Four groups totaling 36 young bulls were placed in a dry lot and individually fed a ration of 66% TDN. There were two groups of ten Nellore bulis (Nellore I and Nellore 11) and two groups, one of ten one-quarter Marchigiana-Nellore and one of six one-half Marchigiana-Ncilore bulls (crossbred 1 and crossbred II, respectively). Nellore 1 bulis averaged 689 days of age and the other three groups averaged 613 days of age at the start of the trial. All animals were randomly assigned to three slaughter time groups (1, 2 and 3) and were fed for 119, 152 or 175 days. flie crossbred Il bulls had heavier (P < .05) live weights (5 13.5 kg) at slaughter than the Nellore 1, Nellore II and crossbred I groups (476.0, 464.5 and 479.0 kg respectively). Consequently, crossbred I1 bulls showed heavier (P < .05) bot and chilled carcass weights than the other groups. Also the crossbred I1 buils had less (P < .05) 12th rib fat cover (3.5 mm) with Nellore 1[1 bulls having the thicker 12th rib fat cover (6.1 mm) and Nellore 1 and crossbred I groups being intermediate (4.7 and 4.6 mm respectively). Loin eye area was larger (P < .05) for crossbred 11 (79.65 cm 2 ) than for Nellore 1, Nellore I1 and crossbred 1 groups (70.39, 68.57 and 65.93 em2 respectively). A rnarked advantage was shown for the crossbred 11 group from the starídpoint of producing greater quantities of lean meat without excess waste fat. This group had higher (P < .05) proportion of edible portion from the special hindquarter (33.65%), higher (P < .05) proportion of total edible portion (76.30%) and lesser amounts of trimmable fat (6.96%).
