The objective of this study was to evaluate carcass characteristics of steers and cull cows from two genetic groups, under different feeding frequencies. Twelve steers and twelve cull cows were used and each category consisted of six animals 5/8 Charolais (C) - Nellore (N) and six animals 5/8NC, under three feeding frequencies: twice a day (7 a.m. and 7 p.m.); three times a day (7 a.m., 1 p.m. and 7 p.m.) and four times a day (7 a.m., 11 a.m., 3 p.m. and 7 p.m.). The animals were feedlot finished receiving corn silage as forage and concentrate based on wheat bran, corn ground, soybean meal, limestone and salt, with a forage:concentrate ratio of 40:60. The increase in feeding frequency did not influence the animal carcass quality. The cows showed higher slaughter, hot and cold carcass weights (509.7; 280.0; and 277.1 kg) compared to the steers (414.5; 230.5 and 228.1 kg), but the hot and cold carcass dressing percentages and carcass chilling loss were similar in the steers and cull cows. The characteristics that express carcass muscularity were better in the cows that had greater thigh thickness (25.88 vs 23.33 cm). The metrical characteristics were more expressive in the cows which had longer carcasses (132.8 vc 122.3 cm) and greater fat thickness (6.21 vs 3.83 mm). The cows also were superior for forequarter and sawcut weights (103.5 and 133 kg) compared to the steers (84.7 and 111.8 kg), which presented higher sawcut percentage in the carcass (49.06 vs 4
8.04%). Between the genetic groups, 5/8C3/8N animals presented higher thigh thickness, Longissimus dorsi area and carcass length (25.7 cm; 64 cm² and 137 cm) compared to 5/8N3/8C (23.5 cm; 57 cm² and 124.8 cm).
