Abstract

An experiment was conducted to determine the effect of dietary supplementation of two Cu sources:  inorganic (copper sulfate) and organic (copper yeast) with different levels of metabolizable energy on productive performance of broiler chickens. Three dietary metabolizable energy levels were used in starter period from 1 to 28 days old (2900, 2800 and 3000 kcal/kg); the corresponding values in finisher period (29 to 42 days old) were 3000, 2900 and 3100 kcal/kg, respectively. One-day-old Cobb broiler chicks were randomly assigned into nine experimental groups, each with three 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. During the whole experimental period, dietary supplementation with organic and inorganic copper caused a significant increase in LBW of birds compared with their controls. Birds fed the high ME diets plus Cu yeast consumed significantly less feed compared with the control group, but chicks fed the low ME diets plus copper consumed approximately similar amounts of feed compared with the control. Birds fed the high ME diets plus organic or inorganic copper displayed significantly better FCR than the control. Dietary Cu supplementation had no significant effect on carcass yield of broilers, expect those fed the high ME diet plus 100 ppm Cu yeast which exhibited significantly higher carcass yield compared with their control group. Birds fed the low ME diets plus 50 ppm Cu yeast or 100 ppm CuSO4 and those fed the high ME diets plus 100 ppm Cu yeast and those given diets plus 50 or 100 ppm CuSO4 displayed significantly higher total edible parts compared with the control group. Broiler fed diets containing the high ME diets supplemented with 50 or 100 mg/kg organic copper had higher means of net revenue and economic efficiency compared with the control birds. It can be concluded that birds fed the high ME diets plus 100 ppm organic copper can improve productive performance of broilers.
