Using three heads of sheep for each feedstuff the digestibilites of general compositions in domestic feedstuffs were determined through total collection method. The tested concentrates were fed together with a roughage, of which the digestible nutrients were known in a separate trial. The roughages were fed as a single diet. The minerals and water were provided ad libitum. The tested feedstuffs were; yellowcorn, immature rice, wheat grain, wheat flour, immature barley, naked barley grain, rye grain, soy bean, corn bran, perilla oil meal, linseed oil meal, cocount oil meal, corn starch cake, corn gluten, potato tubers, soy hull, orchard grass hay, mixed pasture grass hay, three kinds of native grass hays, and malt root. The general compositions in tested feedstuffs were expressed on table 1, and their digestibilities and digestible nutrients were recorded on table 3. Some of the tested feedstuffs showed lower values than those published abroad. One of the reasons was thought due to the higher crude fiber content of domestic feedstuffs when compared to foreign data. The other feeds represented similar results to the foreign one. It was thought that, in order to get accurate and representative values in Korea, more replicative experiments should be carried out in the future.
