다국어 초록 (Multilingual Abstract)

This experiment was carried out to investigate the effect of slope exposure (north and south) and altitude (250m, 350m and 500m) on the grass quality in mountain pasture. The experiment was allocated as a randomized block design with 4 replications and was undertaken over a period of 20 months from February, 1986 to October, 1987. The results obtained are summarized as follows. 1. Dry matter yield of grasses in mountain pasture was higher on the northern slope than on the southern slope and was high in the following order, beginning with the altitudes least produced; 250m, 350m and 500m above the sea level. 2. Crude protein content of grasses was higher on the north slope than on the south slope, but NDF and ADF content showed the reverse trend. In-vitro dry matter digestibility was not different between the south and north slope. 3. Crude protein content of grasses was high as the altitude was high from 250m to 500m. Otherwise, NDF and ADF content and in-vitro dry matter digestibility was not different among the altitudes. 4. The yield of crude protein, NDF, ADF and in-vitro digestible dry matter was higher on the north slope than on the south slope and was high in the following order, beginning with the altitudes least produced; 250m, 350m and 500m.
