Abstract

The aim of this study was to monitor the metabolic profile and oxidative status in goats during the peripartum period.Ablood sample was taken from 10 Red Syrian goats on days21,3, +1, +14, and +28 from delivery. Samples were assayed for glutathione peroxidase and superoxide dismutase activities, and reactive oxygen metabolites, insulin, insulin-like growth factor-I, free triiodothyronine (fT3), free thyroxine (fT4), leptin, urea, non-esterified fatty acids, triglycerides, cholesterol, total protein, albumin, globulin, calcium and inorganic phosphorus concentrations. Blood glutathione peroxidase activity decreased during the postpartum period and its values were significantly (P < 0.05) lower on days 14 and 28 postpartum. Albumin levels were significantly (P < 0.05) lower on days 3, 1 and 28 from delivery compared with day 21. Plasma urea levels significantly (P < 0.001) decreased starting from day 3 from delivery. No effect of time from delivery was noted on reactive oxygen metabolites, non-esterified fatty acids, triglycerides, cholesterol, total protein, calcium and inorganic phosphorus, insulin and leptin concentrations and superoxide dismutase activity. Plasma concentrations of fT3 were significantly (P < 0.01) higher on days 14 and 28 compared with days 21, 3 and 1 from delivery. Plasma levels of fT4 were significantly (P< 0.01) lower on days3 and 1 from delivery. Plasma insulin-like growth factor-I values slowly decreased during the postpartum period and its values were significantly (P < 0.05) lower on day 28. This study indicates that goats experienced moderate oxidative stress during the peripartum period.
