BACKGROUND Dystocia is one of the most frequent causes of cesarean delivery in nulliparous women. Despite this, its causes are largely unknown. Vitamin D receptor (VDR) has been found in the myometrium. Thus, it is possible that vitamin D affects the contractility of the myometrium and may be involved in the pathogenesis of dystocia. Seasonal variation of dystocia in areas with distinct seasona...

Effect of dystocia, breeding group, cow age and calf sex on periand early postnatal (within 24 hr. after birth) mortality was studied. Data obtained from 1967 to 1972 included 5,064 parturitions from 18 breeding groups. Approximately 35% of the parturitions were from 2,year-old cows, 24% from 3-year-olds and 41% from cows 4 years and older. Type of parturition was divided into four classificati...

Dystocia in buffalo due to fetal causes is not common. However there are reports suggesting dystocia due to dropsical condition of fetus. Present case reports one of the fetal dropsical conditions in buffalo. In this case we report a successful management of dystocia due to fetal ascites in Murrah buffalo by incising the fetal abdomen to take out the fluid from peritoneum. Keywords— Fetal Ascit...

Calving difficulty (dystocia) contributes heavily to losses in production in beef cow/calf herds. The obvious losses are due to calves or cows that die at or soon after calving. Less noticeable losses are due to delayed rebreeding, more open females, an extended calving season and increased labor costs. While occasional dystocia is almost unavoidable, through proper management, cattlemen can mi...
