    <p>This study was conducted to evaluate the effects of dietary supplementation of dried neem (<i>Azadirachta indica</i>) leaf extract (DNE) on lipid peroxidation and the expression of genes encoding mRNAs in antioxidant enzymes in the pectoralis major muscle of chickens. A total of 24 male broiler chickens (ROSS308) were divided into three groups (n = 8) at 21 days of age. The control group of chickens was fed a basal diet, and the remaining two groups of chickens were fed a basal diet supplemented with DNE at a concentration of 0.5% or 2.0% until 35 days of age. Growth performance (body weight, weight gain, feed intake, and feed conversion ratio) and tissue weights did not differ among the three groups. The 2.0% DNE-supplemented diet decreased the muscle malondialdehyde content, a marker of lipid peroxidation, and drip loss compared to the control chickens. In addition, the expression of genes encoding mRNAs of antioxidant enzymes (i.e., Cu/Zn-superoxide dismutase, Mn-superoxide dismutase, glutathione peroxidase 7, and catalase) were higher in the pectoralis major muscle of chickens fed the 2.0% DNE-supplemented diet than in the control chickens. Therefore, DNE supplementation increased the expression of genes encoding mRNAs in antioxidant enzymes and reduced lipid peroxidation and drip loss in the pectoralis major muscle of broiler chickens. </p>
