^a−cMeans within a row with different letters differ significantly (p < 0.05).

¹Data are means for 8 replicates of 6 birds per replicate. No birds died during the experimental period. The data in each group was expressed as mean with their standard errors (n = 8).

²ADFI, average daily feed intake; ADG, average daily gain; F/G, feed/gain; BW, body weight.
