Data are presented as means ± SEM. The data presented are obtained from 12 animals in each group (n = 12). In the same row, values with * were significantly different from NBW pigs at P < 0.05 and values with ** were significantly different at P < 0.01. ADG, average daily gain; ADFI, average daily feed intake; BW, body weight; F/G, feed/gain; Initial BW, body weight at birth; NBW, normal born weight
