The aim of this work was evaluate introduction of byproducts of oleaginous in lambs feeding. Diets were composed for 30% of Tifton hay and 70% of concentrate based on corn grain, soybean meal, soybean cake, sunflower cake and peanut cake, limestone and mineral mixture, as dites: FS – control with soybean meal, TS – soybean cake as part of the concentrate, TG sunflower cake as part of the concentrate and TA – peanut cake as part of the concentrate. For performance evaluating 24 Santa Inês lambs with initial age and weight of 70 days and 19 + 2 kg, according to a completely randomized design. For digestive evaluate, weight Santa Inês sheep with initial age and weight of 70 days and 16 + 1.2 kg, adapted to the use of bag, for collect feces. Animals were distributed in a replicated 4 x 4 Latin Square and means were compared by Tukey’s test with 5% significance level. By the performance trial, duration of confinement, weight gain, fed conversion and the dry matter intake were not affected (P>0,05), with averages of 54.29 days, 259 g/day, 4.29 kg of DM/kg and 1.32 kg/day, respectively. There were no difference P>0,05) for intake DM, OM, CP, CT and CE among diets, digestibility trial with averages of 76.23; 74.47; 76.44; 41.12; 73.00 and 93.00%, respectively. There were no differences for digestibility DM, OM, CP, ADF, CT and NCF. The partial substitution of the soybean meal for byproducts of oleaginous was a good proteic alternative in the feeding of lambs.
