The effect of Curcumin on growth performance, blood biochemistry and antioxidant activities in boiler chickens

Abstract

The antioxidant effects of Curcumin that extracted from Curcuma longa not only reduce free radical but also improve growth performances in broilers. A study was conducted to investigate the effects of Curcumin on blood biochemistry parameters and antioxidant status of broilers exposed to varies of raising systems. The 180 boilers were randomly assigned into 6 categories compose of 3 raising systems; semi-intensive and stocking densities of 10 and 16 birds/m2 in each group fed with control diet mixed with and without 10% Curcumin. The result show that the activities of antioxidant systems, lipid peroxidation were gradually increased in highest stocking density (16 birds/m2 ). However, the level of lipid peroxidation was reduced while, catalase and superoxide dismutase activities were significantly increased in blood chickens as also the growth performances and blood biochemistry that improved after fed with 10% Curcumin. This finding indicates that Curcumin has potentiated to reducing the oxidative stress, activated antioxidant enzyme activities and improve the growth performance of broilers raised under stress condition.
