Corn grains and soyabean meals were replaced by tomato seed at levels of 6, 12 and 18 % and tomato pomace at levels of 3, 9 and 12 %. At first, the metabolizable energy of tomato seed and pomace was determined by the Sibbald method. In this experiment, 504 commercial broiler chicks (Ross 308) were used for 8 weeks (from 7 to 56 days old ) in a completely randomized design in 7 treatments with 4 replications per treatment. After 21 days, protein digestibility of the ration in illeum was determined. Apparent metabolizable energy was 3394 kcal/kg for seed and 2329 kcal/kg for pomace and crude protein was 31, 22.7, respectively . The result showed that body weight, protein digestibility of rations in illeum and carcass characteristics were not significantly different . Best energy and protein conversion efficiencies were obtained at the level of 6 % seed and 9 % pomace, that were not significantly different from control treatment. Cheeks fed with seed and 12% tomato pomace had significantly (p SP - 393 EP - 401 AU - Chakraei, A. AU - Pourreza, J. AU - Tabeidian, A.
