Correlation analysis of gut microbiota (A, at phyum level; B, at class level; C, at order level; D, at family level; E, at genus level) with serum diamine oxidase (DAO) activity and growth performance (BW, body weight; ADG, average daily gain) in broilers on d 10. The red and blue panes represent positive and negative correlations, respectively. Color intensity indicates the Spearman’s r-value of correlations in each panel. The asterisks indicate significant correlations (^∗P < 0.05; ^∗∗P < 0.01). NC, negative control (broilers were free of challenge); PC, positive control (broilers were challenged with S. Typhimurium); AHLase, PC broilers supplemented with 10 U/g AHLase
