Effect of Zinc Supplementation from Inorganic and Organic Sources on Blood Biochemical, Serum Enzyme, Minerals, Vitamin and Hormones in Kids

An experiment was conducted to elucidate the effect of zinc supplementation from inorganic (zinc sulphate) and organic (zinc methionine) sources on blood biochemical, serum enzyme, minerals, vitamins and hormones in 15 kids divided randomly into three groups (n=5) based on body weights. Group I and II were supplemented with 40 ppm of zinc from zinc sulphate and zinc methionine, respectively, whereas 20 ppm zinc (zinc methionine) was given in group III for 135 days. Blood samples were collected at 0 d followed by 45 days interval for estimation of hematological, blood biochemical, and serum enzymes, minerals, vitamins and hormones. Results revealed that hematological and biochemical parameters did not differ due to supplementation of different sources of Zn except haemoglobin and glucose. Blood hemoglobin (g/dl) was higher (P<0.05) in Gp II than I and III. Serum glucose (mg/dl), was higher (P<0.01) in group I and III than II. Activity of enzymes and minerals were similar in three groups, except zinc and enzyme SOD showing higher (P<0.05) activity in Gp II than I and III. Concentration of serum hormones and vitamins were unaffected by zinc supplementation. It may be concluded that 40 ppm of organic zinc in diet of kids was better as compared to inorganic zinc as it enhanced hemoglobin, SOD activity, serum zinc concentration and decreased serum glucose. Also 20 ppm of organic zinc was as effective as 40 ppm inorganic zinc as hemoglobin, glucose, SOD activity and serum zinc concentration were similar in these groups.
