[The Munich obstetric instruments for cattle. Use during the birth of calves in VEL].

The consequent use of the Munich obstetrics instruments can lower the dystochia rate of cows. Based upon the measured traction energy, it is possible to give an objective prognosis of the further process of parturition. By the aid of the traction energy, measured during one labour, the decision to the C. section at the time can get easier. Beside the better survival changes of the calf, injuries of the cow, happened during the delivery, will be extensively avoidable.
