The paper presents the experimental results regarding the influence of the genetic types of boars on the productive qualities and the specific feed consumption of hybrids, as well as its modification in the growth and fattening process with the increase in the age of the pigs. The object of the study was different genetic boar types: purebred Pietrain and Duroc, as well as Duroc x Pietrain hybrids, imported from France and (Great White x Landrace x Pietrain) x Pietrain, imported from Romania, on the basis of which hybridization schemes were developed where the maternal form was Landrace x Great White in all variants. In all age periods, a higher specific feed consumption (3.1 kg feed/kg weight gain) was reported in the young pigs from the lot where the Duroc breed, known for its relatively higher fat accumulation in the adipose layer, was used for hybrid production. In the other hybrid types specific feed consumption ranged between 2.79 and 2.92kg. The genetic type of the boars was found to play a determining role on carcass and meat quality. According to production testing, backfat thickness in hybrids varied between 20.2 and 22.5 mm at a weight of 110-120 kg. The differences between tetraracial and triracial hybrids were 1.3 mm. Experimental data confirm the viability of using hybrid boars according to consumer requirements and the specifications of the final product delivered for processing.
