One hundred and thirty dairy cattle that had undergone a caesarean operation because of dystocia were assigned either to a treatment group, receiving 25 mg dinoprost (synthetic prostaglandin F2 alpha) or to a control group, receiving 5 ml saline solution, administered intramuscularly after removal of the calf and reposition of the closed uterus into the abdominal cavity. In 52 of 65 (80.0 per cent) prostaglandin-treated animals and in 38 of 65 (58.5 per cent) control animals the complete placenta was expelled within 12 hours. This difference was statistically significant (P < 0.05).
