Objective: A study was conducted to determine the effect of diet supplemented with selenium (Se) from different sources on feed digestibility, growth performance, carcass percentage and meat selenium of broilers. Materials and Methods: A total of 200 day-old broiler chicks were used in this study. The broiler chicks were placed into five brooder cages for 7 days prior to allocate them into 20 pens. Each pen was equipped with a drinker and feeder. The basal diets (T-1) were supplemented with high Se feedstuffs: Se commercial feed additive (Sel-plex; T-2), tuna fish meal (T-3), Moringa oleifera seeds meal (T-4) and snail meal (Melania testudinaria, T-5), Diets and water were provided ad libitum. A completely randomized design with five treatments and four replications was used. Data were with analysis of variance. Differences among treatments were tested for significance by Tukey Test. Results: The study indicated that treatments produced significant effects on body weight gain and feed intake, Se intake, dry matter digestible intake, Se digestibility, carcass percentage and breast meat Se. Selenium intake, digestible Se intake and carcass percentage were higher in T1, T3, T4 and T5. Addition of Se in the diets in the forms of Sel-plex and snail meal significantly increased body weight gain, Se digestibility and breast meat Se. Feed intake and dry matter digestible intake were only affected by Sel-plex supplementation. Conclusion: Diets containing Se from either Sel-plex or snail meal produced heavier birds, higher in Se digestibility and Se meat than those of birds fed the control diet.
