^aAverage of data for the two cow samples are shown.

^bThe abundance refers to the proportion of hemicellulase-related reads in the total non-rRNAs. Only organisms with hemicellulase-related reads with an abundance of ≥0.001% are shown.

^cThe relative ratio refers to the proportion of the number of hemicellulase-related reads in a given organism in the total number of hemicellulase-related reads.

^dSimilarities of proteins encoded by transcripts to that of known hemicellulases from a given organism at the amino acid sequence level are shown.
