Analysis of the microbial community in relation to rumen fermentation variables and forage degradation. A Canonical correlation analysis. The top 10 most differentially abundant genera are indicated by triangle arrows with dashed lines, and the rumen fermentation variables and degradation of forage components are indicated by triangle arrows with solid lines. The samples collected at different time points and from different rumen environmental conditions are presented in various colors and shapes. B Spearman correlations of the differentially abundant genera and fermentation parameters. The columns represent the rumen fermentation variables and forage degradation efficiency, and the rows correspond to the genera significantly affected by the rumen environmental conditions and forage types. Gradient colors indicate the correlation coefficients. Genera were clustered according to the Euclidean distances calculated based on the correlation coefficients. C Spearman correlation of differentially abundant genera and Orskov’s fractions. Columns represent Orskov’s fractions of forage components, and rows correspond to the differentially abundant genera. The gradient colors indicate the correlation coefficients. Genera were clustered according to the Euclidean distances calculated based on the correlation coefficients
