Biochemical Effect Of Chromium Element On Lipid Profile Of Broilers

This study was conducted to investigate the effect of water chromium chloride supplementation on lipid profile and some serum parameters of broilers. Eighty newly hatched cobb broiler chicks were equally distributed to four groups of 20 chicks each. The first group fed basal diet and normal water, the second group fed high fat diet and normal water, the third group fed a basal diet and water supplemented with chromium chloride (30 mg chromium chloride / liter water), the fourth group fed high fat diet and water supplemented with chromium chloride. Blood samples were collected for the determination of serum lipoproteins, glucose, total lipids, triglycerides, cholesterol, thyroid hormones and leptin hormone. Chromium decreased VLDL and LDL but increased HDL. A reduction in serum glucose was observed with watery chromium supplementation. Serum total lipids and triglycerides were non significantly decreased but serum cholesterol was significantly decreased with watery chromium supplementation. Serum thyroid hormones were non significantly increased but the serum leptin hormone was significantly increased with watery chromium supplementation.
