This syudy was conducted to increase the utility of forage rye which are suitable to be cultivated at high altitude Taekwllyong area. For that purpose two cultivars of rye (winter-more, kool-glazer) were cultivated for 3years using a randomized block design with 3 replications. The dry matter digestibility (DMD) was evaluated with the pelleted rye hay produced by adding sodium hydroxide and then the TDN value was calculated by the DMD. By adding NaOH, DMD and TDN value of rye pellets (Y=46.92+ 1.8X, ~ 0 . 9 7 )w ere increased significantly (p<0.05) and NDF (neutral detergent fiber) decrease significantly. However, ADF (acid detergent fiber) and lignin did not significantly decrease (p<0.05). Rye could be cultivated as a second crop after com at high altitude area in the same year and pelleted with NaOH in order to increase the nutritive values (p< 0.05).
