For many years the writer has been acutely aware of the many problems associated with the efficient management of a mixed veterinary practice. The veterinarian whose main interest is small animal medicine will find that even though he has the opportunity to conduct both a large and small animal practice he will gradually build up the pet practice and let the farm practice go. The reverse holds true, of course, for the veterinarian whose main interest lies in large animal medicine.
