a,b Least square means within a row with different superscript significantly differ (p < 0.05). 1 Feces were collected from females and castrated males at 99 and 154 days of age, and from females only at 119 and 140 days of age. Half of the female pigs received a DON-contaminated diet between 113 and 119, and between 134 and 140 days of age. 2 Residual standard deviation from an ANOVA model accounting for the enterotype (E), the replicate (R), the initial body weight of the pig at 99 days of age (I), the sex (S), and the DON challenge (D). All the interactions have been tested and none are significant. 3 Significant effects (p < 0.05).
