[Postpartum torsion of the right uterus horn in a cow].

Four cases of torsion, 180 degrees to the left of the right uterine horn in cows are reported. Two cases appeared about the time of parturition, two within two and four weeks after parturition. The uterine horn was reducible following laparotomy in three animals. It had to be amputated in one case. The authors suppose the size of the uterus to be a factor in the pathogenesis of the uterine anomaly referred to.
