chemical composition, ruminal dry matter, crude protein andcell wall degradation kinetics of pasture forages dominant in the west provinces of iran

the objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (dm), crude protein (cp), neutral detergent fiber (ndf) and acid detergent fiber (adf) of ten pasture forage species dominant in the west provinces of iran. duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. the chemical composition of forages varied from 54 to 212 g/kg dm for cp, 239 to 638 g/kg dm for ndf, 190 to 378 g/kg dm for adf and 60 to 108 g/kg dm for ash. the effective dm degradability at rumen outflow rate of 0.05/h was different (p
