Note: IBW = initial body weight; FBW = final body weight; WG = weight gain; SGR = specific growth rate; FCR = feed conversion ratio; CF = condition factor; VSI = visceral somatic index; and HSI = hepatosomatic index. POV600 (600 meq·kg⁻¹ OFO diet), POV800 (800 meq·kg⁻¹ OFO diet), AP (POV600 group supplemented with 0.5% apple polyphenols), and TA (POV800 group supplemented with 0.2% taurine). In the same row, indicates that the POV600 and POV800 groups are significantly different from the Control group and ^#indicates that the AP group is significantly different from the POV600 group ().
