INFLUENCE OF DIFFERENT LEVELS OF ORGANIC CHROMIUM TO THE DIET ON SERUM PROTEINS OF BLOOD BROILER CHICK

Abstract

ABSTRAC: This experiment was carried out at the poultry farm of the College of Agriculture , University of Baghdad during June 12th to the August 8th of 2004, including to study the effect of adding 0,150 and 300 ppb of organic chromium (Cr+3 – Yeast) to the diet on serum proteins of blood broiler chick. A total of 150 day old chicks distributed on the treatments and each treatment divided into two replicates (25 per replicate) . Results indicated that pre – albumin, were not significantly affected by dietary treatment at ( 4 and 8 weeks) of age .serum Albumin and post - albumin in treatment 3 was significantly (p ≤ 0.01) higher as compared with treatments 1 , while treatments 3 were (p≤0.01) higher in γ – Globulin at 4 weeks of age. Albumin / Globulin was significantly (p≤0.01) higher in treatments 3 than the others at 4 weeks of age. At 8 weeks of age Albumin and post – Albumin were significantly (p≤0.01) higher for the treatments 2,3 as compared with the treatments 1. γ – Globulin was significantly (p≤0.01) higher for the treatments 2, 3 as compared with the treatments 1 . In conclusion it appear that adding organic chromium can be used as had the best results considering plasma protein levels in broiler blood.
