1Values are least squares means; n = 8 pigs/treatment. FAA−, pigs fed a basal AA profile throughout the experimental period. FAA+0, pigs fed a functional AA profile (FAA+; Thr, Met, and Trp at 120% of requirements) postinoculation. FAA+1, pigs fed FAA+ for 1 wk pre- and postinoculation. FAA+2, pigs fed FAA+ throughout the experimental period. SEM, Standard error of the mean.
a–bMeans within a row (trt comparison) or column (d comparison) with different superscripts differ (P ≤ 0.05).
