This study was carried out to investigate changes of physico-chemical properties and microbial activity during the early stage of composting with pig and chicken manure. The results were as follows; 1. The temperature was rapidly increased from the 3rd to the 7th day, and especially the pig manure compost preparing with enzyme was maintained $56^{\circ}C{\sim}69^{\circ}C$. 2. The pH range was shown $7.7{\sim}9.3$, and the pH level increased from the 3rd day to 25th day. Also after the 25th day the pH level decreased gradually. 3. The C/N ratio in the pig manure compost decreased 16.8 at the 30th day, while the compost containing enzymes decreased 19.2 at the 30th day. Chicken manure compost showed similar results at the 28 of C/N ratio at the 30th day with enzyme treatment. 4. The total ammount of sugar in pig manure compost was $6,000{\sim}7,000mg/kg$, while the chicken manure compost was $2,000{\sim}4,000mg/kg$. However, there was no significant difference in view point of enzyme treatment. 5. Cellulase, phosphatase and xylanase activity were continually increased, however amylase and urease activity were not changed during composting.
