The aim of this study was to evaluate the effect of adding nano-selenium and astaxanthin and their mixture to broiler rations on oxidation and immunity indicators. Unsexed Ross-308 broiler chicks were used. The results of the study showed that there was a significant (P≤ 0.05) decrease in the concentration of ALT enzyme in the treatments of T2 and T5 compared to the control treatment T1. Also, there was a significant decrease (P≤ 0.05) in the concentration of AST enzyme in the blood serum of the experimental treatments compared to the control treatment T1, and the two treatments T2 and T7 outperformed significantly (P≤ 0.05) in the concentration of glutathione peroxidase enzyme compared to the control treatment T1, and the increase in the concentration of catalase enzyme in the T6 treatment compared to the control treatment T1, while the concentration of malondehyde decreased in the experimental treatments compared to the control. There was a significant increase (P≤ 0.05) for treatment T4 and T7 in the weight bursa of Fabricia compared with the control treatment T1, as well as a significant increase (P≤ 0.05) in the value of the relative weight and index of bursa of Fabricia for treatments T7, T4, T2 when compared with the control treatment. T1 .There was a significant increase (p≤ 0.05) for treatment T3 and T6 in the volumetric criterion of antibodies to Kamboru disease when compared with the control treatment T1, while the volumetric ratio of antibodies to Newcastle disease decreased in all experiment treatments when compared with the control treatment T1.
