Association among antioxidant status, hormonal profile, and biochemical parameters during the periparturient period of dairy cattle in Upper Egypt
Journal Title: Journal of Multidisciplinary Sciences - Year 2019, Vol 1, Issue 2
Abstract
The present study attempted to evaluate the physiological modification in the antioxidant status, hormonal and biochemical profile of dairy cattle in Upper Egypt during the periparturient period. Blood samples were obtained from the jugular vein of 25 healthy dairy cattle from a private dairy farm in Assiut province, Egypt. Blood samples were taken with 7 days’ intervals: two weeks before and two weeks after parturition (during the periparturient period). The collected serum samples were analyzed for determination of biochemical and hormonal parameters including: progesterone (P4), estradiol (E2), cortisol, triiodothyronine (T3), thyroxine (T4), total antioxidant capacity (TAC), malondialdehyde (MDA), blood glucose (BG), triacylglycerol (TG), Total cholesterol (TC), calcium (Ca2+) and phosphorus (P3+). Our results indicated that serum P4 levels were significantly decreased post-partum than during the pre-partum period. E2 level reached the maximum on the day of calving as compared with the pre-partum period. The serum cortisol level was highly elevated at calving day. T3 concentration was significantly higher on the 7th day postpartum, while a higher level of T4 was recorded at 15th-day post-calving. TAC and MDA showed significant changes during our study. The BG increased significantly reaching the maximum level on the calving day, then it was sharply decreased on the 7th-day post-calving. TG and TC levels showed a significant reduction in two weeks post parturition. A significant reduction of both Ca2+ and P3+ was noted at the calving and post-partum period. The periparturient period was associated with significant changes in hormonal, oxidative stress and biochemical blood profiles comparing with the pre-partum period.
