Objective of this study was to determine the degradability in the rumen and digestibility in the intestine of untreated oil palm fronds (OPF), chopped and steamed (CSOPF), and pelleted and steamed (PSOPF) using nylon bag and mobile bag techniques. Three cattle with an average weight of 314+-14 kg each fitted with a permanent rumen and a T-shaped duodenum cannulae were used. The cattle were fed a maintenance diet (1.5 percent DM of their BW) composed of 70 percent pelleted OPF and 30 percent concentrate. The potential degradation of DM, OM, NDF and CP of CSOPF (70.20 percent, 52.00 percent and 57.70 percent, respectively) and PSOPF (71.60 percent, 73.6 percent, 56.00 percent and 57.80 percent, respectively) were significantly higher (p0.05) than those of the untreated OPF (48.70 percent, 52.30 percent, 43.80 percent and 52.60 percent, respectively). Similarly, NDF disappearances of the ruminal undegraded (incubated in the rumen for 24 and 48 hr) matterials in the small intestine for CSOPF (7.40 percent and 7.16 percent, respectively), and PSOPF (7.24 percent and 7.14 percent, respectively) were significantly higher (p0.05) than those of untreated OPF (6.51 percent and 6.27 percent, respectively). However, DM and OM disappearances of the ruminal undegraded materials in the small intestine of all kinds of OPF were not significantly different (p0.05).
