This study was conducted to investigate the feeding effects of extruded swine manure-food waste(ESF) mixture on growth performance, body composition and feeding behaviour in broiler chicks. The ESF mixture was composed of 40% swine manure, 40% food waste and 20% corn. Crude protein content in diets was 21% for starter and 18% for finisher, but energy content was same(3,100 ㎉/㎏). Feeding trial was done for 6 weeks with 5 treatment groups; control, 10% ESF, 20% ESF, 30% ESF and 40% ESF. There was no significant difference(P$gt;0.05) in body weight gain among treatments, but feed conversion ratio was poor(P$lt;0.05) when the ESF was added 30% or 40% in diets as compared to control and ESF 10% group. Abdominal fat pad was significantly higher(P$lt;0.05) in control than in ESF groups. The contents of crude protein and crude fat in carcass were not significantly difference(P$gt;0.05) among treatments. Liver, crop and gizzard weights were significantly(P$lt;0.05) increased as ESF level increased, but the other organ were not influenced by dietary regimens. Feeding behaviour was greater in day times than in the night and was peaked at before and after draw feeds. Cumulative feeding behaviour was increased with fed higher ESF ratios. In summery, it is concluded that the ESF could he added up to 40% in broiler diets in trials of growth performance.
