This study was conducted to compare the DM intake, the digestibility, and the utilization of nitrogen and energy of Korean native goats, when fed on orchardgrass supplemented with alfalfa or birdsfoot trefoil. Experimental diets included three treatments: orchardgrass(OG) 100%, orchardgrass 60%+alfalfa(AA) 40%(OG+AA), and orchardgrass 60%+birdsfoot trefoil(BT) 40%(OG+BT). The CP content was higher for OG+AA and OG+BT diets than for OG diets(P0.05). The NDF content was high in OG diets(P0.05) and the lignin content was high in OG+BT diets(P0.05), but the ADF content did not differ among all diets. The DM intake and the digestibility of DM and cellular constituents were higher for OG+AA diets than for OG diets(P0.05), but the NDF and ADF digestibility were not significant difference among all diets. The apparently digested N was higher for OG+AA diets than for other diets(P0.05). However, the retained N % and biological value were higher for OG+BT diets than for OG diets(P0.05), but those were not differ between OG+AA and OG+BT diets. On the other hand, the utilization of DE and ME did not show the difference among all diets.
