Mean ± SD in the same row with different superscript letters differ significantly (P < 0.05). ¹Each mean represents six birds. NC, birds fed a basal diet without challenged with SE; PC, birds fed a basal diet and challenged with SE; EXP, birds fed a basal diet with C. butyricum (10⁶ CFU/mL) and challenged with SE. ²The days after challenging.
