Dystocia is defined as the situation in which spontaneous parturition cannot occur at a given time without any intervention. It can be related to steroid hormone levels and can affect oxidative stress. The purpose of this study was to evaluate the concentrations of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total glutathione (GSH), progesterone (P4), and estradiol (E2) in goats which were parturated normally and with cesarean section. In the study, goats were divided into two groups as normal delivery (n=10) and cesarean delivery groups (n=10). Blood samples of both groups were taken from the jugular vein within the first half-hour after parturition. There was no statistically (P>0.05) difference between the groups in MDA, GSH-Px, total GSH levels. Differences in both SOD (P<0.01) and levels of P4 and E2 were significantly higher in the cesarean group (P<0.05). In conclusion, differences were observed in SOD, P4, and E2 concentrations in goats delivered by cesarean section. It was concluded that the differences in P4 and E2 concentrations might play a role in the etiopathogenesis of dystocia, and the production of SOD, an endogenous antioxidant substance, has increased to combat the increased stress due to dystocia.
