Abstract
Recently, the treatment of dead poultry has become more important issue because, the infected poultry, which was buried under the ground, causes environmental contaminations such as steep water and reek occurrence, etc. Therefore, in this study, we investigated the type of treatment and the composting methods influencing to the characteristics on decomposition and fermentative disinfection of dead poultry with poultry manure and sawdust. The results of the port tests showed that amputated poultry treated by the cut-sterilization were not only more decomposed, with less smell compared to the non-treated poultry carcass. When we treated thermophilic microorganism such as bacillus in this amputated poultry, the temperature of treated poultry increased much fester, the fermentation temperature didn't rise and not maintained constantly for long time due to the small size of the fermentation port. On the other hand, we did fermentation test by the layered disposal method with more poultry. In this experiment, the temperature of fermented poultry rose to $54^{\circ}C$ in a day and maintained around $55^{\circ}C$ during four weeks period. With less odor outside the experiment room. further. Also, we inoculated AI virus, ND virus in the excrement for studying the effect of fermentative disinfection. The result of the test revealed that AI virus was destructed within 60 minutes and ND virus was destructed within 30 minutes at the temperature of $56^{\circ}C$. Therefore, the investigations revealed scope of composting method for steam sterilized infected poultry in the originated area mixed with poultry manure, sawdust by thermophilic microorganism could increase the effectiveness of fermentative disinfection and decrease the environmental contamination.
