Effects of Supplementation with Dried Neem Leaf Extract on Lipid Peroxidation and Antioxidant Enzyme mRNA Expression in the Pectoralis Major Muscle of Broiler Chickens.

This study was conducted to evaluate the effects of dietary supplementation of dried neem () 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 (=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.
