This study aimed to provide a complete picture of selected hematological and serum biochemical parameters in Ewes from late pregnancy to early postpartum period. This study was carried out on 120 clinically healthy Native sheep in Elgabal -Alakhdar province in Libya. Animals were divided into three groups, group1 included 20 non-pregnant ewes, group2- included 50 pregnant ewes and group3 included 50 lactating ewes. Blood samples were collected three weeks before the expected parturition from group 2and during the 1st month post-partum from group3.whole blood samples were collected for hematological picture, while serum samples were collected for biochemical analysis which included, serum calcium, magnesium and phosphorus and serum glucose, AST, ALT, and cortisol. Significant changes between pre- and post-partum period (pregnant- lactating) were observed in values of hemogram and biochemical parameters including RBCs, MCV, WBCS count, and differential leucocytes show significant change in lymphocyte count, glucose, calcium, phosphorus, magnesium, AST, ALT, and cortisol. Non-significant changes were observed in Hb, HCT, Neutrophil, monocyte, eosinophil, platelet and basophil. These results concluded that transition period has an impact on some hematobiochemical parameters and ewes should be supplemented with minerals including calcium, phosphorous and magnesium. Investigations of major and minor elements may be considered as real indicators for health in transition period in ewes and helps to prevent many diseases at this stage.
