The objective of the research was to compare collagen characteristics, general meat quality parameters and carcass characteristics of three different muscles from freely pasturing Mangalitza Red breed and highly bred domestic/commercial pig breed. Collagen content and collagen solubility was analyzed by hydrolyzing the three different muscle samples. Meat quality parameters were analyzed previously by Natural Resources Center (Luke). The pH of Mangalitza LD muscle varied from 5.41 to 5.64, SM muscle from 5.53 to 5.75 and IS muscle from 5.74 to 5.87, IS having higher pH than the two other muscles (P < 0.05). The pH of commercial pig LD muscle varied from 5.47 to 5.75, SM muscle from 5.52 to 5.77, and IS muscle from pH 5.96 to 6.51, IS having higher pH than the two other muscles (P < 0.05). Breed had effect on pH of muscle IS (P < 0.05), but no effect on muscles LD or SM (P > 0.05). The color of muscles of Mangalitza was darker than commercial pig’s in all the three muscles (P< 0.05). In Mangalitza, LD was lighter than SM and IS, but in commercial pigs, LD and SM were lighter than IS (P < 0.05) Collagen content of all three muscles of Mangalitza differed from each other (P < 0.05) and the collagen content of LD and SM were lower (P < 0.05) than of commercial pig’s collagen content. In commercial pig, collagen content of LD and SM muscles were lower than in IS muscle (P < 0.05). Collagen solubility of all three muscles of Mangalitza differed from each other (P < 0.05) and the collagen solubility of SM and IS were lower (P < 0.05) than of commercial pig’s collagen solubility. In commercial pig, collagen solubility of LD and SM muscles were lower than in IS muscle (P < 0.05). In contrast to collagen content, collagen solubility of LD muscles did not differ between the breeds (P > 0.05). The amount and solubility of collagen did not deviate from normal; it can be concluded that this study did not provide any new information other than the collagen content and solubility of Mangalitza Red breeds muscles of LD and SM.
