Effect of copper as feed additive on body weight, feed efficiency and immune response or broilers [electronic resource].

Includes references.

This work was carried out to study the effect of different levels of copper supplementation in the broilers diet on growth performance and immune response. It was conducted with one hundred and twenty. one day-old Cobb broiler chicks that were evenly distributed to four equal groups of 30 chicks for each. They were fed On four experimental rations for SIX weeks experimental period. The first group was fed On a basal diet (control group, G1), and the remaining groups were fed 63(G2), 75 (G3), or 125(G4), mg Cu/kg diet. Body weight and feed efficiency were determined weekly. Also the primary and secondary antibody responses were determined. When the chicks were 4wk of age, a delayed type hypersensitivity test was performed White blood cells were differentiated and antibody response was determined.
