Uterine Torsion or Twisted Calfbed.
Uterine torsion is where the womb/uterus/calfbed twists near the cervix , thus preventing a normal birth.
This may not ne easy to recognise as a normal calving pattern does not follow.
Veterinary intevention is required to untwist the calfbed or perform a caesarian operation.
It can occur in all breeds of cattle, both beef and dairy cows.
Predisposing factors are a large calf and exessive cow activity (e.g.running).
The literature states that uterine torsion affecta 0.5 to 1% of calvings, however a swiss vet practice should the prevalence to be 3.6%.
This represented half of all their interventions at calving!
