Abstract
This study was aimed to determination relationship between zinc levels concentration in the blood serum (PCV, Haemoglobin concentration, differential count of WBC, total protein/dl, albumin g/dl and globulin g/dl) of twenty local breed (Karadi) grazing on pasture plants through April to July month of 2012 in Sulaimani province. Ten sheep were naturally infested with number of 16.9±3.6 hard tick (Ixodidae) and suffered from emaciation, alopecia and hyperkeratosis. The blood picture was estimated and their values were also significant lower P<0.05 in total erythrocyte count 7.8±0.8×106 c/mm3, Hemoglobin concentration 7.3±1.1 g/dl, Packed cell volume 28.5%±2.5 in infested naturally sheep when compared with control in 9.5±0.7×106 c/mm3, 9.92±1.1g/dl and 33.6%±3.6 respectively, and no statistically significant difference in mean corpuscular volume 37.4±5.5 fl, mean corpuscular hemoglobin 10±1.2 pg and mean corpuscular hemoglobin concentration 27.2±4.1g/dl in infested sheep when compared with control in 33.4±5.2 fl, 10.3±0.9 pg and 32±6.3g/dl respectively. Indicated normocytic hypochromic anemia, and there was leukocytosis 11.55±2.2 ×10³ c/mm3 and increase in percentage of neutrophils 52.4%±3.9,basophils 0.9%±0.2, monocytes 5.4%±0.4 and decrease in percentage of lymphocyte 37.1%±3.1 and eosinophils 1.3%±0.2. Biochemical analysis showed significant P<0.01 decreased in zinc level 56.31±3.58 µg/dl by an atomic absorption spectrophotometer (AAS), and significant increase in P<0.05 level in total protein 5.48±0.45 g/dl and albumin 2.31±0.61 g/dl values and increase in globulin values 3.17 ± 0.47 g/dl when compared with ten clinically healthy sheep (control group) 6.83±0.28 g/dl, 4.17±0.43 g/dl and 2.65±0.34g/dl respectively. During the result revealed two genus of Ixodidae (Hyalomma spp. and Rhipicephalus spp.) The objective of this study was to measure the zinc levels concentration and blood parameters in healthy and infested sheep and relationship between zinc level in sheep and hard tick infestation
