Means within the same row without a common superscript differ significantly (P < 0.05); A: uninfected and untreated control; D: infected and untreated control; E: infected birds fed basal diet supplemented with 250 mg/kg bacitracin methylene disalicylate (BMD, 15% purity) plus 90 mg/kg monensin; F: infected birds fed basal diet supplemented with 200 mg/kg EOA; G: infected birds fed basal diet supplemented with 500 mg/kg EOA; H: infected birds fed basal diet supplemented with 800 mg/kg EOA.
SEM, standard error of the mean.
P-values represent the interaction between the dietary treatments.
VH/CD = villus height to crypt depth ratio
GC cells = goblet cells numbers per mm2.
