The test focussed on the evaluation of production traits, i.e. fattening performance and quantitative aspect of the carcass value in 4 genotypes of pigs by means of station tests. The tests included 288 hybrid pigs of the VEPIG and (LWd ×L) genotypes mated by hybrid-boars of (PN×D), (PN×H), (LWs×BL). The outcomes have proved the existence of marked genotype differences in the production traits and, consequently, also in the economics which means for the pig breeders in the current period a significant measure conducing to the improvement of the economics of pig breeding. As the best, there has been proved the VEPIG genotype of pigs, which has shown the best results in all qualities of the fattening performance and carcass value. This genotype has also reflected best its highest growth intensity in the formation of meat which has been manifested positively in the classification of slaughter pigs, i.e. the profit per a slaughter pig in the amount of 625 CZK. In contrast, the other combinations have shown a loss which in the (LWd×L) × (LWs×BL) genotypes amounted to 324.50 CZK, in (LWd×L) × (PN×D) 228 CZK and in (LWd×L) × (PN×H) 279 CZK. Therefore it has to be stated that a deliberate selection of a suitable genotype is of a vital importance in order to be able to face the current considerably unfavourable situation in pig breeding.Keywords:
