Abstract An experiment was conducted to investigate the effect of dietary organic and inorganic copper sources on broiler s performance immune responses and blood parameters In this experiment 420 Ross 308 broiler chicks male were randomly assigned into the 7 treatments with 4 replicates 15 birds per each replicate based on completely randomized design Copper at the rates of 8 16 and 32 mg kg and in the forms of organic copper methionine Cu Met chelate and inorganic copper sulfate pentahydrate was added to the control diet The dietary treatments were offered from 7 to 42 day of age Source of copper had no effect on feed consumption weight gain feed conversion ratios and accumulation of Cu in the liver however inorganic source of Cu at the level of 32 mg kg reduced Fe and Zn content of the liver compared with the control P 0 05 The serum high density lipoprotein and total cholesterol contents remained unchanged however serum triacylglycerol content reduced in chicks supplemented with organic at the levels of 16 and 32 mg kg and inorganic at the level of 32 mg kg sources of Cu compared with control P 0 05 Source of Cu had no effect on anti body titers against Newcastle Disease Virus but SRBC titer increased by organic source of Cu both levels of 16 and 32 mg kg significantly Keywords Broiler Copper methionine total Serum cholesterol anti body titers SRBC Newcastle Disease Virus
