The hematological parameters in clinically normal lactating and ewes affected with mastitis

Abstract

The aim of the present study was to the determine the ranges and means ± SE of hematological parameters in Naemi clinically healthy lactating and ewes with mastitis . The study was conducted on 50 normal and 50 ovine mastitis ( 19 clinical and 31 subclinical ) infected with staphylococcus aureus, both groups aged 2-5 years in Salah al-ddin governorate / Iraq . The blood samples were collected from jugular vein during the period October 2012 till April 2013 . Results showed that the means ± SEin normal lactating and ovine mastitis were as follows ; Packed cell volume ( PCV ) 28 ± 0.27 % and 21.76 ± 0.46 % , hemoglobin (Hb) 9.4 ± 0.12g /dl and 7.56 ± 0.14 g / dl , red blood cell count ( RBC ) 9.52 ± 0.11 ×10⁶/µL and 7.67±0.19 × 10⁶/µL , mean cell volume ( MCV ) 29.39 ± 0.19 fl and 28.43 ± 0.32 fl , mean cell hemoglobin ( MCH ) 9.83 ± 0.08 pg and 9.88 ± 0.08 pg , mean cell hemoglobin concentration ( MCHC ) 33.51 ± 0.19 g/dl and 34.94 ± 0.33 g/dl , erythrocyte sedimentation rate ( ESR ) 6.28 ± 0.15 mm / 24 hrs and 27.08 ± 2.97 mm / 24 hrs , Platelets 247.22 ± 17.88 × 10³/µL and 185.58 ± 14.55 ×10³/µL , white blood cell count ( WBC ) 8.18 ± 0.22 x10³/µL and 14.38±0.26 ×10³/µL, lymphocytes 4509.6 ± 127.6 and 5033.4 ± 412.7 / µL , neutrophils 2857.2 ± 129.2 and 7714.8 ± 415.5/µL , monocytes 371.3 ± 32.7 and 846.9 ± 38.8/µL , eosinophils 331.2 ± 18.8 and 294.7 ± 24.4/µL and basophils 100.6 ± 7.3 and 463 ± 33 / µL respectively . The PCV, Hb , RBC and platelets were significantly higher ( P < 0.05) in normal lactating compared to that of ovine mastitis . The MCV, MCH and MCHC showed no significant differences between normal and ewes with matitis. While ESR and WBC count were significantly lower in normal lactating. Moreover the results revealed significant differences (P < 0.05) in some hematological values of different subgroups .
