Combined analysis of cecal microbiota and broilers phenotypes. (A) Heatmap showing correlation analyses between muscle quality and lipid metabolism-related parameters and relative abundances of gut microbiota. Only the top 20 significant correlations are displayed. (B, E) Correlation of the relative abundances of Phascolarctobacterium (B) or Clostridium (E) with liver TG level and abdominal fat rate. (C, F) Correlation of the relative abundances of Phascolarctobacterium (C) or Clostridium (F) with chest muscle rate and chest muscle TG level. (D, G) Alterations of the relative abundances of Phascolarctobacterium (D) or Clostridium (G) in gut microbiota after ARE supplementation. All the results are shown as the means ± SD; *P < 0.05, **P < 0.01, ***P < 0.001 (n = 5).
