Abstract :

An experiment was conducted to evaluate the eff ects of methanolic extract of Caesalpinia sappan supplementation on the antioxidant status and growth performance of broiler chicken during summer months. 100 days old broiler chicks were randomly assigned into 5 groups. Control group I was given basal diet and treatment groups II, III and IV were supplemented with methanolic extract of Caesalpinia sappan stem bark at 100, 300 and 500 ppm respectively and group V was supplemented with vitamin E at 100 ppm as an antioxidant control through drinking water from day 0 to 8 weeks of age. All the C. sappan supplemented groups showed signifi cantly lowered levels of malondialdehyde (MDA) and higher levels of reduced glutathione, GPx, SOD and catalase in liver and kidney tissues as compared to control. Th e serum levels of ALT, AST, CK and cholesterol were signifi cantly lower in treatment groups III and IV when compared with control. However, serum T3 levels showed no signifi cant change among diff erent groups. Groups IV and III showed higher weekly feed intake, body weight gain and feed conversion ratio compared to control group. Higher dressing yields and abdominal fat percentages were observed in group IV compared to control. It could be concluded that, supplementation of C. sappan extract improved antioxidant status and growth performance in broiler chicken and can be considered as a replacement for synthetic antioxidant in poultry diet in heat stress conditions.
