Extract

The metabolisable protein system (AFRC, 1992) introduced the term Fermentable Metabolisable Energy (FME) as a measure of the amount of energy that was available in the rumen to support microbial activity. FME is currently derived from theoretical considerations rather than direct measurement; it is on based metabolisable energy (ME) but does not take into account rumen outflow rates and gives limited consideration to the chemical composition of feeds. Gas production from in vitro fermentation of feeds is an indicator of microbial activity which might be a suitable assessment of the rumen available energy content of feeds.
