Values are presented as mean ± standard deviation.

BG blue lupin group, WG white lupin group, SG soya group; blue lupin, Lupinus angustifolius cv. Boregine; white lupin, Lupinus albus cv. Typ Top; soya, Glycine max cv. Hefeng; citrus, citrus fibre Herbacel AQ Plus serving as active comparator.

a>b>cSignificant differences between mean values within each group with unequal superscript letters (P ≤ 0.05) determined by repeated measures ANOVA.

WValues were not normally distributed; significance was calculated by means of the Wilcoxon test.
