Abstract

This study aimed to determine enhancement of fermented oil palm trunk on ration complete on rumen degradability in vitro. The experiment was conducted using a Randomized Block Design (RBD) consisted of 4 treatments and 4 replication. The treatment provided were A: 30% of fermented oil palm trunk plus 70% concentrates; B: 40% of fermented oil palm trunk plus 60% concentrates; C: 50% of fermented oil palm trunk plus 50% concentrates; D: 60% of fermented oil palm trunk plus 40% concentrates, and the measured variables were chemical composition and rumen degradability in vitro such as dry matter (DM), organic matter (OM) digestibility, rumen fluid characteristics (pH, NH3, and VFA) as well as fiber fraction digestibility (NDF, ADF, cellulose). The results showed that the treatment significantly affected (P< 0.01) on the DM, OM digestibility, fiber fraction digestibility (NDF, ADF, cellulose), NH3 and VFA and did not significantly affect (P> 0.05) on pH. The finding indicated that the use of 40% of fermented oil palm trunk plus 60% concentrates yields the best rumen degradability with the following characteristics:DM and OM degradability: 67.39%, and 67.52 %, ADF, NDF and cellulose degradability : 43.03%, 54.13%, and 58.26% for ADF, NDF and cellulose. The rumen characteristic were: 6.89, 18.49 (mg/100), 98.75 (mM) for pH, NH3 and VFA, repectively.
