Sažetak
The distribution of carcass classes in different genotypes of pigs was analyzed on the basis of "The Regulation on the determination of trade categories and classes swine carcasses (NN 79/95) in S-EUROP System. Investigation was carried out on the hogs of Swedish Landrace breed (n=64), ABCD hypor hibrid (n=65) and crossbreed ABSL (n=63) the offspring of the Swedish Landrace sows and AB boars Hypor parent line. On the slaughter line the right half carcasses were dissected after Weniger at al (1963). The proportions of muscle tissue and leg in the carcass were determined by weighing. The areas of the musculus longissimus dorsi (MLD) and the beloning were measured in cm², on the loin cut between the 13th and 14th rib. The obtained results the investigation on muscle tissues and leg in the carcass, area of MLD and belonging fat were; SL 49.23%, 28.87% ,36.26 cm² and 26.87 cm², and ABCD Hypor 55.27%, 30.41%, 43.46 cm² and 20.40 cm². Between groups the significant differencies were at level 1%. The results at crossbreed ABSL 53.14%, 29.78%, 39.89 cm²and 24.36 cm² were significantly different from Swedish Landrace and ABCD Hypor. The Distribution of carcass classes in the investigated genotypes of pigs showed that in the classes S, E, U, R, O, P, there were Swedish Landrace 0%,6.25%, 37.5%, 50.0%, 6.25% and 0%. ABCD: 12.31%, 43.08%, 38.46%, 6.15%, and ABSL: 9.53%, 28.57%, 39.68%, 17.46%, 4.76% and 0%. The established distribution of carcass classes showed that utilized terminal boars for producing F₁, generations gives the possibility to improve the carcass quality on the slaughter line and the value of pig production.
