Infected feedlots should be disin-
fected as follows: Pieces of boards,
rails, cornstalks, cobs and other
rough litter lying around in the infect
ed feedlots should be piled up in the
middle of the lot and burned; lime
should then be spread thickly over the
ground, so that the ground will look
as if covered with a light snow. If
large feedlots are to be covered, a
lime spreader may be used. But a
wheelbarrow and shovel answer the
purpose we'll enough, even for large
feedlots. Keep stock off the ground
for a few days, then scrape up the
manure into windrows with two
horse, homemade board scraper.
Scatter more lime on the windrows,
add small Jumps of the unslacked
to increase the heat, then shovel the
manure and lime into rounded piles,
sprinkle more lime over these piles,
and let stand for few days. The ad-
dition of little water to these piles
is advisable, if the barnyard manure
is dry. This will increase the slack
ing and heating process in the ma
nure heaps, which will effectually de-
stroy the cholera germs. The eggs
and embroys of five or six different
kinds of worms that commonly infest
hogs, and occur in hog dung, will al
so be destroyed by the lime After
treatment in the manner mentioned
the barnyard manure can be scattered
with safety on the fields. The mix
ture of lime and manure will help to
sweeten and fertilize the soil where
field is to be sown to alfalfa or clo-
yer. The clean feedlots should be
covered again with another dressing
of lime. Lumps of unslacked lime
may be scattered over the moistened
hogyards, and spread about by means
of a rake, while Stacking.
The hoghouses, cots and fences
should be whitewashed, inside and
outside, with hot lime wash. AS tC
the value of lime as a disinfectant
when used freely, it may be said that
one of the best swine breeders in Mis-
souri, was able to restock his breeding
quarters within go days after having
had severe losses from cholera. Ht
used nothing but fresh air-slackeC
lime, but he did thorough job Of
disinfecting by using the lime freely
An experiment was made by thu
veterinary department of the Missouri
Experiment Station in the disinfec
tion of cholera-infected pen, in ont
of the local railroad stockyards {;
pen in which number of hogs hat
died from cholera). This pen wa
treated to an application of fresl
air-slacked lime. In few days si'
pigs were turned into the pen, ant
fed there for three weeks. They diC
not receive any medical treatment
nor special care; no symptoms of i'll
ness had developed at the end of tht
period. These same pigs were put il
clean pen for few weeks at th'
State farm for further observations
None showed any signs of cholera
Then, as test of their susceptibility
they were exposed to infected pens a
the serum plant. They promptly
took the disease and nearly all died
This experiment demonstrated thai
quicklime or freshly air-slacked lint
was an efficient agent in disinfectine
the badly contaminated hog lots il
the stockyards.
The cresol compound solution, made
according to the United States Phar
macopoeia, has been found by labora
tory tests at the United States Bu
reau laboratories to be one of the
most efficient chemical disinfectant'
for destroying hog cholera germs, ant
may be applied in the form of a spray
Mix / pint to 8 or a gallons of water
This is useful in disinfecting wagon
boxes, hog crates and the floors ant
walls of hog houses. Lime, however
seems to be preferred by most farm
ers, especially for the use on the
grounds, and its reliability has beer
demonstrated both by laboratory anc
field use. Besides, it has an advan
tage over the cresol and the ordinary
carbolic stock dips in being of value
to the soil instead of harmful. The
ordinary carbolic dips and disinfec
tants are not so efficient in destroying
hog cholera infection as the creso
compound solution, according to test:
made by the United States Bureau o.
AHlHldl lIlNuSbFy.
The disinfection of large fields, pas
lures and woodlands by means o.
chemical disinfectants, such as lime
and cresol compound solution, is o.
course impractieable; yet. such field:
can be made safe for susceptible hogs
If hogs are kept out of infected field
for sufficient time, the germs of tht
disease die. The germs do not seen
to have the power of multiplying out
side the body of the hog, although th'
life of the germs may be conserve;
for a while outside of the body, /
conditions are favorable. It has beer
observed that the hog cholera infec
tion dies out more quickly in opeI
fields, well exposed to the rays o.
the sun, than in moist, shaded places
The cholera germs on exposed grounds
are killed quicker during the summer
months than in winter. Strong sun
light is a good disinfection agent fo
a number of disease germs, anC
among them hog cholera.
It is advisable to put cattle, horses
and sheep on the cholera-infected pas
lures, and let them crop the grass
closely, so as to give the grounds 9
good exposure to the hot rays of the
summer sun. Hogs ave not so apt tc
contract cholera in the large fields as
in the smaller feedlots, since the in
fection would not be so concentrated
