The production characteristics of fatteners in this paper were examined in two farms of pigs in the Republic of Serbia. The research included 1166 pigs of both genders (female animals and male castrated heads) with various genotypes. Research examined influence of sire breed, sire within sire breed, gender of the pigs and the mass at the end of the fattening on the following characteristics of the fatteners: daily gain of the warm carcass side mass (PTP), rump fat thickness (DSK), backfat thickness (DSL) and sum of the fat thickness rump+back (DSKL). The pigs in this research come from the following sires: Large White (LW), Swedish Landrace (SL), Duroc and Crossbreed H × D. Data processing was done using the Harvey computer program. It was determined that all the involved effects in the model show a different level of influence on the researched traits (P < 0.05; P < 0.01; P < 0.001), whereas only one factor, sire within sire breed H × D does not influence the expression of the charac...teristic gain of the warm carcass side mass (P > 0.05).
