Chicken manure contains high nutrients for crop. However, farmers are preferred to use the non-composted manure which makes a serious sanitary problem. One of the most important reason for farmers use non-composted chicken manure is the nitrogen loss reduced fertilizer value of chicken manure.The aims of this study will focus on reducing of length of composting period without reducing of sanitary concerned but can keep most of the nitrogen in the compost. The efficiency of fertilizer value of the short composting manure will be evaluated by pot experiment. The shorten of the composting period will reduce the loss of nitrogen during composting, it also decrease the energy consuming.雞糞是含高量植物養分的農業廢棄物，農民相當喜好使用。然而農民偏好使用未經發酵雞糞造成許多田間衛生問題。農民偏好未經發酵雞糞的一重要因素是雞糞經堆肥化後氮濃度損失多。因此，如何降低雞糞堆肥化時間以降低氮損失，又可兼顧施用後田間衛生的一合理處理方式是相當重要
