with this disease, the best method of procedure in most cases is to have
the affected animals slaughtered and the stables disinfected. A large
proportion of the animals which are slightly affected yield carcasses which
are perfectly wholesome and fit for human food, but in all such cases there
should be an inspection by an expert at the time of slaughter to determine
which carcasses may be used and which should be destroyed.

The disinfection of stables may be accomplished by thoroughly cleaning
them, scrubbing the floors with hot water, brushing down all loose dust
from the walls, and tearing off all woodwork which is partly decayed. Then
the whole interior of the stable should be covered with a good coat of
limewash containing 1 part of formalin (which is a 40 per cent watery
solution of formaldehyde) to 30 parts of the lime wash, or 4 ounces of
formalin to each gallon of lime wash.

Similar precautions should be observed in removing the manure of the
infected herd from the barnyard and other places accessible to cattle,
since it is known that tuberculous cattle frequently eliminate large
numbers of tubercle bacilli through the feces. The ground under the manure
pile should then be disinfected, either by the above-mentioned formalin
solution or by unslaked lime thickly sprinkled over the soil.

If all the animals which react are destroyed and the stables disinfected in
this manner, the herd should remain free from the disease unless other
affected animals are added to it. The introduction of the disease in this
manner may be avoided by requiring a tuberculin test of all new animals
admitted on the premises.

Unfortunately it is a fact that tuberculous animals which have been tested
several times may become so accustomed to tuberculin that they will no
longer react; consequently it is always advisable to purchase cattle from
some one who is known to be reliable, as otherwise animals of this kind may
be treated with tuberculin for the purpose of hiding the disease.

In the case of very valuable purebred animals and under exceptional
circumstances it may be more advantageous to retain the reacting animals
which are in good condition in order to breed from them and in that manner
avoid the excessive loss which would follow from their immediate slaughter.
This may be done if proper precautions are adopted.

The disposal of reactors depends upon the State laws and live-stock
regulations of the State in which the herd b
