A 112-day study was conducted to determine the effect of dietary organic (Copper proteinate) and inorganic (Copper sulphate) Cu source on growth performance, plasma lipids and copper residue in organs and tissues of cockerel chickens. 240 day-old commercial Black-Harco cockerel chicks were randomly distributed to 6 dietary treatments of 40 birds each. Each treatment group was randomly allocated to 4 replicates of 10 birds each. The diets were formulated to contain a basal diet (containing 30.62 and 29.71 mg/kg Cu for starter and finisher phases respectively) supplemented with organic Cu (Cu proteinate; Cu-P) or inorganic Cu (Cu sulphate; CuSO 4 ) fed at 3 dietary levels (50, 100 and 150 mg/kg). The birds were fed chicks mash and grower mash at 1-56 days and 57-112 days respectively in a deep litter pen at floor space of 0.06 m 2 /bird. Cu-P supplementation resulted in significantly higher (P |
