The objective of this study was to evaluate the influence a finishing diet containing natural additives fed for 94 days on animal performance, carcass, and meat quality characteristics of crossbred bulls (1/2 Angus × 1/2 Nellore). Forty-eight bulls (initial BW 318 ± 4.7 kg and initial age 22 months) were used in a completely randomised design. Bulls were fed one of four diets: (1) CON – Control; (2) CCO – addition of 4 g/animal.day of a mix of essential oils from castor bean and cashew; (3) MIX – addition of 4 g/animal.day of a mix of essential oils (oregano oils, castor bean, cashew); (4) YST – addition of 4 g/animal.day of yeast. Bulls were finished in feedlot (in individual pens) and slaughtered at an average weight of 469 ± 6.7 kg. Final BW, hot carcass weight and average daily gain were greater (P < 0.05) in MIX diet than in the three other diets. However, DM intake, G : F, fat thickness, longissimus muscle area, marbling, and meat colour were similar (P > 0.05) among the four diets. The carcass conformation score was higher (P < 0.05) for bulls that were fed with the YST diet and similar for the three other diets. Meat from CCO had a reduced (P < 0.05) cooking loss when compared with CON diet. Shear force from MIX diet had lesser values (P < 0.05) than meat from YST diet, and it was similar among CON and CCO diets. There was no diet effect (P > 0.05) on lipid oxidation, moisture, ash, and total lipids contents. C14:0, C14:1 n-9, C16:0, C18:1 n-9, C18:1 n-7 and C18:3 n-6 fatty acids in intramuscular fat from the longissimus muscle were affected by the inclusion of additives in the diets. SFA, MUFA, PUFA, n-3 and n-6 fatty acid percentages, and the ratios PUFA : SFA and n-6 : n-3 were similar (P > 0.05) among diets. In conclusion, adding a mix of oregano, castor bean, and cashew oils in the diet improved the performance of the bulls, but meat characteristics did not significantly change.

ABSTRACT. The influence of the replacement of soybean meal by crambe crushed in concentrated supplement at proportions 0, 5, 10, 15%, on the performance and carcass traits of grazing cows is assessed. Within a completely randomized design, twenty Nellore cows, fed on Brachiaria humidicola, were supplemented during the rain-drought transition period and monitored with regard to weight and body conditions every 28 days. Total forage mass and percentages of leaf, stem and senescent material were quantified in loco. The estimation of forage quality consumed by animals was performed by the simulated grazing method. There were no significant differences between the levels of inclusion of crambe crushed on animal performance or carcass characteristics. Replacement did not affect weight, carcass yield, Brazilian commercial cuts, morphometric measures of carcass, characteristics of loins, thickness of carcass fat, perirenalpelvic fat and total meat. Replacement of soybean meal by crambe crushed up to 15% in the concentrated supplement does not affect performance and carcass characteristics of cows finished on pasture.Keywords: by-product, Brachiaria humidicula, Longissimus muscle area, rib cut.Torta de crambe em suplementos para vacas de descarte: desempenho animal e característica de carcaça RESUMO. Avaliou-se a influência da substituição do farelo de soja pela torta de crambe no suplemento concentrado sobre o desempenho e as características de carcaça de vacas em pastejo, nas proporções 0, 5, 10, 15%. O delineamento foi inteiramente casualizado, em que foram utilizadas 20 vacas Nelore, que foram suplementadas durante a época de transição água -seca em pastagem de Brachiaria humidicola, e monitoradas quanto ao peso e condição corporal a cada 28 dias. Na pastagem foram quantificadas a massa de forragem total e as proporções de folha, colmo e material senescente. A estimativa da qualidade da forragem consumida pelos animais foi feita pelo método do pastejo simulado. O desempenho dos animais e as características de carcaça não apresentaram diferenças significativas entre os níveis de inclusão de torta de crambe estudados. Deste modo, não foram influenciados os pesos e os rendimentos de carcaça, os cortes comerciais brasileiros, as medidas morfométricas, as características do lombo, a espessura de gordura da carcaça, a gordura perirenal-pélvica, bem como a quantidade de carne aproveitável total. A substituição do farelo de soja pela torta de crambe até 15% no suplemento concentrado não afeta o desempenho e as características de carcaça de vacas terminadas a pasto.Palavras-chave: sub-produtos, Brachiaria humidicola, área do músculo Longissimus, contra filé.
