An in vitro rumen incubation was used to evaluate the effects on nutritive value of
replacing Para gross with Paspalum grass at levels of 0, 25, 50 and 100% (DM basis).
Replacing Para grass with Paspalum grass resulted in linear increases in degradability
of DM and OM with corresponding decreases in methane production.
The reduction in methane as substrate degradability was increased supports the
conclusion that increasing the nutritive value of ruminant diets is one of the most
effective ways of reducing methane emissions from the livestock sector.
