This experiment was performed to investigate the effect of different levels of aqueous and alcoholic extracts of Capparis Spinosa fruit on growth performance, blood biochemical indices, and immune system of broiler. 450 one-day-old broiler chickens of Ross were allotted in a completely randomized design with 9 treatments, 5 replicates and 10 birds in each replication. Dietary treatments were involved control and four levels 150, 300, 450 and 600 of aqueous extracts and four levels of 150, 300, 450 and 600 alcoholic extracts of Capparis Spinosa fruit. The chicks were fed with three dietary phases including starter (1 to 10 days), grower (11 to 24 days) and finisher (25 to 42 days). At 42 days, two chicks were selected from each replicate and sacrificed, and blood samples were taken to determine the concentration of total protein, uric acid, cholesterol, triglycerides, and HDL. The results showed that different levels of Capparis Spinosa fruit extracts affected the feed intake and conversion ratio of the whole experimental period (1 to 42 days). Although there was no difference in the starter and grower periods, but in the finisher period, Capparis Spinosa fruit extracts reduced feed intake and feed conversion ratio compared to the control (P <0.05). Supplementation of aqueous and alcoholic extract of Capparis Spinosa fruit extract reduced the blood concentration of cholesterol, triglyceride on broilers compared to the control. the addition of aqueous and alcoholic extract of Capparis Spinosa fruit reduced the activity of liver enzymes in broiler,
