Since the publication of this paper, the authors have noticed an error in Figure 4. The correct figure is shown here.

Phylogeny and differential abundance and distribution of phylotypes in the family Erysipelotrichaceae among treatment groups. (a) Phylogeny of phylotypes in the family Erysipelotrichaceae. One sequence was randomly selected from each operational taxonomic unit (OTU) (97% identify threshold) and was inserted into pre-established phylogenetic trees of full-length 16S rRNA gene sequences in ARB. The tree shown here only includes some reference species of Firmicutes and the sequences from this study in the family Erysipelotrichaceae. These phylotypes fall into four lineages, M1–M4. The DGGE bands in M1–M4 are also shown. (b) Abundance distribution of M1, M2, M3 and M4 in the four groups of animals.

The authors would like to apologize for any inconvenience this may have caused.
