Studies were conducted to determine the effect of calcium on cadmium level in hens fed diet containing 20 mg cadmium as cadmium chloride and calcium as dicalcium phosphate at two doses 4,95% i 6,6% Ca /kg of feed. One-year old Hy-Line Brown hens were assigned to four groups, each of 12 birds. After 8-week exposure to cadmium hens were killed and sample of kidneys, liver, pectoral and femoral muscles, femoral bone were collected for cadmium and calcium analysis. Cadmium and calcium levels were determined after mineralization by the ICP method using atomic absorption spectroscopy (ICP). In all tissues cadmium content increased. The results showed variability in cadmium levels according to the applied calcium dosage. The highest Cd levels were found in kidneys and liver and the lowest at the muscles. The highest reductions of cadmium were observed in kidneys and the lowest in pectoral muscle: 72,81 and 23,81% respectively.
