Extract

The UK metabolisable protein system proposed an approach for calculating the energy (termed fermentable metabolisable energy) available for rumen microbial protein synthesis. This approach does not take into account rumen undegradable organic matter (OM; mainly protein and starch) and ignores the dynamic aspects of the value, such as rate of fermentation. The aim was to evaluate three techniques to estimate OM apparently degraded in the rumen (OMADR) of different forages.
