Nutritive value, in vitro dry matter digestibility (IVDMD) and dry matter degradability (DMD) were evaluated in palm fruit, kernel, seed, palm fiber, palm shell and palm kernel meal (PKM). PKM had the highest (P0.01) protein, 12.28 percent and IVDMD, 64.92 percent. Palm shell had the lowest (P0.01) protein, IVDMD and DMD (2.99, 15.08 and 10.08 -17.19 percent) and the highest (P0.01) neutral detergent fiber (NDF) and acid detergent fiber (ADF). Fruit, kernel and seed had higher fat content and lower in IVDMD. Protein, NDF and ADF content in palm fiber were 7.08, 78.08 and 60.10 percent. Three fistulated steers (average BW 350 Kg) were given 0, 50 and 75 percent PKM in concentrate diet (14 % CP) in 3 * 3 Latin square design. All groups of cattle had similar (P0.05) of dry matter intake, ruminal total nitrogen, protein nitrogen, nonprotein nitrogen, soluble nitrogen, molar proportion of VFA and mineral content in serum. At 1 h postfeeding had the highest total nitrogen, nonprotein nitrogen and soluble nitrogen. Protein nitrogen was highest at 4-6 h postfeeding. Molar proportion of VFA as acetic, propionic and butyric acid was 62.54, 17.90 and 13.65 molar pecent. Mineral in serum was increased at 3 h postfeeding ; calcium, 12.21 mg percent ; phosphorus, 6.16 mg percent ; magnesium, 1.80 mg percent ; zine, 5.52 ppm and copper, 5.98 ppm.
