¹n = 8 pigs/treatment.

²Sham = unchallenged; E. coli = E. coli challenged; CON = control diet; SMA = 0.3% smectite A; SMB = 0.3% smectite B; ZEO = 0.3% zeolite.

³E. coli = E. coli challenge effect; Diet = diet effect; E x D = interaction between E. coli and diet effects.

⁴Contrast between CON and all clay treatments within challenge treatments.

⁵Sulfo = % of total sulfo- and sialomucin area that is sulfamucin.

⁶Sialo = % of total sulfo- and sialomucin area that is sialomucin.
