A number of studies have been conducted to evaluate the effects of curcumin on the performance of broiler chickens (Suriya et al., 2012; Nayaka et al., 2013; Abou-Elkhair et al.,2014; Olukosi and Dono, 2014); however, the results of these studies have been inconsistent. Keeping in view of the medicinal attributes of C. longa, the purpose of the present study was to evaluate the effects of increasing levels of turmeric rhizome extract (TRE) on performance, carcass characteristics, antioxidant capability, and meat quality of Wenchang broiler chickens.
