Abstract: The peri-parturient period in sheep, particularly in indigenous breeds like Muzaffarnagari sheep, is marked by substantial physiological changes crucial for parturition and lactation. However, limited research has focused on evaluating blood biochemical and haematological profiles during this critical period. This study aimed to address this gap by examining these profiles in Muzaffarnagari sheep throughout the peri-parturient period. The peri-parturient haemato-biochemical profiling of 10 Muzaffarnagari ewes was done at Livestock Farm Complex, A.N.D.U.A.T., Kumarganj. Results revealed notable fluctuations in blood profiles during the peri-parturient period. The overall average blood haemoglobin level remained relatively stable a week before parturition (10.96±0.27 g/dl), at the time of parturition (10.96±0.30 g/dl), and a week after parturition (10.82±0.32 g/dl). Similarly, the total blood RBC count increased at parturition (9.81±0.34 106/µl) and decreased postpartum (9.24±0.28 106/µl). Total WBC count exhibited a similar trend, peaking at parturition (8.41±0.19 103/µl). Lymphocyte count decreased at parturition (65.9±1.57%) and rose postpartum (69.4±1.83%), while neutrophil count increased at parturition (24.2±0.94%) and decreased postpartum (23.5±0.54%). Serum calcium, inorganic phosphorus, total protein, and cholesterol levels displayed fluctuations across the peri-parturient period. These findings provide valuable insights into the dynamic changes occurring in blood biochemical and haematological profiles in Muzaffarnagari sheep during the peri-parturient period, essential for effective management and intervention strategies to ensure optimal health and productivity of both ewes and lambs.
