| O objetivo do estudo foi avaliar o ganho de peso (GMD), conversão alimentar (CA), eficiência alimentar (EA), características de carcaça e dos cortes comerciais de ovinos Santa Inês, alimentados com diferentes concentrações de energia metabolizável (2,08; 2,28; 2,47 e 2,69 Mcal de EM kg-1 de MS). Vinte cordeiros, com idade e peso corporal médio de 50 dias e 13,00 ± 0,56 kg, respectivamente, foram distribuídos em blocos casualizados, com cinco repetições. Verificou-se efeito linear crescente (p < 0,05) sobre o GMD. A perda ao jejum, CA, EA, rendimentos de carcaça quente e fria, bem como a perda por resfriamento não foram influenciados (p > 0,05) pelos níveis energéticos das rações. No entanto, os pesos de carcaça quente e fria, e o peso do... |

| The experiment evaluated the meat yield of prepared beef cuts, bone and trimmings of steer and culled cow carcasses. Culled 72-month-old Braford cows, 496 kg live weight and 36-month-old steers, 494 kg live weight were used, all from the same herd and finished on ryegrass pasture. A randomized complete design, with two treatments and 15 replications, was used. Hot carcass weight was lower for cows (248 kg) than for steers (263 kg). Steer carcasses presented better conformation, lower chilling loss, shorter (128.6 vs. 137.7 cm), with longer and thicker limbs compared to cows and similar fat finishing. Steer carcasses showed, compared to cow carcasses, always in the same order, similar side cut yield (13.5 vs. 13.4%), higher forequarter yield (38.4 vs.... |

| The objective of this study was to evaluate total and individual meat yield of boneless cuts, retail cuts, descarded trimmings and carcass bones of 38 Braford castrated steers, slaughtered at 22 months of age after feedlot finishing. Carcasses were classified in three ranks according to fat coverage: even fat coverage over the carcass, with fat thickness of approximately 6-8 mm on the 12th rib; animals with uneven fat cover, with fat thickness of 3-5 mm and steers with insufficient fat coverage over the carcass, with fat thickness of 1-2 mm. Shrinkage losses decreased as fat coverage increased, and it was 2.57, 2.22, and 1.96%, respectively, for insufficient, uneven, and even fat coverage whereas flank yield increased, reaching values of 13.04, 13.47 and... |

| Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at an average weight of 26.24 kg. No significant differences were observed on morphometric measurements, hot (11.67 kg) and cold (11.39 kg) carcass weight, hot (44.46%) and cold (43.37%) carcass yields, biological yield and on cooling losses. There was also no significant effect of silages of different genotypes of sorghum on the weights and yields of... |

| The experiment evaluated total and individual yield of commercial cuts, bones, and trimmings of carcasses from 38 Braford steers at 22 months of age finished in a feedlot. Carcasses were ranked according to three conformation classes (good minus = score 10; good = score 11; good plus = score 12), and three weight classes (heavy = 229.4 kg, intermediate = 205.0 kg, and light = 184.0 kg, ranging from 222.9 to 250.4, 201.5 to 209.0, and 170.0 to 190.3 kg, respectively). Carcass cold shrinkage was not affected by conformation, but it was significantly lower in heavy (1.83%) than in intermediate (2.53%) and in light carcasses (2.30%), which were not different among each other. Carcass flank percentage was not affected by conformation, but it was significantly... |
