چکیده
To asses the effect of turmeric (Curcuma longa) supplementation on antioxidants and immunity of broiler chickens, seventy five run day old coloured synthetic broiler chicks were randomly divided into 3 groups (25 chicks per each) of mixed sex. Group I served as control (without any supplementation), whereas birds in groups II and III were supplemented with 0.5% and 1.0% Curcuma longa powder respectively and the trail was lasted for 7 weeks. Blood samples were collected at the end of the experiment to study the antioxidant enzyme status and immunity of birds. The results indicated that addition of Curcuma longa powder caused significant (P<0.05) increase in antioxidant enzyme status of birds. The cellular immune response of broiler birds to phytoheamagltinin-P and antibody titre to sheep red blood cells was significantly (P < 0.05) higher in treated group than unsupplemented control birds. The present results confirmed the beneficial effects of dietary Curcuma longa powder to improve antioxidant enzymes and immune status of broiler chickens.
