Figure 3.

(a,b) Venn diagram of shared OTUs of the different groups during the period of drug administration (2 weeks) and during the period of no drug administration (2 weeks), respectively. The numbers below the groups indicate the number of OTUs within each sector. (c) Heatmap showing the genera with significant differences in relative abundances among the seven groups. Partial least squares discriminant analysis (PlS-DA) among groups of control and antibiotic-exposed chicks. ENR-Ad: addition of enrofloxacin; ENR-Nd: no enrofloxacin; DEC-Ad: addition of diclazuril; DEC-Nd: no diclazuril; MIX-Ad: addition of drug mixture; MIX-Nd: no drug mixture; CON: control group.
