitsa, Moravka and Resavka
Share of muscle tissue in carcass sides of M pigs was by 4.3% higher compared to LM carcass sides
2003) show that there is less than 40% of lean meat in carcass sides, but this is enough for production of high quality ham
Summary
In Republic of Serbia three native autochthonous pig breeds are registered: Mangalitsa, Moravka and Resavka. The interest for native autochthonous breeds has increased for the purpose of gene preservation and production of meat products manufactured in traditional way. Mangalitsa is typical fat breed, i.e. in carcass sides there is 65-70% of fat and approx. 2003) show that there is less than 40% of lean meat in carcass sides, but this is enough for production of high quality ham. Moravka is breed of combined production abilities and with more meat in carcass sides and significantly less fat (Petrović et al, 2007, 2007a, 2009). Objective of this study was to evaluate phenotypic variability of the quality of pig carcass sides and meat of Moravka and Mangalitsa breed fatteners
