local.description.resumoWe developed a study to determine the ideal level of inclusion of soybean oil (SBOil) in the diet without afecting the quantitative and qualitative parameters of the carcass and meat of lambs in a feedlot system; therefore, determining the ideal level of inclusion. Forty male lambs (Santa Inês breed) were used. The initial body weight and age averaged 34.88±3.19 kg and 5 months, respectively. Experimental units (lambs) were randomly distributed in 5 diferent diets: inclusion levels of SBOil: 0, 30, 60, 90, and 120 g/kg of dry matter (DM). The SOil inclusion reduced the DM intake (P<0.001), Total digestible nutrients (P=0.004), and crude protein (P<0.001). Total weight gain (P<0.001) decreased with the SBOil inclusion and subcutaneous fat thickness (P=0.017) showed the same behaviour. The fnal body weight decreased by 42.9 g/kgDM until the inclusion level of 30 g/kgDM; from this level it was reduced by 145 g/kgDM. The hot and cold carcass weights (P=0.013) decreased by 36.6 g/kgDM after including 30 g/kgDM of SBOil. Meat physicochemical composition was not altered (P>0.05). Lower meat tenderness values were obtained at the levels of 60 and 90 g/kgDM. The inclusion above 30 g/kgDM decreased meat tenderness. It is concluded that soybean oil should be included up to 30 g/kgDM in diets. It is important to note that with diets with 60% concentrate, SBOil levels greater than 30 g/kgDM promote yield losses.
