The metabolic pathways involved in hydrogen production
and utilisation, as well as the methanogenic community are
important factors that should be considered when developing
strategies to control CH4 emissions by ruminants. Any given
strategy has to address one or more of the following goals:
> a reduction of hydrogen production that should be
achieved without impairing feed digestion;
> a stimulation of hydrogen utilisation towards pathways
producing alternative end products beneficial for the
animal; and/or
