Evaluation of leukogram changes in the pregnant Lori ewes before pregnancy, during pregnancy and lactation periods

The aim of this study was to investigate the changes in some blood parameters in 15 Lori ewes during pregnancy and compare it with one month before pregnancy and lactation. Blood samples were taken from the jagulur vein before normal mating as a control, at the end of every three months of pregnancy and two weeks after delivery during lactation, and the complete blood cell count of each sample was evaluated by a veterinary cell counter. Giemsa staining and differential white blood cell count were performed on blood smears and total plasma protein values ​​were evaluated by refractometry. The number of red blood cells and the percentage of hematocrits during lactation were significantly reduced compared to pregnancy (P˂0.05). Mean cellular volume was reported in all periods in one spectrum. The Decrease in the mean hemoglobin levels of red blood cells, mean hemoglobin concentrations in red blood cells and platelet count in pregnancy were observed compared to before mating. The number of leukocytes and neutrophils increased around parturition and decreased after parturition. During pregnancy, the number of eosinophils increased significantly and decreased after parturition (P˂0.05). The number of monocytes and lymphocytes increased in late pregnancy and decreased during lactation (P˂0.05). The amount of total protein in the plasma decreased significantly from 100-150 days of pregnancy (P˂0.05). Thus, base on the results of the present study monitoring of changes in blood parameters of Lori ewes, dietary adjustment and preventive measures are necessary to prevent blood disorders such as anemia and thrombocytopenia.
