The change on the chemical component and digestibility of dry matter was determined in wild grasses(Digitaria sanguinalis, Agropyron tsukushienes, Miscanthus sinensis, Carex humilis, Arundinella hirta, Spodiopogon sibiricus, Setaria viridis) and sild legumes(Vicia angustifolia, Cassia minosoides) by advanced stag of maturity grown in mountainous kyungnam area. Samples were dried at 70℃ for 24hr. and ground to pass a 1mm screen. They were subjected to the dtermination of the crude Protein(N×6.25), crude ash, neutural detergent fiber(NDF), acid detergent fiber(ADF), acid detergent lignin(ADL), and dry matter digestibility(DMD) by pepsin-cellulase technique. The energy values(total digestible nutrients. TDN : digestible energy, DE : metabolizable energy, ME) were calculated by DMD of pepsin-cellulase technique. The results obtained were as follows : 1. The curde protein of wild grasses and legumes were ranged from 4.79% to 13.22% and 20.24%-23.84%, respectively, and the crude protein had a tendency to decrease by advanced stage of maturity(P<0.05). 2. The curde ash of wild grasses and legumes were ranged from 5.34% to 11.24% and 5.97%-6.70%, respectively, and the crude ash was not changed by advanced stage of maturity. 3. The NDF of wild grasses and legumes were ranged from 63.43% to 89.30% and 45.11%-66.07%, respectively, and the NDF was increased by advanced stage of maturity(P<0.05). 4. The ADF of wild grasses and legumes were ranged from 37.41% to 50.29% and 35.14%-40.67%, respectively, and the ADF was increased stage of maturity(P<0.05). 5. The ADL of wild grasses and legumes were ranged from 7.19% to 15.59% and 9.30%-12.50%, respectively, and the ADL was increased by advanced stage of maturity(P<0.05). 6. The DMD of wild grasses and legumes were ranged from 23.05% to 54.71% and 45.52%-59.68%, respectively, and the DMD was decreased by advanced stage of maturity(P<0.05). 7. The calculated energy(TDN, DE, and ME) values of wild grasses and legumes were decreased by advanced stage of maturity. 8. Regression equation and correlation coefficients of wild grasses between DMD(Y) and crude protein content(X) were Y=17.2X+2.41×and r=0.710(P<0.01), respectively. 9. Regression equation and correlation coefficients of wild legumes between DMD(Y) and ADL(X) were Y=59.0-+2.61×and r=0.520(P<0.01), respectively.
