This study investigated the effect of dietary supplementation of chromium from chromium picolinate source on the blood biochemical parameters of broilers. A three hundred sixty- one day old commercial male broiler were randomly allocated to one of 24 floor pens in a completely randomized design with six treatments and four replicate groups and fifteen chicks per each pen. Dietary treatments consisted of zero (control), 400, 800, 1200, 1600 and 2000 μg kg-1 Cr of basal diets. At 42 days of age, two birds from each pen were selected and blood samples were collected from wing vein. Concentrations of high density lipoprotein (HDL), low density lipoprotein (LDL), glucose, cholesterol, triglyceride, total protein and insulin were measured. There were not significant effects of supplementary Cr on HDL and glucose concentrations. But favourably cholesterol (P = 0.0002), triglyceride (P = 0.0004), total protein (P = 0.0003), insulin (P = 0.0004) and LDL (P = 0.058) significantly affected by Cr supplementation. Birds receiving Cr supplementation had lower LDL, cholesterol, triglyceride and higher total protein and insulin concentrations. It can be concluded that under conditions of this experiment Cr addition to broiler diets have an effect on lipid metabolism in broilers.
