Two experiments were carried out to determine the metabolizable energy of crude glycerin (CG) and to evaluate the effect of adding different levels of CG on broiler performance and yield of carcass and cuts. The first consisted of a metabolism assay using total excreta sampling method aiming to determine the apparent metabolizable energy corrected for nitrogen balance (AMEN). This assay was performed in two phases: 10-18 days (initial phase) and 25-33 days of age (growth phase). The broilers were alloted in a randomized design with two treatments (reference diet and reference diet + 80g/kg of CG inclusion) and nine replications, with ten birds per cage. The AMEN was 2651 kcal/kg and 3013 kcal/kg, for the initial and growth phases, respectively. In the second experiment, 1600 Cobb 500male broilers from 1 to 42 days were alloted in a randomized block experimental design, with 8 treatments and 8 replications of 25 birds...
