| The experiment was carried out at the Comigo Technology Center, in Rio Verde, State of Goiás, Brazil, with the objective of evaluating the effects of supplementation with calcium butyrate, as a growth promoting agent for the duodenal mucosa and Bacillus subtilis as a probiotic performance enhancer in feedlot cattle. Calcium butyrate (5 and 10 g per animal per day) and Bacillus (10 g per animal per day) were added to a basal diet. There were used 85 Nelore bulls, with average weight of 315 ± 7 kg. The experiment lasted 118 days, including the adaptation period, until slaughter at 30 months of age. Diets were distributed in a completely randomized design with four treatments, where: T1 = control (basal diet); T2 = basal diet + 5 g calcium butyrate; T3 =... |

| Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four slaughter-weight classes, namely <340, 340-370, 370-400, or >400 kg. Back fat thickness was not influenced (p > 0.05) by slaughter weight in any of the forms it was expressed (mm or %), averaging 5.3 mm. Loin eye area in cm2 increased (p < 0.05) with the increase in slaughter weight. Animals slaughtered at a live weight (LW) of more than 400 kg showed better (p < 0.05) carcass conformation than the other experimental groups (9.8 points). Heifers slaughtered at over 400 kg LW had a more compact (p... |
