The digestible experiments using swine were carried out to make up $quot;the Composition of Korean Feedstuffs$quot; published in 1981. The results obtained are as follows; DCP and DE value of wheat shorts were slightly higher than those of the Composition of Korean Feedstuffs (1981). TDN value, however, was lower resulting from low crude fiber digestibility. DE value of naked milled barley and milled barley were superior to that of the Composition of Korean Feedstuffs (1981) and NRC (1979), respectively. Campared between species of rapeseed meal, DCP and TDN value of Yeong San were higher than those of Yudal. It was also found that nutrient digestibilities, DCP, and TDN of alfalfa pellet was lower than those of the Composition of Korean Feedstuffs (1981).
