EOA = coated essential oil and organic mixture; VH:CD ratio = the villus height to crypt depth ratio; GC cells = goblet cell numbers per mm2; SEM = standard error of the mean.

a, b Means within the same column with different superscripts differ significantly (P < 0.05).

“–”, without E. coli O78 challenge; “+”, with E. coli O78 challenge.

2

P-values represent the main effect of the diet, the main effect of E. coli O78 challenge, and the interaction between the dietary treatments and E. coli O78 challenge.
