This study was conducted to investigate the effect of increasing dietary levels of inorganic chromium (CrCl3A6H2O) on the performance and some serum parameters of chicks. One hundred 1-day-old Bovans-type chicks were randomly distributed to four groups. The control group received no supplemental chromium. 0.2, 0.3 and 0.4 mg chromium (Cr) kg-1 diet from chromium chloride were added to other three groups. Each experimental group consisted of five replicates each of five birds and the supplementation was continued for 35 days. Blood samples were collected for the determination of serum concentration of proteins, albumin, glucose, total cholesterol, High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL) cholesterol, triglycerides and the activities of spartate aminotransferase (AST) and Alkaline Phosphatase (ALP). Chromium by the doses used had no effect on weight gain. Supplementation with Cr decreased the serum total cholesterol, LDL cholesterol (p<0.05), triglycerides (p<0.05) and glucose (p<0.05) concentrations whereas serum HDL and cholesterol were increased. Serum total protein concentration, AST and ALP activities slightly but not significantly increased in all Cr. treated groups.
