The trial was conducted to evaluate the effect of different levels of dried sweet orange ( Citrus sinensis) peel on growth performance in broilers. A total of 400 male broiler chicks (Ross-308) were randomly allocated to treatments varying in supplemental DSOP. The dietary groups consisted of five diets fed for 42 days: control diet without feed additive, diet containing 1.5 % feed additive only in starter phase, diet containing 1.5 % feed additive during whole period (starter + grower), diet containing 3 % feed additive only in starter phase, diet containing 3 % feed additive during whole period. The growth responses achieved by broilers from all groups complied with the standards. However, adding up to 3 % DSOP in diet seems to depress feed intake, body weight gain increasing feed conversion ratio of both starter and growing broilers. Conversely, DSOP in the proportion of 1.5 % of feed seems to promote feed intake and weight gain in the period between the 1–21 days of age, indicating that DSOP can constitute a useful additive in the feeding of broilers. Further research is needed to assess the effects of DSOP to improve its suitability as a feed resource for poultry production.
