The study which lasted 3 months was a factorial arrangement in which nine dietary treatments resulting from supplementation of a commercial layers diet with 0, 200 or 400 mg/kg Copper and 0, 100 or 200 mg/kg Iron were fed to 135 fifty two-week old laying hens of the Golden Hubbard Connect Strain. After 12 weeks on the diets, three birds, randomly selected from each treatment, were slaughtered and their blood, liver, spleen and heart analysed for effect of supplementary copper and iron on haemoglobin content, packed cell volume and weights of the liver, spleen and heart and their copper and iron concentrations. No significant effects of supplementary copper or Iron or their interaction were observed on haemoglobin, packed cell volume or weights of the liver, spleen and heart. However, dietary iron supplementation produced significant (P<0.05) effects on iron storage in the liver and spleen but not on copper storage. On the other hand, copper addition significantly (P<0.05) increased liver storage of copper and spleen storage of iron. Supplementary copper and iron Interaction effects which were not significant for all other measurements, were observed to be significant (P<0.05) for liver copper and Iron concentrations and spleen copper concentration and highly significant (P<0.01) for spleen iron concentration.
