The objective of the present paper was to assess the quality of dressed carcasses of pig hybrids with different level of meat performance. The first group of hybrids was selected consistently for the expressly meat type, the other was a commonly produced hybrid SLOVHYB-1. Dissection of carcasses was done on the second day after slaughter in both groups to determine the portions of valuable lean cuts (percentages of neck, shoulder, loin and ham with bones weight out of the weight of the side of pork after cooling), followed by detailed dissection into basic tissues (meat, fat, bones, skin). Detailed dissection was done in all body parts, except the head with jowl and trotters. The first group of hybrids, bred for the expressly meat type, had these values of the percentage of valuable lean cuts and lean meat content in vivo and/or post mortem: 51.25 %, 54.10 % and/or 56.85 %. The indicators of carcass value in the control group of slaughter hybrids were as follows: 45.58 %, 50.43 % and 51.27 %.
