duently entirely overlooked or, in
other words, given no attention.
Frequently diseased herds are
treated as healthy, or in some herds
a wrong diagnosis is not uncommon.
Pigs suffering from pneumonia, in

prevailing constitutional disease
brought about by improper housing
and feeding, may be vaccinated to-
prevent cholera, with the result
that the animals in the herd contiue
to die until conditions causing
| the trouble have been corrected.
The average results would be much
better if each herd before being
treated were examined carefully,
! and if any disease exist a positive
diagnosis should be made. II is not
practical to vaccinate healthy hogs |
in sick herds unless the disease is
hog-cholera. Under some condi-
tions owners are justified in using
serum before an absolute diagnosis
is made in order to avoid the de-
velopment of possible cholera in
lection, especially if the disease is
prevalent in the locality.
Hog-cholera may exist in differ
ent forms and mislead the owner or
even the experienced veterinarian
in the preliminary stages of the dis
ease; it is not always typical and some
animals may suffer from a very
mild form of the disease and involve
a large number in the herd before
the exact extent of the contagion is
known. On the other hand some
herds are extensively infected with
the mild form of cholera wherein
the results of serum are not salts
factory. This type of the disease
is referred to as the chronic type
and infected animals appear I'M
thrifty yet continue to eat normal
amounts of feed A large dose of
serum should be used in chronic
ally infected herds or herds that are
unthrifty, and when a liberal dose
is used the animals may not respond.
II is impossible by looking at
sick-.pig to make a diagnosis. In
order to arrive at well grounded
it is advisable to sacri- {
flee sick pig and hold a careful
post norton examination. The
lungs in the normal animal are of a I
light pink color. Frequently les
ions of cholera are noted in the d
lungs in the form of small dark red
scattered over the sur !
face of the lungs. If the animal is ,
suffering from pneumonia, large
areas of solid dark red tissue are |.
observed in the lungs. The kid !,
neys normally are of a dark red
color. but if cholera Infection ex-
lists they are frequently spotted with
small hemOrrhages which give them
the appearance of a turkey egg.
