Abstract. The present study was conducted to evaluate a change in the chemical composition of layer faeces when it was fermented with commercial effective microorganisms (EM4). The experiment involved six treatment groups in which layer faeces were fermented with 0 ml (P0), 1.2 ml (P1), 2.4 ml (P2), 3.6 ml (P3), 4.8 ml (P4) or 6 ml (P5) commercial EM4 per 100 gram faeces. A faeces sample were then fermented at anaerobic condition for 4 days under room temperature. Fermented faeces were then dried at 55oC for 2 days, grounded, and stored in asealed plastic bag before subjected to proximate analysis. The energy content of faeces was calculated from proximate analysis. Experimental results showed that effective microorganism fermentation significantly (P<0.05) reduced crude fiber and protein of faeces (P<0.01), and significantly increased fat (P<0.05), nitrogen free extract (P<0.01), energy (P<0.01) and ash content (P<0.05) of faeces. Moisture was not significantly affected by fermentation. The weights of dry matter (P<0.05) and organic matter (P<0.01) of faeces were significantly reduced by effective microorganism fermentation. In conclusion, the fermentation by EM4 was effective to increase ash, nitrogen free extract and energy of faeces but it was not effective to increase the protein content of faeces (Majalah Ilmiah Peternakan, 2004, 7 (3): 90-93).
Key words: layer faeces, effective microorganism, crude fiber, energy, protein
