Effects of Zearalenone on 𝛼 and 𝛽 diversity of gut microbiota in laying hens. (A) Number of OTU, (BD) α diversity of gut bacteria based on Chao1 index (B), ACE index (C) and Shannon index (D), (E) PCA plot of β diversity on OTU level, (F) NMDS on OUT level based on bray curtis. *, p < 0.05, **, p < 0.01. Note: α diversity is a measure of how diverse an individual’s microbiome is. 𝛽 diversity is an indicator to characterize similarity in microbial composition between individuals.
