Abstract
This paper analyses the quality of carcasses and meat from Swedish Landrace (meat production type) and Black Slavonian (meat and lard production type) pig breed. 20 pigs of each type were fed ad libitum until they were fattened up to reach 105 kg of body weight. Carcasses were dissected according to the modified method introduced by Weniger et al. (1963). Swedish Landrace carcasses had a significantly greater (p<0.05) proportion of shoulders, while Black Slavonian pig carcasses had a greater proportion of lard. The ham, shoulder, loin and belly-rib of Swedish Landrace had a significantly (p<0.01) higher proportion of meat than corresponding parts of Black Slavonian pig carcasses. The meat yield of Swedish Landrace carcasses (56.49 %) was significantly (p<0.01) higher than the meat yield of Black Slavonian pigs (45.05 %). The meat of Black Slavonian pigs demonstrated superior physicochemical and sensory properties than examined meat of Swedish Landrace, manifested as a result of higher pH1 value (6.72 : 6.10), greater water holding capacity (4.34 cm2 : 6.99 cm2, greater consistency (2.47 cm2 : 3.88 cm2), lower degree of lightness L* (51.74 : 61.25), higher degree of redness a* (17.30 : 10.50), lower water content (67.78 % : 73.10 %), higher fat content (6.97 %: 1.71 %), higher degree of marbling (6.00 : 2.00) and juiciness (5.90 : 5.20), as well as preferable aroma (5.40 : 4.50) and flavour (5.70 : 4.80).
