Abstract
This study was conducted to evaluate antioxidant activity of Cinnamon and Thyme and its relationship to quails egg and meat production performance. 100 quails were fed five diets: G1: control, G2: control diet + 1% of Thymus powder, G3: control diet + 2% of Thymus powder, G4: control diet + 1% of Cinnamon, and G5: control diet + 2% of Cinnamon. A complete randomized design (CRD) with 5 treatments, 3 replicates and 4 birds in each replicate was used. Live weight, egg production, feed intake, and egg production conversion ratio were determined. After blood sampling, Nitric oxide and TBARS values were evaluated. The results indicated that G2 group had highest level and G3 and G5 groups had lowest level of live weight. Quails in the G4 group had significantly higher feed intake (P
