MPO concentration in intestinal contents (µU/mL; d 7 postinoculation) of Salmonella-inoculated pigs¹

Item	FAA−	FAA+0	FAA+1	FAA+2	SEM	P-value
Ileum	4.51	4.88	5.01	4.52	1.03	0.98
Cecum	6.15	3.13	3.07	2.71	1.08	0.07
Colon	5.04a	3.83a	1.95b	1.93b	0.92	0.04

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 with different superscripts differ (P ≤ 0.05).
