Swine diseases

Preface

The experience of the writer in teaching, and in the manufacture and distribution of anti-hog cholera serum, no less than in practice, has forcibly impressed upon him the need of the veterinary profession for more general knowledge of the diseases of swine.

They are not few w^ho maintain that veterinary practice in the future will be concerned largely with the food-producing animals. The automobile has already supplanted most of the fancy driving horses; the auto-truck does much that would otherwise be accomplished by horses; and predictions are rife that the gasolene tractor will soon be made practicable for work on small farms. All things considered it seems probable that the equine population of the country is destined to increase but slowly if at all. The keeping of pet animals, including dogs and cats, is being looked upon more and more as an insanitary practice, while the farm dog and the roaming cur are becoming more and more the object of antagonistic legislation. Contrasted with the foregoing, the increasing price of meat food products makes it seem desirable that veterinarians in general better equip themselves for the treatment of the ailments of food producing animals and thus quahfy themselves to render greater service to the public in a line of practice that is not likely to be affected by progress and invention.

It is the aim of this work to supply this information in a compact, readily assimilated form for both students and practitioners. Acknowledgement must be made to Dr. D. M. Campbell, editor of the American Journal of Veterinary Medicine for the illustrations used herein, and he wishes me to, in turn, acknowledge his indebtedness to Dr. L. Enos Day, in charge of the Branch Pathological Laboratory of the Bureau of Animal Industry of Chicago, and his assistant Dr. G. Tinsley Creech, for permission to photograph a number of specimens in the very excellent museimi maintained in connection with their laboratory. And also indebtedness to the American Serum Company of Kansas City for photographs of their plant used in illustrating the manufacture of anti-hog cholera serum.
