In order to investigate feed values due to processing form of alfalfa, this study was carried out with 4 heads of sheep and Korean Native Cattle, respectively, for pellet, cube and hay of alfalfa imported in the year of 1984 and 1988. The results obtained were as follows; 1. Proximate composition Crude protein content was highest(24.66) in cube but lowest(17.60%) in pellet. crude fiber content was 29.0 and 17.82%, respectively, in pellet and cube, but NFE contents similar in all forms. 2. Cell wall constituent content ADF and NDF contents were 49.42 and 37.41%, respectively. in pellet but 31.15 and 22.03%, in cube. 3. Amino acid and mineral composition Contents of cystine and methioine were lowest in all forms. Ca, P and K were similar in all forms. Na content(%) was highest(0.45) in hay but lowest(0.05) in pellet. 4. Digestibility and digestible nutrientIn order to investigate feed values due to processing form of alfalfa, this study was carried out with 4 heads of sheep and Korean Native Cattle, respectively, for pellet, cube and hay of alfalfa imported in the year of 1984 and 1988. Digestibilities and nutrient values were high in cube. Dry mater digestibility and TDN value were 67.06 and 62.51%, respectively, in cube and 55.76 and 55.65% in pellet. 5. Because nutrient values of alfalfa are varied according to cutting stages and cultivating area such as above results, It is required to utilize alfalfa with evaluating exact feed components of alfalfa and considering feed cost between alfalfa and others.
