Swine manure has been recognized as an organic source of composting material, and much research has been conductedfor its efficient utilization and treatment. This study was carried out to analyze the changes in fertilizer composition, heavymetals, and fiber content during composting by mixing pig manure with sawdust. The test was set as a simplesedimentation type composting and a ventilation sedimentation type composting. In EXP1 and EXP2, 100 L and 150 Lof air were blown for each cubic meter of composting material. The composting fermentation period was set at four weeks. The fermentation temperature during the composting process increased from 67oC to 75oC between 1 and 2 days. It wasjudged that this was due to the rapid increase in the abundance of thermophilic bacteria. The contents of the fertilizerduring the composting period were found to be largely changed in EXP1 and EXP2 but not in the REF. Cadmium, mercury,and lead were not detected in throughout the test. The coefficient of variation in copper content in the REF, EXP1, andEXP2 was 0.033, 0.058, and 0.071, and the coefficient of variation in zinc content was 0.025, 0.041, and 0.079. Copperand zinc contents did not change significantly during the composting period. After fermentation, the heavy metal contentof the compost was less than the value determined by the composting organic fertilizer standard. The variation patternsin NDF, ADF, and cellulose contents were similar to one another during the composting period. The change in fiber contentwas larger in EXP1 and EXP2 than in the REF.
