Extract

The use of Indigestible Dry Matter (IDM) has been proposed to be used as internal marker to estimate digestibility (Milne, 1977, Kotb and Luckey, 1972), but information of reliability of this marker is limited.

The aim of this experiment was to study the effect of sward height and sampling period on Dry-Matter Digestibility of pasture (DMD), using IDM as internal marker.
