The effect of breed type (combined and dairy breed), age, carcass weight, weight gains and feeding/rearing conditions (different farms) on the final carcass classification in the SEUROP system was evaluated in 703 Czech Fleckvieh and 642 Holstein bulls. Breed and rearing conditions (feeding) had the highest influence on bulls' classification. There were significant differences between the farms as well as between the two breeds concerning netto weight gain. Significant differences in netto weight gains between the different groups of Holstein bulls (less than 500 g/day, 551-600 g/day, 601-650 g/day and more than 651 g/day) were also observed.
