Effects of dietary supplementation of LQ on composition of cecal microbiota and differential species identified at phylum, family and genus level of broilers on day 42. (A, C, E) were microbiota composition at phylum, family and genus level, respectively; (B, D, F) were the differential bacteria at phylum, family and genus level. Significant difference was recorded by 0.01 < P ≤ 0.05*, 0.001< P ≤ 0.01**.
