Abstract
This experiment was carried out at private commercial poultry farm under supervision of Animal Production Department,Faculty of Agriculture,Tanta University during the period -#102;-#114;-#111;-#109; March to May2015 The main objective of this study to investigate the effect of br dietary inorganic and organic copper with different energy levels on productive, physiological performance, copper accumulation in the pectoral muscle and economic efficiency of broiler chicken. Filed study:Four hundred and five (405) one-day-old unsexed Cobb broiler chicks, purchased -#102;-#114;-#111;-#109; a commercial hatchery, were used in this experiment.Chicks were individually weighed to the nearest gram and randomly assigned into nine experimental groups, each with three br replicate groups. Diets containing 2900 and 3000 kcal ME were used as controls for the starter and finisher periods, respectively. In the starter diets (2800 and 3000 kcal ME/kg) Cu was supplemented at 50 and 100 mg/kg as copper yeast and at 50 and 100 mg/kg as copper sulfate. In the finisher diets (2900 and 3100 kcal ME/kg) the same sources and levels of Cu were added
