Samples of poultry manure were dried by different drying methods using air temperatures from 21.5 deg C to 110 deg C in order to investigate the effect of temperature on the quality of dried poultry manure. The lowest moisture content achieved in laboratory conditions was 16.84%, the lowest moisture content achieved in conditions similar to those in animal housing was 33.65%. These values were gained after 48 hours of drying. The values of moisture content were significantly influenced by the drinking system. Higher moisture content was measured for laying hens using nipple drinkers compared to those equipped with downspout accessories.
