Diet-dependent shifts in ruminal butyrate-producing bacteria

The influence of a host's diet on Butyrivibrio and Pseudobutyrivibrio populations was investigateded by competitive PCR. Specific primers were designed and competitive PCRs developed for both groups. Results (from 4 cows with different diets) suggested that high-fiber intake essentially increas...

Zusammenfassung:	The influence of a host's diet on Butyrivibrio and Pseudobutyrivibrio populations was investigateded by competitive PCR. Specific primers were designed and competitive PCRs developed for both groups. Results (from 4 cows with different diets) suggested that high-fiber intake essentially increases the Butyrivibrio amounts in the rumen, whereas high-energy food additives lead to its suppression. The Pseudobutyrivibrio concetration also changed during the experiment but without any significant relation to the host's diet.
