Note. Data are presented as means ± SEM (n = 3). WG = weight gain; SGR = specific growth rate; FCR = feed conversion ratio; VSI = viserosomatic index; and HIS = hepatosomatic index. Means in the same row sharing the same or no superscript letters are not significantly different. Means with different letters indicate significant differences in the treatments ().
