The aim of the thesis was to characterize the growth, fattening performance and carcass value of pigs and the factors which influence them. The attention was devoted to classification of pig carcasses in SEUROP system. There were observed feeding parameters of 20 batches from January 2014 to April 2015. The average quantity of pigs in one batch was 471.3 heads. The average initial weight was 26.9 kg, the average period of fattening lasted 106.7 days, the average slaughter weight was 112.7 kg, the average daily weight gain was achieved 0.81 kg/head/day, the average consumption of complete feed mixture for 1 fattening day was 2.19 kg, the average consumption of complete feed mixture of 1 kg weight gain was 2.72 kg, the average loss caused by mortality during the fattening course was 2.26%. There were used 2 737 of carcasses in the following experiment. The pigs were slaughtered in slaughterhouse A and in slaughterhouse B. The average carcass weight was 89.2 kg. The average lean meat content was estimated at 57.7%. In the class S there were classified 446 carcasses (16.3%) with an average lean meat content of 61.3%, in the class E there were classified 1 870 carcasses (68.3%) with an average lean meat content of 57.9%, and in the class U there were classified 421 carcasses (15.4%) with an average lean meat content of 53.5%. It was shown that in case of increasing the carcass weight of 1 kg, the lean meat content was reduced by 0,12 %.
