The hatched chickens from each group were randomly assigned to four replicates of 12 chickens. All chickens were reared under similar managerial and hygienic conditions. The chickens were raised in clean, well-ventilated, previously disinfected room. The lighting schedule was 23 h light/1 h darkness at 32 °C on the 1st day. This was subsequently reduced 3 °C each week until the end of the third week then maintained at 23 °C. The chickens of different experimental groups were fed on basal diet (Table 1) to meet the nutrient requirement[15]. Mash diet and fresh water were offered ad libitum. Weight gain (WG) and feed intake (FI) were measured weekly and cumulatively and feed conversion ratio (FCR) was calculated accordingly.
