Fig. 1From: Rumen metagenome and metatranscriptome analyses of low methane yield sheep reveals a Sharpea-enriched microbiome characterised by lactic acid formation and utilisationConcentrations of major (a) and minor (b) fermentation acids in rumen content samples from LMY and HMY sheep. Fermentation acids were determined by GC-MS after derivatisation and normalisation to an ethyl butyrate internal standard, and concentrations shown are in millimolar. **P < 0.01. Green bars represent LMY (n = 8), and orange bars HMY samples (n = 8)Back to article page
