¹V/C = Villus height / Crypt depth
²CON = nonchallenge control, SCC = Salmonella-challenged control, O1 = S. pullorum challenge fed the basal diet plus 50 mg/kg ORI; O2 = S. pullorum challenge fed the basal diet plus 80 mg/kg ORI, O3 = S. pullorum challenge fed the basal diet plus 100 mg/kg ORI
³SEM = standard error of mean
^4,a,bValues within a row not sharing the same superscript are different at P < 0.05; n = 6
