Influence of Zinc and Chromium Supplementation on Blood Biochemical Constituents and Hematological P

Aims: An experiment was conducted to investigate the effect of supplementing zinc-methionine and chromium-picolinate on blood biochemical constituents and hematological profiles of goats.

Place and Duration of Study: The present studies were carried out at Department of Animal Nutrition, College of Veterinary Science and Animal Husbandry, Anjora, Durg during February 2007 to August 2007.

Methods: Twenty-four indigenous non-descript goat kids (3-5 months old, average body weight of 5.1±0.25 Kg) were allocated to four groups Group-I (control) was fed ad libitum basal complete feed which constituted sola (Aeschynomene indica) - hay (60 parts) and concentrate mixture (40 parts). The kids of Group-II, III and IV were fed as in control with a combined supplement of Zn-methionine and Cr-picolinate at the rates of 20 and 0.5 parts per million (ppm), 35 and 1 ppm and 50 and 1.5 ppm, respectively. The experiment lasted for 90 days. Hemoglobin, packed cell volume (PCV) and total erythrocyte count (TEC) were performed as per the method described by Jain [4]. Blood biochemical study was performed by using Spectrophotometer.

Results: There was progressive increase in total protein, albumin, globulin levels and alkaline phosphatase activity in serum in mineral supplemented group as compare to control. In most of the cases erythrocyte count, hemoglobin (Hb) concentration and packed cell volume (PCV) were significantly (P<0.05) higher with the increase of Cr-picolinate and Zn-methionine concentration in basal diet than control. However, blood glucose and total cholesterol, triglyceride, high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol in serum were significantly reduced due to mineral supplementation.

Conclusion: On the basis of the present experiment, it may be concluded that dietary supplementation of Zn-methionine and Cr-picolinate at the rates of 50 and 1.5 ppm, respectively had significantly improved their blood biochemical and hematological profile of desi goats.
