ment was reported by federal authori.
ties to our state live stock sanitary
board, and the affected animals were
destroyed. It is possible that other
mares, showing no symptoms of the
disease at the time, have also been
brought In, and owners of breeding
stock should be on their guard. All
suspected cases should be Immediately
reported to the state live stock SAM.

operate in controlling the disease. T.
Dourine is a slow going disease of
breeding horses which is highly con.
tagious and often results in death
after months of suffering. 1t is caused
by a microscopic animal which is
transmitted from the stallion to the
mare, or from the mare to the stallion
only during service.
Stock breeders cannot afford to take
chances. Owners of stations should
/ not allow them to serve range mares
that have not been In Minnesota more
than one year, and owners of mares
should not patroniZe stations that
have come from North Dakota, South
Dakota or Montana within three years,
or any stallion whose breeding history
Is not we'll known.
There are three distinct stages in a
typical case of dourine.

FIRST STAGE. In the primary
stage, the first symptom noticed after
breeding is thick, sticky, odorless
and colorless discharge from the sex.
ual organs of either the male or fe-
male. These organs may also be
swollen, but the swelling. may easily
be overlooked by the owner, unless
he be very close observer. Sexual
desire on the part Of the stallion may
be Increased or decreased. Mares
urinate at short intervals and present
symptoms that are characteristic of
the heat period. The temperature
may be elevated, although this is not
always the case. Doughty swellings
may be present In the testicles and
along the sheath. The fore and hind
limbs may also be enlarged. The ap-
petite, as rule, remains unchanged
until the later stages, when it be-
comes irregular. The discharge from
the genital organs of the female has
tendency to accumulate on parts be-
low, removing the coloring matter of
the skin and leaving small, hairless,
white spots. u. ID. fr.N

SECOND STAGE. In the second
stage the skin and lymph glands be-
come diseased and the animal loses
flesh rapidly. 1t also loses control of
the hind legs and becomes lame. The
swellings on the body and genital or
gans become less sensitive and small
eruptions similar to nettle rash ap-
pear, usually on the neck, shoulder
and loins. The animal lies down a
great deal, and has more or less trou-
bic in getting up, on account Of the
increasing paralysis of the hind legs.

THIRD STAGE. In plain cases the
third or nervous stage may find the
animal unable to rise or stand unless
supported. Tho temperature may be
above normal at this time and the
appetite is poor and. irregular. The loss
OF flesh progresses rapidly, and slow,
aaaFy looking ulcers may become
Widespread over the body. Owing to
1heonse suffering. the animal Is usual
