  1. IBW = initial body weight; FBW = final body weight; WG = weight gain; SGR = specific growth rate; FI = feed intake; FCR = feed conversion ratio; HIS = hepatosomatic index; VSI = viscerasomatic index; CF = condition factor; SI = spleen index; IFI = intraperitoneal fat index and RGL = relative gut length.
  2. Data are means ± SE. Means with different letters, within row, indicate statistical significant difference at P < 0.05, followed by Dunnett’s multiple comparisons test.
