This study was conducted to investigate the feeding effects of extruded poultry manure(EPM) mixture on body weight gain, feed conversion ratio, body composition, panel test and profitability in broiler chicks. The tested EPM mixture was composed of 50% poultry manure, 30% ground corn and 20% tapioca. Protein content in diets was 21% for starter and 18% for finishing, but same energy content was maintained, 3,100 ㎉ for both. Feeding trial was done for six weeks with five treatment groups; control, 10% EPM, 20% EPM, 30% EPM and 40% EPM groups. Compared with control, body weight gain and feed conversion ratio were not significantly different in 10% EPM group (P$lt;0.05), but those were significantly decreased in other groups (EPM 20 to 40%). Carcass percentage was lower in all EPM groups, showing the higher EPM content, the lower carcass (P$lt;0.05). Contents of crude protein and fat in carcass were significantly higher in EPM groups than in control. Also, the fat content in carcass was proportional to the EPM content in diet. Any significant difference was not found in panel test among treatments. Regarding to feeding costs, the higher EPM content in diet was resulted in the lower cost. However, overall profitability was lower in EPM groups than in the control.
