Thirty-two female Ross 308 hybrid broilers were fed one of four diets supplemented with 0%, 0.1%, 0.05% and 0.025% of Cinnamomum zeylanicum essential oil for 38 days in order to investigate the effects of this feed supplement on the antioxidant status of chickens. Blood, liver, kidney and duodenal epithelium were collected for the subsequent evaluation of antioxidant status. Feeding of the diet supplemented with 0.1% of essential oil significantly decreased the concentration of malondialdehyde in plasma and duodenal mucosa. The activities of glutathione peroxidase were significantly higher in blood of chicks fed the diet containing 0.1% of essential oil. Diets containing 0.05% and 0.025% of essential oil reduced alanine aminotransferase activity in plasma in comparison with the control group. Blood phagocytic activity significantly increased in chickens fed the diet supplemented with 0.1% and the index of phagocytic activity was affected by the diet containing 0.025% of essential oil in comparison with the control group. The present investigation shows that Cinnamomum zeylanicum essential oil exhibits a significant antioxidant activity in fattening chickens.
