Identification of a previously uncharacterized Ruminococcaceae bacterial species associated with inclusion of high levels of lipid in the diet of beef steers

An abstract of a study by Hron et al evaluating ruminal microbial composition among 5 ruminally cannulated steers fed a corn-based diet with inclusion of 0, 4 or 8% added saturated (tallow) or unsaturated (linseed oil) lipids is presented. In 3 of the 5 steers, a single species-level Operational Tax...

Summary:An abstract of a study by Hron et al evaluating ruminal microbial composition among 5 ruminally cannulated steers fed a corn-based diet with inclusion of 0, 4 or 8% added saturated (tallow) or unsaturated (linseed oil) lipids is presented. In 3 of the 5 steers, a single species-level Operational Taxonomic Unit (OUT) was found in much greater abundance when diets included saturated or unsaturated lipids. This OTU was, in contrast, found in much lower abundance in controls classifier to the family Ruminococcaceae while database searches using BLAST revealed only one match (99%) to sequences of the NCBI "nt" database. To their knowledge, this is the first report of an OTU associated with greater lipid inclusion in diets to ruminants.
