DM = dry matter; SEM = standard error of the mean.
∗,∗∗ indicate treatment means which differ significantly P < 0.10 and P < 0.05, respectively from the control mean; analysed according to the posthoc Dunnett's test.
a,b Means having different superscripts in a particular column for the main effect are significantly different; analysed according to the posthoc Tukey's HSD test (P < 0.05). Means are represented as means ± SEM.
CTRL, control diet; Bel, Belfeed supplemented diet; Eco, Econase supplemented diet. Reported values are means from 5 replicates from each dietary treatment group (n = 5).
