Note. Growth parameters (initial body weight (IBW), final body weight (FBW), weight gain (WG), feed conversion ratio (FCR), specific growth rate (SGR), hepatosomatic index (HSI), survival, condition factor (CF), apparent digestibility coefficients of dry matter (ADCDM), and apparent digestibility coefficients of crude protein (ADCCP) were expressed as the mean ± standard error (n = 3). Different letters (a, b, c) in the same row represent significant differences (P < 0.05). Pr > F, significant probability associated with the F-statistic; ANOVA, analysis of variance.
