^a,bMeans in the same row without common superscripts differ significantly (P < 0.05). Data were presented as mean ± standard error. CTR, control group; CCP, the infection model group that was challenged with Clostridium perfringens and coccidia; CCP+ LF, the infection model group with Lactobacillus fermentum supplemented in the diet; and CCP+ LP, the infection model group with Lactobacillus paracasei supplemented in the diet.
