The primary concern of the veterinary profession is the service it can render to mankind. The significance of veterinary medical services is measured by the availability of food which is supplied efficiently, the emotional and psychological improvement of others through the enjoyment of companion animals, and improvement of the public health by control of diseases of man which may result from contact with animals.
