Hog Cholera Control 
By GEO. H. GLOVER 
INTRODUCTION. 
Hog cholera is the greatest menace to the hog raising industry. 
Were it not for cholera, hog raising in practically all sections of 
Colorado, would be one of the most profitable branches of the live¬ 
stock business. It is conservatively estimated that more than 90 
per cent of the deaths of hogs from disease are caused from hog 
cholera. 
Until recently the idea prevailed that hogs in Colorado, be¬ 
cause of altitude and climatic conditions, were immune to cholera 
and this delusion has no doubt been responsible for much 
spreading of the disease in the state. The loss from hog cholera 
throughout the nation exceeded one hundred million dollars in 
1913, and in Colorado over half a million, mostly in the San ,Luis 
valley, with several outbreaks in the Arkansas valley and the north¬ 
ern portion of the state, east of the mountains. 
We are convinced, after our experience with hog cholera in 
the San Luis valley, that the disease can be controlled, but to ac¬ 
complish this throughout the state there must be active and efficient 
supervision, combined with hearty co-operation on the part of hog 
raisers, importers and dealers. 
This bulletin is prepared primarily to furnish information to 
the farmer as to what will be expected of him in a united effort to 
control hog cholera in the state. 
The principles of farm sanitation and a practical application 
of the same are not generally well understood, neither is the im¬ 
portance of this subject fully appreciated by the farmer. If the 
farmer had made as intelligent use of the principles of sanitation on 
the farm as has been made in the control of diseases in man, the 
* 
extensive dissemination of hog cholera, tuberculosis, contagious 
abortion, glanders and other infections would never have happened. 
CAUSE OF HOG CHOLERA. 
There is only one thing that will cause hog cholera and that 
is the specific germ of the disease. Worms will not cause hog 
cholera, neither will poor feed, impure drinking water, change of 
feed, crowding them together in transportation, or filthy conditions
