Various solutions may be used for
dlslnfection, the more efficient ones
are the following:
Solution 1. Corrosive sublimate dis
solved in rain water in a proportion
OF l-lOoo (seven ounces of sublimate
to fifty gallons of water, approximate
cost 5O to 55 cents). Put the water
IN a clean barrel, add the sublimate
and leave it t~wenty-four hours before
using, stirring it occasionally in order
to secure perfect solution.
Corrosive sublimate is the cheapest
n the most efficient of all disin-
f%ectants, but has the disadvantage of
pelng very poisonous, or attacking
metals and of having it's germ killing
properties reduced by the presence of
organic matter and when dissolved in
hard water.
Solution 2. Carbolic acid dissolved
in water g to 4 per cent?. This is
an efficient, time honored disinfectant.
A good solution is made as follows:
10 fifty gallons of water add five
pounds of washing soda and ten
pounds OF pure carbolic acid. Stir un-
I'll the solution is clear, when it is
ready for use. approximate cost
$3.50 to $4).
Solution 3. Creoline or similar
preparations, mixed with water, 2 to
4 per cent. To fifty gallons of soft
water add ten pounds of ~creoline. CAD
proximate cost 50 to So.
Solution 4. A mixture of chlori-
mated lime in water (twenty pounds
OF c~hlorlnated lime to fifty gallons Of
Water-approximate cost 81 to s1.50).
This mixture must be prepared i'm
medlately before use and the lime
must be fresh or contained in closed
containers. This is a very effective
dlslnfectant, but when dealing va
CHAMBERS or tuberculosis any of tie
above mentioned substances are to be
preferred. C%hlorinated lime is espe-
clally useful for the disinfection of
dirt floors, pens, yards and drains.
All liquid disinfectants must be ap-
pied by means of the spray pump,
sprlnklers or the brush. They must
be applied thoroughly and abundantly.
IT is advisable to apply the sublimate.
carbolic acid and creoline solutions
while hot. The hotter they are the
greater will be their germ DESTROYING
properties.
In disinfecting stables care must be
taken that all cracks and ~crevices are
reached and all utensils must be in
cluded in the process.
Before beginning disinfection prop
er, stables, pens, stock yards, cans,
etc., should be thoroughly cleaned.
All litter, manure, dirt, dust, ETC.,
SHOULD be carefully removed and de-
stroyed by burning. When this is not
possible, it should be thinly spread
over the ground at places where live
stock cannot come into contact with
it. The exposure to the fresh air and
sunlight will render it harmless in
time. -.
When dealing with the more viru-
lent disease, such as CHAMBERS, hog
cholera and tuberculosis, it is advis-
able to remove feed boxes and old
hangers. They may be destroyed by
fire and replaced by new ones. It is
often difficult to d~isinfect them and
In many cases the expense involved in
replacing them by new ones is a good
investment.
In stables, pens, etc., having a dirt
floor it is advisable to remove from
two n one-half to three inches of
the top, as infectious material is apt
to soak in and when embodied in the
dirt it is difficult to destroy it.
Wagons used for hauling infected
litter, dirt, ETC., should be thoroughly
cleaned and disinfected in the same
manner as the stable proper.
