| Abstract | ||
| This study was conducted in the farm of the Animal production Department/ College of Agriculture /University of Baghdad, during the period from 19/9/2014 to 31/10/2014. The aim of this study was to study the effect of adding different levels (0.15, 30 part/ million) and sources of copper (copper sulfate and copper acetate) to the diets of broilers on productive performance and some carcass traits .Also to determine the best source and concentration of copper, and the interaction between them. The experiment was conducted by using 540 unsexy broilers of the organ Ross at the age of one day. Birds were randomly distributed at the age of 1 day on six interactions, (90 Bird/ interaction). Bird were feed on starter for a period of 1- 21 days on diet contain 23% crude protein and 3027 Kcal metabolic energy/kg, and Finisher of diet for a period of 22- 42 days contain 20% crude protein and 3195 Kcal metabolic energy/kg. Two copper sources were used, namely inorganic copper (copper sulfate) and organic copper (copper acetate) with three concentrations for each source 0, 15.30 mg/ kg, according to the following interactions: to form 6 interactions between the copper source and its concentration. The results of the experiment showed as in following No Significant differences between organic sources of copper (copper acetate) and inorganic (copper sulfate) because the difference in the copper source had no significant effect on the productive properties. And that the addition of organic and inorganic copper sources to the diets of broilers in concentration 15 and 30 mg / kg resulted in significant improvement in each of the live body weight, gain body weight and Feed conversion, while no significant effect on feed intake. significant improvement in the productive value, Economic index of the broiler chickens at 42 days carcass relative weight, dressing percentage and the weight of the cleaned carcass, while no significant effect on feed intake. The interaction between (copper acetate, copper sulfate) and the concentrations of 15 and 30 mg/kg exceeded the interaction between (copper acetate, copper sulfate) and the concentrations of 0 mg/kg, and the interaction between copper acetate and concentration of 30 mg/ kg achieved the best results. It can be concluded that the use of 30 mg/ kg of organic and inorganic copper improves the productive performance of broiler chicks | ||
