    The present study was undertaken in dystocia affected ewes, which were presented to the Obstetrical unit, Department of Veterinary Gynaecology and Obstetrics. Detailed obstetrical examinations were performed in referral dystocia cases of ewes (n=84) and the incidences of maternal and fetal dystocia were recorded and analysed. Further, biochemical and oxidative parameters were recorded and compared between dystocia affected (Group 1, n=6) and normally lambed (Group 2, n=6) ewes at presentation (0 hrs) and after treatment (24 hrs). The incidences of maternal and fetal dystocia in the present study were 64.29% and 35.71%, respectively among the cases presented between January 2020 to December 2021. Uterine torsion was the most common maternal cause of dystocia, accounting for an incidence of 70.38% among all the maternal dystocia cases with an overall incidence of 45.24% among all the dystocia cases. Higher numbers of pluriparous ewes (63.15%) presented to the referral center at 24-36 hrs after existence suffered from right sided uterine torsion (84.22%) and delivered higher number of male fetuses (73.68%) in anterior longitudinal presentation (84.21%) and dorso-sacral to dorso-ilial position. Fetal dystocia (35.72%) also occurred more frequently in pluriparous ewes (66.67%) and higher percentage of fetuses were in anterior longitudinal presentation (86.66%) with limb flexions and most of them were dead (80.00%). Biochemical parameters recorded in the present study revealed that the activity of ALT (IU/L) was significantly (P≤0.01) higher, whereas AST (IU/L) was non-significantly higher in dystocia affected ewes when compared to the eutocia ewes at the time of presentation (0 hrs). Significant (P≤0.05) decrease in the total protein, albumin and globulin concentration in dystocia affected ewes were observed when compared with the eutocia ewes at the time of presentation (0 hrs). While, a non-significant difference (P>0.05) was observed in the levels of mean albumin to globulin ratio in dystocia affected and normally lambed ewes. Oxidative stress parameters recorded in the present study revealed that MDA activity was increased in dystocia affected ewes, whereas SOD and GPx activity were decreased as compared to eutocic ewes. It was concluded that evaluation of ALT, AST, total protein with oxidative parameters (MDA, SOD, GSH-Px) could be used as indicators for the severity of the condition and to predict the prognosis of dystocia. Assessment of oxidative and antioxidant parameters were necessary to initiate emergency care and to attempt early treatment of dystocia to improve the prognosis and for prompt recovery.
