The evaluated genotypes were purebred Angus (ANAN), Hereford (HHHH) and Nellore (NENE) and crossbred Angus × Caracu (ANCR), Angus × Hereford (ANHH) and Angus × Nellore (ANNE), finished in two different feeding systems, feedlot or pasture. The ANCR and ANHH genotypes had longer carcasses than NENE (137.0 and 136.9 vs. 125.4 cm, respectively). The NENE and ANNE genotypes showed the longest HL both at 85.6 cm, while the ANCR was superior to ANAN for the HL (80.6 vs. 77.8 cm, respectively). The ANCR showed larger REA when compared with ANAN (78.4 vs. 65.7 cm²) and the NENE showed lower REA than ANCR, ANNE and HHHH genotypes (60.6 vs. 78.4, 77.8 and 74.2 cm², respectively). The FT for which we required a minimum of 3 mm for slaughtering was not influenced by genotype, but grazing animals showed higher FT that those finished in feedlot (6.4 vs. 4.6 mm). Crossbreeding can be used as a tool to improve carcass measurements and achieve suitable finishing regardless the feeding system.
