[Relative contribution of rumen bacteria, free and fixed to particles, on bacterial flow into the duodenum in the dairy cow].
Mean duodenal flow of bacterial DM (5130 +/- 358 g/d) represented 60% of total duodenal DM flow in dairy cows fed hay and concentrate (50/50). Contribution of solid-adherent bacteria (SAB) to the total bacteria entering the small intestine amounted to 71%. It must be taken into account in the estimation of the duodenal flow of bacterial compounds.
