Fig. 2From: Dietary supplementation of red-osier dogwood polyphenol extract changes the ileal microbiota structure and increases Lactobacillus in a pig modelKrona pie charts of ileal microbial compositions for the five sample in control group (A–E) and the five samples in ROD polyphenol extract group (F–J). The diagram shows different taxonomic levels of ileal microbial compositions including domain, phylum, class, order, family, genus and species from the center to the outside. The fan-shaped area corresponds to the relative abundance of corresponding microbesBack to article page
