Dystocia in the dairy cow is by no means a new topic of discussion. Every general practitioner has at times been confronted with this condition, and is familiar with the problems pertaining thereto. It is not the purpose of this paper to enter into a treatise on this subject, but rather to present a case which we feel merits the attention of our colleagues.
