54 hybrid pigs (Czech Large White (CzLW) x Czech Landrace (CzL)) x CzLW boars - A combination and 52 hybrid pigs (CzLW x CzL) x (Pietrain x Hampshire) - B combination were determined to their slaughter weight, percentage of lean meat and percentage of intramuscular fat (IMF) in MLLT muscle. The A combination of crossbreds had an average slaughter weight 104.99 kg, 53.08 of lean meat and 0.98 percent of IMF. The B combination the crossbreds had an average slaughter weight 109.48 kg, 54.40 percent of lean meat and 1.24 percent of IMF. In both combinations there were found negative correlations between percentage of lean meat and slaughter weight. Between content of IMF and lean meat percentage a small but negative correlations were counted too. The hybrids with 25 percent share of Pietrain had for about 1.32 percent more meat content than hybrids which were created from the native breeds (combination A). However the meat of hybrid A combination had a lower IMF content in the almost each subclass according to SEUROP classification than B combination hybrids
