An experimental research on composting swine feces was carried out, by changing technics and bulking agent. The results showed that the improved technology can shorten the ferment time obviously and deodorize manure efficiently. Adding bulking agents including sawdust, dry feces and mushroom dregs in fresh swine feces, regulating initial stock water containing ratio around 65%, and inoculating suitable bacterial preparation were in favor of the maturity of composting. As bulking agent, dry feces and mushroom dregs have similar effects, but dry feces gets easily and has higher translation rate of nitrogen.
