Abstract

This study was carried out to determine the dry matter (DM) and organic matter (OM) digestibilities, and metabolizable energy levels of some forages commonly used in ruminant nutrition by 2 different in vitro methods: the enzyme technique and the 2- stage method (rumen fluid + HCl-pepcine). Seven different samples of alfalfa hays, sainfoin hay and grass hay, and 4 different samples of wheat straws, lentil straw, corn silage and sorghum silage were used in the experiment.
