摘要：Gelam putih ( M. cajuputi Powell) in Central Kalimantan, has not been exploited well. In vitro test conducted to evaluate the potential of gelam leaves as cattle feed. The measured variables were NH3, volatile fatty acid s (VFA), dry matter Digestibility (DMD) and organic matter Digestibility (DMO). Completely randomized design was made with 5 different treatments and 4 replications, in order to get 20 experimental units. Data were analyzed by analysis of Variance (ANOVA) Followed by Duncan's multiple range test with a significance level of 5%. The results showed that the giving 100% of gelam leaves produced NH3 dan VFA for about 4.01 and 151.25 mM, also DMD and DMO by 58.35 and 52.38%. These results were significant (p<0.05), higher than the grass field, so it can be concluded that the waste of gelam leaves, potentially be used as cattle feed.
