Values are expressed as the means ± SEs; different letters represent statistically significant differences (). IBW, initial body weight; FBW, final body weight; FR, feeding rate (%BW/d) = 100 × dry feed intake/[days × (IBW + FBW)/2]; SGR, specific growth rate (%/d) = 100 × [ln (final body weight)−ln (initial body weight)]/days; FE, feed efficiency (%) = (final body weight-initial body weight)/feed intake in dry matter; CF, condition factor (g/cm3) = 100 × (body weight)/(body length)3; VSI, viscerosomatic index (%) = 100 × (viscera weight)/(whole body weight).
