THE PREVENTIVE EFFECT OF IRON, ZINC AND COPPER ON CHICKEN ANEMIA INDUCED BY CADMIUM / 营养学报

ABSTRACT

The causes of Cd-induced anemia and the preventive effect of Fe, Zn or Cu was studied. Day-old male chicken were randomly divided on body weight to 6 groupsA, Basal diet; B, Basal diet + Cd; C, Basal diet + Cd + Fe; D, Basal diet + Cd + Zn, E, Basal diet + Cd + Cu, F, Basal Diet + Cd + Fe + Zn + Cu. After 3 weeks feeding, the parameters to evaluate anemia of the chicken were observed.The results indicated 1. Dietary Cd produced normocytic hypochro-mic anemia in chicken. Its causes were related to the abnormal size and decreased resistance of RBC and the deficiency of Fe and Cu in the chicken. 2. Dietary supplement of Fe and Cu was able to prevent Cd-induced anemia, but Zn had no effect. 3. Dietary Cd produced growth retardation in chicken and it could be prevented by supplementing Fe, Zn or Cu.
