Abstract

The aim of the present study was to determine the range and mean of hematological parameters in clinically normal Awassi sheep. The study was conducted on 200 sheep 80 males; 40 ram lambs and 40 rams and 120 females; 40 ewe lambs, 40 pregnant and 40 lactating ewes, aged 7 months-4 years in Baghdad governorate / Iraq. Results showed that the range and mean + SE as following; Packed Cell Volume (PCV) 28-45and 33.2+0.27%, Hemoglobin (Hb) 8.6-15.1 and 10.8+0.09g/dl, Red Blood Cell count (RBC) 8.88-14.2and 10.54+0.083×106/ μL, Mean Cell Volume (MCV) 27.54-37.1 and 31.6+0.18 fl, Mean Cell Hemoglobin (MCH) 8.51-12.5 and 10.31+0.07 pg , Mean Cell Hemoglobin Concentration (MCHC) 30.44-36.41 and 32.5+0.10 g/dl , platelets 122-860 and 277.8+ 8.92×103/μL, Erythrocyte Sedimentation Rate (ESR) 2-17 and 8.82+0.27 mm/24 hrs, White Blood cell Count (WBC) 3900-13000 and 10032.7+184/μL, differential leukocytes counts; Lymphocytes (L) 1579-9271 and 5410+122/μL, Neutrophils (N) 1008-8288 and 4167.5+107/μL, monocytes 19-756 and 181.3+10.3/μL, eosinophils 0-1125 and 229.6+16.4/μL and basophils 0-188 and 31.3+3.17/μL and L/N ratio 0.42-3.3 and 1.44+0.04. However the means of following parameters; PCV, Hb, RBC and neutrophils count were significantly different between males and females (P< 0.05). Moreover the results revealed significant difference (P< 0.05) in some hematological values of different subgroups. In conclusion, this study recorded and established the normal reference range and Mean+SE of hematological parameters in clinically healthy Iraqi Awassi sheep.
