Hematobiochemical profile in Surti goats during post-partum period

Abstract

Aim: The study was undertaken to find out the changes in hematobiochemical profile in post-partum Surti goats. Materials and Methods: The present study was conducted on 40 Surti goats out of which 20 goats who had undergone recent parturition acted as treatment group and 20 non-pregnant animals comprised control group. Blood samples were collected from the treatment group on 0, 7, 14, 21, 30, and 45 days post kidding and once from the control group. Blood samples were analyzed for hematological parameters such as hemoglobin (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total leukocyte count (TLC), differential leukocyte count, and biochemical metabolites such as total protein (TP), albumin, globulin, total cholesterol (TC), triglycerides (TG), non-esterified fatty acid (NEFA), glucose, and urea. Results: Hb level was the highest on the 45th day and lowest on the day of parturition. Significantly low level of Hb, PCV, and lymphocyte was found on 0 day and significantly high level was found on the 45th day. TEC was also low on the 0 day and high on the 45th day post kidding, but the difference was non-significant. Mid-sized cells and granulocyte percentage decreased significantly from 0 to 45th day post-partum. TP, albumin, and urea were found to be lowest on 0 day and highest on 45th day post-partum. Urea concentration increased parallel to TP indicating an increase in urea production with catabolism of protein. The globulin concentration also increased from 0 to 45th day post-partum, but the difference was non-significant. TC, TG, and NEFA were the highest on 0 day and lowest on the 45th day post-partum. Decrease in TC and TG from 0 to 45th day post-partum indicates that the animals utilized the lipids for the supply of energy for milk production. High level of NEFA acts as an indicator of negative energy status but in the present study, the high glucose level on 0 day indicates that the animals were in positive energy status. The glucose concentration decreased up to 14th day post-partum and then started increasing from 21st day onward. Conclusion: Hematobiochemical parameters are indicative of health status of animals. Significantly low values of Hb, PCV, and TLC during first 2 weeks post-partum are indicative of stress. Catabolism of protein occurred during 2 weeks post-partum, as observed from increase in urea concentration. Decrease TGs and high level of NEFA during the transition period are suggestive of utilization of lipids for the supply of energy. High glucose level on 0 day indicates that the animals were in positive energy status.
