¹Values represent least square means of four pens for the uninfected control group and six pens for the infected control and infected supplemented groups, sampling three pigs per pen. All pigs received allotted treatment diet starting at −7 DPI.

²Ileal mucosal scrapings used to determine total sIgA and total protein.

³Represented as the percentage of total cells in an ileal tissue cross section that stained positive for myeloperoxidase.

Abbreviations: DPI, days postinoculation; ETEC, enterotoxigenic E. coli; sIgA, secretory immunoglobulin A; MPO, myeloperoxidase.
