Experimental design:
The experimental day old chicks were divided into 4 groups. Each group consisting of 40 chicks was designated as group A, B, C and D. Each group was divided into 4 replicates. Checks in group A were fed basal diet , while group B, C, and D were fed basal diet supplemented with 0.25, 0.5, and 1% Turmeric (Curcuma longa) during five weeks experimental period. Weekly feed consumption for each group was determined. Mean initial and weekly body weight of birds for each group was determined and then body weight gain was calculated.
