Key words: Drinking thyme essence, broiler, biochemical and hematological parameters.


broiler-chicks-eating-feed-1601This experiment was performed to investigate serum biochemical profile and hematological characteristics of broiler chicks supplemented with different levels of drinking thyme essence (DTE). Five hundred one-day old male chicks (Ross-308) were assigned based on a completely randomized design (CRD) and divided into 4 treatments with 5 replicates. Treatments were arranged in: Control group (plain water), 0.1 ml/lit (0.1%), 0.15 ml/lit (0.15%), and 0.2 ml/lit (0.2%) of thyme essence added to drinking water. At 21 and 42 days of age blood samples were collected from wing vein. According to the results, comparing to control group all treatments significantly decreased serum total cholesterol (TC) and triglyceride (TG) but glucose was increased significantly (p<0.05). Also response of serum total protein, albumin and globulin to different levels of DTE were significantly higher than control group (p<0.05). Serum calcium, phosphorus, uric acid, hepatic enzymes activity including ALT, AST and ALP were not significantly differing than control. Hemoglobin (HG), hematocrit percentage (HCT %), red blood cell (RBC), white blood cell (WBC), and heterophile (HT) counts were significantly (p<0.05) increased by treatments at both 21 and 42 days. In contrast lymphocyte (LY) count was decreased significantly (p<0.05) at both period in experimental groups than control. As a final result, use of 0.1 ml/lit of DTE initially, and afterward the levels of 0.15 or 0.2 ml/lit of DTE in broiler nutrition can improve the blood biochemical and hematological parameters as well as serum proteins without any detrimental effect on liver and health of the birds.
