Ct, ND (non-detectable) considered negative, 0 < Ct≤ 38 considered positive, Ct > 38 considered suspect.

Pairwise P-value between POS and ISF treatments.

Gilt served as the experimental unit.

Abbreviations: CON, control treatment (unsupplemented diet without infection); Ct, cycle threshold; DPI, days post-inoculation; ISF, isoflavone-supplemented treatment (with infection); POS, positive control (unsupplemented diet with infection); SEM, standard error of the mean.
