Phylogenetic analysis of methanogen partial mcrA sequences from finishing pig clone libraries inferred using MEGA (ver. 7). Evolutionary distances were calculated using the Neighbour-joining method. The tree was bootstrap resampled 1000 times.The 219 clones examined were assigned to 43 OTUs by DOTUR using a 97% species-level identity
