Metabolite profiles of fractional fecal excretion of fumonisins and their metabolites expressed as percentage of the sum of all toxins (means of n = 6/group) at 48 h post toxin application for group FUMpo (120 mg FB1 + 48 mg FB2 + 14 mg FB3/kg diet) and FumDpo (120 mg FB1 + 48 mg FB2 + 14 mg FB3/kg diet and 240 U fumonisin esterase per kg diet). (a) FB1 and metabolites (HFB1, pHFB1a, pHFB1b) with following main effects (F-test): pFB1 = 0.009, pHFB1 = 0.002; ppHFB1a = 0.0260; ppHFB1b = 0.026. (b) FB2 and metabolites (HFB2, pHFB2a, pHFB2b) with following main effects (F-test): pFB2 = 0.015, pHFB2 = 0.002; ppHFB2a = 0.240; ppHFB2b = 0.937. (c) FB3 and metabolites (HFB3, pHFB3a, pHFB3b) with following main effects (F-test): pFB3 = 0.015, pHFB3 = 0.065; ppHFB3a = 0.041; ppHFB3b = 0.093.
