SUMMARY The objective was to assess the effect of inclusion of crude glycerin (CG) replacing corn in the diet of feedlot Pantaneiro lambs on the non-carcass components, regional and tissue composition, and carcass traits. Were used 24 not castrated males, in a completely randomized design with four treatments (0, 2.5, 5.0 and 7.5% of CG on DM basis). There was no effect of GB inclusion on non-carcass components. There was a quadratic effect for hot carcass weight, with lower value to 2.5% of CG. Regional and tissue composition of the carcass was not affected by the substitution of corn by CG. The tissue composition of shoulder and leg and instrumental traits of the shoulder were not affected by CG. There was a quadratic effect for the yellowness of the leg, with high value for 5.0% of GB. The ether extract content of shoulder showed decreased linear effect. The use of 7.5% of CG, in dry matter, can be recommend to replace corn of feedlot diets, without changing carcass traits and meat quality.
