The effects of supplemental dietary of dried orange peel (DOP) powder on reproductive performance and egg quality traits of crossbred Noi pullets were evaluated, the trial was conducted on a total of 84 crossbred Noi pullets to randomly allocate to 4 dietary treatments in 7 replicates of 3 pulllets each. The formulated basal diet was supplemented with four levels of DOP (0, 0.5, 1.0 and 1.5 g/kg) namedly DC, C0.5, C1.0 and C1.5, respectively. Results showed that the age at point egg production of DC, C0.5, C1.0 and C1.5 was 144, 149, 150 and 154 days, respectively. The age of 50% egg production was earlier in C0.5 (157 days) than in C1.5 and DC (167 days) or C1.0 (181 days). Besides, hen-day egg production and egg yield in C0.5 (46.94% and 41.29 eggs/hen) had a higher tendency (P>0.05) than in DC (42.86% and 40.43 eggs/hen), C1.5 (38.44% and 37.86 eggs/hen) and C1.0 (34.69% and 23.14 eggs/hen). No significant differences were detected among treatments on egg quality parameters except for yolk color a* (P
