Extruded flaxseed (25%) and ground hay (75%) were each fed (DM basis) either together in a total mixed ration (TMR) or as flaxseed first followed by hay (non-TMR) to three pens of eight crossbred steers ( n  = 24 per diet) for 240 days. Compared to TMR, feeding non-TMR enriched subcutaneous fat with α-linolenic acid (ALA, 18:3n-3) and its biohydrogenation intermediates including vaccenic acid [ trans ( t )11-18:1], rumenic acid [ cis ( c )9, t 11-conjugated linoleic acid] and conjugated linolenic acid (CLnA). Rumen microbial analysis using QIIME indicated that 14 genera differed ( P  ≤ 0.05) between TMR and the non-TMR.  Azoarcus  and  Streptococcus  were the only genera which increased in relative abundance in the TMR fed steers, whereas  Methanimicrococcus, Moryella, Prevotella, Succiniclasticum, Succinivibrio, Suttenella , and  TG5  decreased as compared to steers fed the non-TMR. Among these,  Moryella, Succiniclasticum , and  Succinivibrio , spp. were correlated with fatty acid profiles, specifically intermediates believed to be components of the major biohydrogenation pathway for ALA (i.e.,  t 11,  c 15-18:2,  c 9,  t 11,  c 15-18:3, and total CLnA). In addition, negative correlations were found between the less abundant  Ruminoccocus- like OTU60 and major ALA biohydrogenation intermediates, as well as positive correlations with several intermediates from alternative pathways that did not involve the formation of  trans  11 double bonds. The present results suggest a number of pathways for ALA biohydrogenation are operating concurrently in the rumen, with their balance being influenced by diet and driven by less abundant species rather than members of the core bacterial population.
