Effect of Ventilation Rate on Litter Composting in Poultry Raising

摘要：

Aerobic static litter composting, by using sawdust as main litter materials and adding with pig manure and pig slurry every day, under different ventilation rates of 0, 0.01 m3/min and 0.02m3/min was studied in pilot scale for obtaining the best ventilation rate. The indexes such as temperature, C/N, germination index and microbial population were analyzed to examine effect of different ventilation on litter composting. Re-sults show that: litter composting under ventilation rates of 0, 0.01 m3/min and 0.02m3/min can all realize high-temperature aerobic composting, and coliform bacteria accords with hygienic standard. Ventilation can make high-temperature period prolonged, beneficial for innoxious disposal of litter composting, and ventilation rates of 0.02m3/min proved better.
