Locations of the United States Department of Agriculture’s animal disease research work. 
quiring hog producers to cook garbage 
used for feed, the disease was eradicated. 
The USDA’s fundamental and ap- 
plied research on animal diseases has 
been conducted at Washington, D.C., 
Bethesda, Md., the Animal Disease Sta- 
tion at Beltsville, Md., and various field 
stations. 
Research has been apphed by veteri- 
narians and farmers to improve the 
health of animals and to reduce disease 
losses. It has been the basis for 
eradication programs and the foundation 
for further disease investigations. 
With the reorganization of the De- 
partment of Agriculture in 1954, the 
Animal Disease and Parasite Research 
Division was assigned the basic function 
of investigating all animal diseases. The 
Ames laboratory is an extension of this 
assignment. In initiating vital research 
in the modern research center, the Fed- 
eral Government will augment—not re- 
place—the valuable animal-disease work 
of State and private laboratories.
