Correlation analysis between insulin sensitivity, plasma serotonin concentration, and bacterial abundances. (A) Correlation analysis between insulin sensitivity index and plasma serotonin concentration; (B) Correlation analysis between the differential genera and plasma serotonin concentration. LF sows fed a basal diet, HF sows fed with the basal diet added with extra 22.60 g/kg inulin and 181.60 g/kg cellulose. n = 6 per group. The level of statistical significance was set by *P < 0.05 and **P < 0.01
