^a,b,cMean value within a role with no common superscript differ significantly (P < 0.05). NC, control diet; IC, control diet + Eimeria infection; P8L, control diet containing 1 × 10⁷ cfu/g P8 + Eimeria infection; P8H, control diet containing 1 × 10⁸ cfu/g P8 + Eimeria infection; DIC, control diet + Eimeria infection + Diclazuril.
