This study was conducted to determine the effects of different levels (0, 200, 250 and 300 mgCu/kg) of dietary cupper supplementation on some minerals (Cu, Zn, Fe, Mg, Ca and P) found in liver, breast and thigh tissues of laying hens. For this aim, 38-week old total 96 Lohman laying hens as 6 replicate cages each containing 4 hens, were allocated randomly to one of four dietary treatments.
