Sažetak
Investigation was carried out on hogs of ABCD (n=23) Hypor hybrid produced by mating AB boar with five CD sows of Hypor parent line. Groups of offspring were marked as: A, B, C, D and E. The analyzed characteristics were production traits and on slaughtering line measured meatness by method "two points" (Regulations NN 79/95). Results of hogs within the boar for the analyzed characteristics were as follows: slaughtering weight 100,6 kg, age at slaughtering 195,6 days, weight of warm carcass 79,6 kg. The life daily gains were: of slaughtering weight 513,3 g, of carcass 407,0 g, and muscular tissue in carcass 224,9 g. On the slaughtering line following values were measured; backfat thickness 15,9 mm, muscle thickness of m.l.d. 69,1 mm, muscular tissue in carcass 56,4 %. Statistically significant difference on 1 % level was found for the percentage of muscular tissue in carcass and classes of the hogs between sows D 65,4 % (S) and E 60,7 % (S) in relation to A 53,8 % (U) and B 50,8 % (U), while difference between sow C 56,7 % (E) and B 50,8 % (U) and D 65,4 % (S) and E 60,7 % (S) were at 5 % level. Estimation of the variability of hog classes on the slaughtering line implies that of carcass classes can also be influenced by the technological procedures through elimination of sows on the basis of their performance test.
