The effects of inorganic and organic Zn, Cu and Mo supplementation to the in vitro digestibility of Elephant grass were studied in this trial. The in vitro trial used the TILLEY dan TERRY method modified by VAN SOEST with the incubation of the grass for 48 hours in sheep rumen liquor medium. Mineral added as fonn of organic and inorganic. The treatment of mineral inorganic supplementations were by adding single e1emen Cu, Zn and Mo and its combination. Mineral added was Zn (as chloride and sulphate salts) 5 ppm, Cu (sulphate salt) 0,1 ppm dan Mo (molybdate salt) 5 ppm, with 4 replicates. Meanwhile the organic minerals added were in the proteinate fonns. Parameter measured were in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), pH, VF A total and NH3. Statistical analysis was done by using Complete Split splitsplot design. The supplementation increased pH value, VFA total, IVDMD and IVOMD value (P<0,05) and decreased NH3 value. The highest IVDMD and IVOMD values obtained at the mixture supplementation of mineral Zn (as Zn S04), Cu and Mo, from 58,31 became 69.73% and 52.22 became 62.55% respectively for IVDMD and NOMD. pH value increased from 6.48 to 7.05 and ammonia content decreased from 1,17 to 0,14%. The organic mineral supplementation, en-proteinate dan Zn-proteinate showed that the adding of Zn, Zn and Mo, Zn and Cu also the combination of Zn, Cu and Mo, resulted in IVDMD values as 70.29; 69.97, 64.12 and 63.93%. Further more IVDMD value at the supplementation of Cu and the combination of Cu and Mo were 65.08 and 60,49%. It can be concluded that the supplementation of minerals in the form of inorganic or organicÂ couldimprove the IVDMD values Key words: Three element, in vitro digestibility, sheep

A series of experiment was designed in order to improve the nutritive value of palm oil sludge (POS) through fermentation. POS was fermented in a fermentor chamber with different temperatures (28 and 32oC) and initial moisture content of the substrate (50,55 and 60%). The nutrient content (crude protein, true protein, in vitro- dry matter and protein digestibility and crude fibre) of the fermented products were evaluated at different stages of the fermentation, i.e.: before incubated (F0), 3 d after aerobic incubation (F3) and 2 d anaerobic incubation after F3 (EN). Cellulase and mannanase activity of the EN products were also measured before and after dried at 60oC. Fermentation at 32oC produced better product (higher nutritive values), although the in vitro dry matter digestibility was not affected by the temperatures. All parameters measured were not significantly influenced by the initial moisture content of the substrate. The nutritive value of unincubated POS (F0) was significantly poorer than the F3 and EN and there was no different in nutrient value between F3 and EN. Soluble nitrogen and in vitro dry matter digestibility were not significantly affected by the stages of the fermentation. Mannanase activity in the EN product was significantly higher when the fermentation was performed at 32oC than those at 28oC and the enzyme activity was reduced after dried (320.7 vs 201.8 U/g DM). The cellulase activity of the fresh/wet fermented product produced at 28oC was significantly higher than those produced at 32oC, but the reverse was occurred in the dry products. It is concluded that fermentation process of palm oil sludge at 32oC and initial moisture content of 50-60% produced better (in vitro) nutritive value.

An experiment was conducted to improve the nutritive value of palm oil sludge (POS) by fermentation process. Aspergillus niger BPT and NRRL 337 were used into fermenting POS for three days and followed by anaerobic enzymatic process. The experiment was arranged in 2x3 factorial design i.e., enzymatic incubation time (2, 3, and 4 days) and environmental temperature during enzymatic process (room temperature and 40Â°C). Changes on chemical compositions (crude protein, true protein, ADF and NDF), in vitro dry matter digestibility (IVDMD) and protein digestibility (IVPD) were measured. The results showed that both A. niger BPT and NRRL 337 grew well on POS media with the best result at 3 days. The fermentation process by both strains increased crude protein and true protein of POS. The A. niger NRRL reduced the fiber content (ADF and NDF) more than A. niger BPT the IVDMD and IVPD were not significantly affected by fermentation process without enzymatic process. The IVDMD increased significantly when the fermentation followed by enzymatic process. Overall results showed that the best fermentation of POS was obtained by using A. niger NRRL followed by enzymatic process in room temperature for two days.
