poultry is amazingly large. Such losses can be greatly reduced by the 

 farmer having a knowledge of veterinary medicine. The losses from 

 contagious diseases such as hog cholrea, bovine tuberculosis and other 

 diseases can be greatly reduced by proper herd management. A know- 

 ledge of such diseases not only results in financial benefit to the farmer 

 but is of equal benefit to the people of the state and nation. 



In addition to the contents of this book being composed of the 

 knowledge which I have gained from prcatical experience and veterinary 

 training. I am indebted to the results of modern research investigation 

 as conducted by experiment stations and the U. S. Department of Agri- 

 culture for public benefit. 



I am especially indebted to the United States Department of Agri- 

 culture for duplicate electrotypes used to make many of the cuts.
