Copper between 125 and 250 mg/kg feedingstuff is also effective in
promoting growth of broiler chicken (Pesti and Bakalli,1996; Ewing
et al.,1998; Skrivan et al.,2000).In a study by Pesti and Bakalli(1996),copper (125-250mg/kg feedingstuff) has been shown to
enhance the laying performance of hens and reduce egg cholesterol.
There is obviously no comparative effect of copper on turkeys.
