Relative abundance of the main bacterial communities found in each groups in the rex rabbits caecum assigned at the genus level. a–d Control, chlortetracycline, colistin sulfate and zinc bacitracin main bacterial communities, respectively. The circle map consists of three layers, from inside to outside: the first layer is the phylogenetic tree constructed by OTUs representative sequence and the branches colors indicate the corresponding genus name and each color represents a genus; the second layer is the relative abundance distribution of OTUs, the height of column indicates that the relative abundance of OTUs (Owing to the relative abundance across a large amount of data, in accordance with the minimum value of transformation and visualization); the three layer is the credibility of the OTUs annotation distribution, and the height of column indicates the credibility of OTUs notes
