Extract

Values for crude protein (CP) and ruminally undegradable CP content are now required in feed evaluation systems currently used in North America (NRC,1989) and other organizations (Ørskov,1992).The objectives of the present study were to assess in situ ruminal degradability, fractional rates of digestion and the effective degradability of the dry matter (DM) and crude protein (CP) of alfalfa and red clover hays, selected randomly from dairy farms of Tabriz region in Iran on the male sheep rumen.
