Abstract

This study was carried out to determine a suitable mixing rate to utilize the PDF as a bedding materials at the pigpens and investigate the effect of substitute processed dustproof fly-ash(PDF) on the odor. In proportion to the increase of substitute rate of the PDF, the utilizable period was extended, and there was a little change of the moisture in the bedding materials. At all the treatment of PDF, there was the significant effect on the maggots and parasites but it didn\`t hinder in the biodegradation. According to highly mixing rate, PDF decreased in the noxious gas ($NH_3$ and $H_2$S) emission. In conclusion, the mixing rate of 30% or above this substituted level will increase replacement terms, and reduce the sawdust cost and the pollutions of breed pigs.
