This study aimed to evaluate the quantitative and qualitative characteristics of carcass and meat of lambs fed sunflower cake. Were used 28 Suffolk crossbred lambs, with 4 months of age and average weight of 21.00 ± 0.74 kg, divided into four treatments 0% (control), 10%, 20% and 30% of sunflower cake inclusion (% DM). The criteria adopted for the slaughter was body condition score (3, on scale of 1 to 5). The inclusion of sunflower cake did not influence the measurement of length and carcass depth (P > 0.05), pH 24 hours (P > 0.05), yields of commercial cuts (P > 0.05), as well as fat distribution, fat thickness and marbling (P > 0.05). There was a linear effect (P 0.035) and quadratic (P 0.020) on the shear force of the Longissimus dorsi muscle, indicating increase in SF as increase the level of inclusion, was not the case for color parameters L *, a * and b * (P > 0.05). In relation to the control treatment, the inclusion of 20% and 30% of sunflower cake influenced negatively the ribeye area (12.00 and 11.43 cm2, respectively) (P 0.05), cold carcass weight (13.19 and 12.58 kg, respectively) (P 0.05), and confinement time (136.85 and 138.39 days, respectively) (P 0.05). The inclusion of 10% of sunflower cake can be recommended for use in diets of feedlot lambs, since it allows the production of meat and carcasses with quantitative and(AU)
