Structural and functional analysis of the active cow rumen’s microbial community provides a catalogue of genes and microbes participating in the deconstruction of cardoon biomass

Table 1 In situ digestibility (g kg⁻¹ of initial weight), and chemical composition (g kg⁻¹, dry matters basis) of the residue and ruminal solids

¹Cardoon digestibility measured from biomass samples collected from nylon bags at 48 and 96 h incubation are reported in Additional file 1: Table S2
²The chemical composition of the rumen solid was measure at the end of the in situ experiment (see Fig. 1 for reference)
