SEM, standard error of the mean
a,bDifferent superscripts within a column indicate a significant difference (P < 0.05)
x,yDifferent superscripts within a column indicate a tendency difference (P < 0.1)
1Dietary treatment = additional Fysal Solute (FS) at 2 kg/ton
2V/C ratio = Villous length (μm) divided by Crypt depth (μm)
