Different methods are used in the processing of poultry waste. The selection of the system climate, animal type, capacity, economic conditions and the purposes of re-use is effective. Aerobic and anaerobic processing as a waste managing operations of poultry feces, composting, such as burning, as well as the methods used in recent years, different drying techniques. In this study, the microbiological and chemical values of chicken feces are emphasized with new drying system. Prior to drying, the fecal coliform (FK) and total coliform (TK) counts of the chicken feces were determined as 1,3x106 and 2,8x106 respectively, after dried the same parameters were found as <10 and 30 respectively. Prior to drying the organic nitrogen (OA), total nitrogen (TA), total phosphorus pentoxide (TF, P2O5), potassium oxide soluble in water (SPO, K2O), moisture and volatile matter (NUM) and pH values were 1.6%, 1.8%, 2.7%, 1.7%, 65.6%, and 8.5, respectively; after dried, the same parameter values were found as 3.2%, 5.4%, 4.1%, 4.8%, 11.2% and 7.1 respectively. In a second study, after drying focused on the chemical structure of pellets chicken feces and their moisture and volatile matter, total nitrogen, total organic carbon (TOK), calorific value (KD) and pH values were found 24.9%, 1.6%, 37.1%, 14.896 kJ/kg and 7.2 respectively. As long as according to the analyzes of economic, the development of new drying system concluded that available in long-term storage of chicken feces without harming the environment or biogas production, composting and the product obtained after other processing methods which is bringing the desired level of moisture and structure of microorganism.
