Results are mean ± SEM. Significant differences between all the different feed types were determine by one way ANOVA indicated by (*, P < 0.05). Post ANOVA Tukey's multiple comparisons test was done to comparing between the mean values for each of the different diets. Means with different letter of superscripts are significantly different, (Padj < 0.05). SEM = Standard Error of Mean; std = standard; SGR = specific growth rate; FCE = feed conversion efficiency. The formulae for SGR, FCR and Condition factor could be found in subsection 2.5 under Materials and Methods.
