<p>The apparent microbial community structure in parallel samples collected from 14 cattle using an oral stomach tube or through a rumen fistula was compared. The means (% of total community) and standard errors of the relative contribution of each microbial group are shown. The keys to the right indicate the major community components. The underlying data for bacteria, archaea, fungi and ciliate protozoa are provided in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0074787#pone.0074787.s008" target="_blank">Table S7</a>. <i>Mbb</i>, <i>Methanobrevibacter</i>. Differences between rumen sampling methods were assessed using dependent sample <i>t</i>-tests.</p
