Hematological Profile of Achai Cows during Different Stages of Pregnancy in Kohistan Hindukush Mountainous Range

Pregnancy is a common situation and concurrently the most altered physiologic state consisting of variety of physiological and hormonal changes. These changes begin after conception which alters the normal physiological status of blood. The present study was conducted to evaluate changes in hematological biomarkers of Achi cows at different stages of pregnancy. Forty multiparous cows with 4 +/- 1 years of age and live weight of 188.23 +/- 2.6 to 207.13 +/- 2.59 kg of different stages of pregnancy were divided into four groups (Group1=1(st)trimester Group 2= 2(nd)trimester and Group 3= 3(rd) trimester, Group 4= non-pregnant). Blood samples were collected from all the animals and assayed for hematological biomarkers like erythrogram, leukogram and erythrocyte sedimentation rate (ESR) were determined during three stages of pregnancy. The highest RBC count was recorded in group 4, The highest Hb, MCH and MCV was recorded in group 3. The lymphocytes and neutrophils were high in group 2 and group 3 respectively as compare to other groups, the leukocytes was low in group 4 and high in other groups, the eosinphil was high in group 3 where the monocytes was high in group 1 and group 3 as compared to other groups. The ESR was high in group 2 and low in group 4 as compare to other groups.
