Determination of short-chain fatty acids (SCFAs) in cecal contents. (A) The exact amount of SCFAs in cecal contents, including acetic, propanoic, butanoic, isobutyric, valeric, isovaleric, hexanoic and isohexanoic acids, as detected by GC–MS method. (B) Heatmap showing Spearman’ correlation coefficient with p < 0.05 between several significant changed fecal SCFA and genera bacteria. Red cells represent positive correlation and blue cells represent negative correlation. Data are expressed as mean ± SD. ^#p< 0.05, ^##p < 0.01, ^###p < 0.001 compared with NC group; ^*p < 0.05, ^**p < 0.01, ^***p < 0.001 compared with MC group.
