The aim of this experiment was to study the effects of dried citrus sinensis on intestinal pathogens of broilers. Studied treatments were included treatment 1: Control treatment included standard diet without additive aterials; treatment 2: standard diet + 1.5% dried citrus sinensis peel during 1-21st days; treatment 3: standard diet + 1.5% dried citrus sinensis peel during 1-42nd days; treatment 4: standard diet + 3.0% dried citrus sinensis peel during 1- 21st days; treatment 5: standard diet + 3.0% dried citrus sinensis peel during 1-42nd days. The results from the mean of Escherichia coli in ileum in the day 42 indicated that the mean of treatment was significantly different (p<0.05). The lowest mean was related to 1.5 % treatment up to end of the rearing period and the highest rate was related to control treatment. The results from the mean of Escherichia coli in cecum in the day 42 indicated that all of treatment was significantly different with control (p<0.05). The lowest mean was related to 1.5 % treatment up to end of the rearing period and the highest rate was related to control treatment. The results from the mean comparison of coliforms in ileum in the day 42 indicated that experimental treatment was significantly different with control (p<0.05). The highest mean was concerned to control treatment and the lowest one was related to treatment which consumed 3% (DCSP) up to the end of rearing period. The results from the mean comparison of coliforms in cecum in the day 42 indicated that experimental treatment was significantly different with control (p<0.05). The highest mean was concerned to control treatment and the lowest one was related to treatment which consumed 3% (DCSP) up to the end of rearing period and 1.5%(DCSP) to day 21.
