BC-fed, piglets separated from the sow and fed bovine colostrum; MR-fed, piglets separated from the sow and fed a commercial milk replacer; Sow-Milk, piglets kept with the sow; Treat, treatment; Seg, segment of the small intestine; cfu, colony-forming units.

^a,bValues within a row with unlike superscript letters were significantly different (P≤ 0·05).

Four piglets were analysed per treatment (of each small-intestinal site, one segment was not inoculated and two segments were inoculated with Escherichia coli F18).

^†

Intestinal segments (collected from the treated piglets) were not inoculated with E. coli F18 during the porcine intestinal organ culture (PIOC) experiment.

^‡

Intestinal segments (collected from the treated piglets) were inoculated with E. coli F18 (8·96 (se 0·29) log colony-forming units/ml for each segment) during the PIOC experiment.
