The studies included carcasses of porkers purchased in the Lubelszczyzna region; the data covered the years 2005-2006. Estimation of carcass quality was based on the muscling and adiposity measurements carried out by an ultrasound unit Ultra-Fom 300. The gathered material was sorted out according to a quarter of purchase and carcass mass. In the estimated years, the mean carcass meatiness averaged 51.15%. Carcass quality expressed as thickness of backfat and loin eye height in carcasses obtained in the successive years showed some changes subject to a quarter of the year studied. The majority of the evaluated carcasses ranged between 80-90 kg BW interval.
