ABSTRACT
The effect of three different diets (100% fresh lucerne, Experiment I; fresh lucerne/
maize 60:40, Experiment II; fresh lucerne/maize 40:60, Experiment III) and fat sources
(linseed, rapeseed, fish oil, 5%wt·wt-1) on methane production was studied in vitro. In
experiment IV, 60% fresh lucerne+40% maize was supplemented with 5%wt·wt-1 of oil
blends. Methane production was significantly reduced (P < 0.05) mainly in the diet with
linseed and fish oils (24 and 23%, respectively; Experiment I). The control diet consisting
of fresh lucerne was characterized by the highest methane production (9.77 mMd-1) when
compared with the control diets rich in concentrate (4.75 mMd-1).
