42 Report OF DEPARTMENT OF ANIMAL HUSBANDRY OF THE 
In accomplishing this end we did not hesitate to reject any 
healthy cow or calf when for any reason it did not give promise 
of being a profitable and desirable dairy animal. Belle of Spring 
Brook was sold for beef before the end of the year because of 
sterility. Pet was also sold for beef because she was not a suf- 
ficiently profitable animal to be desirable for breeding purposes. 
For the same reason five of the reacting animals were disposed 
of at the same time. 
DISINFECTION Otte T ii > TAB PhS 
If the herd was to be kept healthy it was necessary that any 
germs of tuberculosis which may have been scattered in the new 
stable by the tuberculous animals be destroyed. Accordingly the 
new stable was first cleaned and swept and the floor allowed to 
dry. This latter precaution was taken in order to insure good 
penetration of the disinfecting solutions. 
When in proper condition the entire interior of the stable, with 
all the utensils in use there, was sprayed with a solution of cor- 
rosive sublimate, one part to one thousand parts of water.” 
The disinfecting solution was applied in a fine spray with the 
hope of hitting every part of the surface, but the application was 
continued until the surface was soaked so that there might be 
enough material at hand to penetrate to considerable depth in 
porous places. 
When the application of corrosive sublimate was dry the walls 
and stanchions were treated to a coat of oil or paint, depending 
upon the way in which they were originally finished. 
In order to reduce the danger of reinfection and consequent 
aggravation of the disease, as well as to decrease the danger of 
the infected material being carried into the new stable, the old 
stable was also disinfected. 
After a thorough sweeping down and cleaning out, this stable 
was also carefully sprayed with corrosive sublimate. In this stable 
the disinfection was followed by a coat of whitewash. We at- 
tempted to apply this with a hand spray pump, thinking that in 
* This strength is most conveniently obtained by the use of compressed 
tablets which may be obtained at any drug store; or 2% ounces of the 
powdered corrosive sublimate to fifteen gallons of water will give a solution 
of the desired strength.
