1 CON, control; CTC, chlorotetracycline (75 mg/kg); PB, probiotic (500 mg/kg in phase 1, 300 mg/kg in phase 2); SEM, standard error of the mean. 2 Treatment, the specific p value of the diet effect in the ANOVAs analysis. a,b values in the same row with different letters are significantly different at p < 0.05.
