Pig served as the experimental unit.

LS means within a row having differing superscripts are statistically different (P < 0.05).

Abbreviations: CON, control treatment (unsupplemented diet without infection); ISF, isoflavone-supplemented treatment (with infection); PND, postnatal day; POS, positive control (unsupplemented diet with infection); SEM, standard error of the mean.
