The effects of long-term cadmium exposure in turkeys: Accumulation and zinc prevention

Experiments with turkeys were conducted to determine the effects of long-term ingestion of Cd (2.0 mg Cd/day/turkey) on its accumulation in the tissues and organs. The cadmium was found especially in the muscles, livers and kidneys. The highest average content of cadmium was found in the kidneys (1.09 mg/kg). The contents of Cd in the kidneys and livers were 19 times and 14 times (respectively) higher compared to the muscles. The administration of Zn (72 mg / day / turkey) along with high doses of Cd, significantly (P < 0.001) reduced the concentrations of Cd in the organs of the experimental animals. The average concentrations of cadmium in the kidneys and livers of turkeys from the CdZn group were 43 % and 48 % (respectively) lower than the average concentrations in the same organs in the turkeys from the group which received only Cd.
