Abstract

The feeding trial was conducted to evaluate the effect of thyme leaf as an additive on selected hematological and serum biochemical profiles of white leghorn layers at Haramaya university poultry farm for 11weeks. One hundred twenty white leghorn (WLH) layers at the age of 26 weeks with average initial body weight of 1216.1±6.62 gram (mean±SD) were randomly allotted to four dietary treatments. The treatments were T1 (Layers ration ( LR) with 0% Thyme leaf meal (TLM), T2 ( layer’s ration with 1% TLM), T3 (layer’s ration with 2% TLM) and T4 (layer’s ration with 3% TLM). Each treatment group was replicated three times with ten laying hens and two cocks per replicate in completely randomized design (CRD). Samples of feed ingredients, thyme and formulated diets were subjected to chemical analysis before the actual experiment began. The result indicated that red blood cells (RBC), white blood cells (WBC), hemoglobin and hematocrit percentage of birds did not show significant deference among treatment groups. Serum triglycerides, total cholesterol and LDL-cholesterol were significantly (p<0.05) lower in birds fed a diet containing 2% and 3% than birds fed a control diet. Therefore, the study showed that thyme leaf significantly affects serum metabolites but did not blood hematology.
