The paper contains results of morphometric analyses of 229 dressed carcasses of bulls fattened to 500 (498-501) days of age. Data on 11 carcass measures were evaluated in the progeny of sires of Czech Pied cattle and specialized beef breeds of seven commercial meat types - crossbreds of domestic population of dual-purpose cattle and specialized beef breeds (Aa, He, Li, Bm, Pi, Ch, Ba). Slaughter weight of bulls included in groups ranged from 513 to 599 kg, weight gain was in the range of 1058-1211 g in the fattening period. Differences in carcass length between the groups of bulls were at the level of significance (from 126.2 cm in the progeny after sires of He breed to 134.5 cm in bulls of C breed). Production of carcass weight per 1 cm of its length was worst in crossbreds with H sires while the best results (P 0.05) were determined in bulls after sires of beef breeds with large body frame - Ch and Ba. Assessment of bull meatiness in agreement with EUROP did not correspond with these results.
