The research was carried out on 2 groups of heavy type turkeys BIG-6 (100 birds each). All the birds were kept under regular environmental conditions, according to the accepted norms of industrial fattening. Turkeys were fed standard complete mixtures and had unlimited access to water. The turkeys of experimental group received the supplement of Cu chelated with lysine in drinking water at the concentration of 10 mg Cu/cubic dm H2O. The research showed that the final body weight of experimental turkeys was higher compared to the control birds. The addition of Cu-bioplex decreased the fresh bone weight by 14.1 percent and the air dry matter of bone by 8 percent. The share of tibia bones in the experimental turkeys body weight was decreased by 20.5 percent compared to the control group. The durability of tibia bones in turkeys given chelate was lower by 6.7 percent than the value describing the control group. The supplement of Cu-bioplex had no significant effect on the content of tibia crude ash but it decreased both Ca and P concentrations and increased the content of Mg whereas the content of Cu was the same in every group
