  Background and Objective: The high level of oxidative stress (OS) is not only a compromise between welfare and health status but adversely affects survival, performance and the quality of final products. Antioxidants are defined as any substance which delays, prevents or removes overproduction of oxidative damage. The present study was conducted in order to investigate the efficacy of pomegranate peels (PPP) and black pepper (BPP) powders and their mixture added to diet of broiler chicks to alleviate the effect of oxidative stress. The stress is induced by H2O2 in drinking water. Materials and Methods: The sample encompassed 600 broiler chicks Ross 308. Birds were distributed randomly into the following 5 groups (4 replications in each): G1 (negative control) kept without any additives to feed or water, G2 (positive control) treated with 0.5% H2O2 additive to drinking water, G3-fed with 1% of PPP and 0.5% H2O2 additive to drinking water, G4-fed with 1% of BPP and 0.5% H2O2 additive to drinking water and G5-fed with 0.5% of PPP and 0.5% of BPP as well as 0.5% H2O2 additive to drinking water. The research was completed in the 6th week of birds’ life. The productive characteristics, carcass traits and oxidation state in blood plasma were evaluated. Results: The results revealed that G3, G4 and G5 recorded a significant increase in body weight, feed and water intake, protein and energy efficiency ratio, production efficiency factor, carcass yield and breast muscle proportions compared to G2. It was noted that feed conversion ratio decreased considerably in experimental groups compared to G2. Groups G3, G4 and G5 achieved a significant increase in SOD, GPx and FRAP and in the CAT level in plasma with a decrease (p<0.05) in LOOH and MDA value compared to G2. Conclusion: It was concluded that the supplementation of pomegranate peels and black pepper powders or their mixture in birds’ diet may alleviate the effect of oxidative stress by improving productive traits and oxidative parameters in blood plasma.
