^a,b Values within a column with unlike superscript letters differ significantly (P < 0.05)

¹ VH villus height, CD crypt depth, V/C villus height to crypt depth ratio

² NC negative control (broilers were free of challenge), PC positive control (broilers were challenged with S. Typhimurium from 7 to 9 d of age); AHLase, PC broilers supplemented with 10 U/g AHLase
