Abstract

Digestibility of fibre in ruminants may be improved by the introduction of highly fibrolytic strains of ruminal bacteria. This approach may be feasible if, for example, strains of that are significantly more fibrolytic than the normal population of are used for inoculation purposes. Introduced strains of bacteria, irrespective of ecosystem, often decline after inoculation, and in this study, highly fibrolytic strains of were continuously dosed to ensure that measurements of fibre digestion were made in the presence of significant numbers of the introduced bacteria. During dosing the total culturable count increased significantly (<005), but declined post-dosing. The level of dosed , and total , and eukaryotes measured by 16S rRNA probes increased significantly (<005) during the dosing period, but also declined post-dosing. When nylon bag digestibility, feed intake or whole-tract digestibility was measured, no improvement could be measured.
