Mean ± SD in the same line with different superscript letters differ significantly (P < 0.05). ¹Each mean represents six birds. 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. Results show the colony counts of SE in different organs, they are expressed as mean (Log₁₀ CFU/g of organ) ± SD. ²The days after challenging.
