abstract
A retrospective study of incidence of dystocia was conducted on sixty dystocia cases in dairy crossbred cows presented to the Teaching Veterinary Clinical Complex, Veterinary College, Hassan. Out of sixty cases 36.67 and 63.33 percent were maternal and fetal causes of dystocia, respectively. Among the fetal causes, maldisposition of the fetus (38.33 percent) was the commonest cause of dystocia. Incomplete cervical dilatation (18.33 percent) was the major maternal cause of dystocia. Other causes of dystocia with low incidence include fetal emphysema, fetal oversize, fetal dropsy, fetal monster, uterine torsion, narrow pelvis and uterine inertia. A higher incidence of dystocia was recorded in primiparous compared to pleuriparous cow and it also associated with a male fetus compared to female fetus. Most of the cases were relieved pervaginally by mutation technique; uterine torsion was relieved by adopting modified Schaffer’s method. Caesarean section was performed in cases where pervaginal delivery is not possible.
