Apparent absorption rates are mean values over 45 min, see Results; f, fractional absorption; AE*, assimilation efficiency

Values are means ± s.e.m., N=8 for all values. Pvalues were obtained by ANOVA, repeated measures ANOVA and paired and independent t-tests, with a significance level of α<0.05. Significant P values are shown in bold text
