Ell at the meeting OF the Board oil
Agriculture and Forestry held Fri
day afternoons:
beg to report to you on my trip
to Washington, ID. c.. for the purpose
of attending the annual meeting of
the Interstate Association of Live
Stock Sanitary Boards held at Wash
ington, ID. c., Sept. 18th to 18th. and
of the international tuberculosis
Congress held at the same place from
Sept. 22d to Oct. 18th of this year.
I left Honolulu on Sept. list. arriv-
ing in San Francisco Sept Sth and
proceeding without, delay to Wash
ington, arriving there on the 18th
of September.
The Interstate Association of Live
Stock Sanitary Boards, of which
was one of the charter members, OPP
sned its twelfth annual session at
the Hotel Raleigh in Washington on
the morning of Sept. 18th.
The meeting was unusually well
attended on account of the American
Veterinary Medical Association hav-
Ing just finished its annual meeting
at Philadelphia, as the result Of
which large number of State veter-
mary officials were present who
might not otherwise have been able
to come the long distance of the Wes-
tern States to Washington, d. C.
The program covered large num-
Der of subjects, of which, however,
I shall only mention those which are
of interest to this Board.
Hog Cholera
This disease, which probably caus.
es greater loss to the live stock in
dustry of the United States than any
other animal disease, has been inves.
tigated by the United States Bureau
OF Animal Industry for great mum
Der of years. Up to quite recently
in fact up to within the last year OF
two, this disease in connection will
swine plague has been supposed to b,
caused by specific bacillus know
as the Hog Cholera Bacillus" Will,
swine plague, which almost invari
ably accompanies hog cholera, ha
been supposed to be caused by tn
swine plague bacillus.
This theory which has been accept
ed by all of the leading investigator
of the world. has now been complete
~ overthrown, 1t having been dem
onctrated conclusively that the no
cholera and swine plague bacilll ar
of entirely subordinate Importance a
causes of these diseases and that tn
tribe infectious agent is an ultra-mt
croscopic organism. that is an organ
ism which cannot be demonstrate
by means OF the strongest microscop
and which is able to pass throug
the finest Pasteur filters. This me-
discovery naturally leads to the aba
doning of all Investigations whic
were based upon the production of
serum or antitoxin manufacture
with either the hog cholera or tn
swine plague bacillus as basis.
1t is a well-known fact that hos
which have recovered from an attaC
OF hog cholera are completely In
mune when subsequently exposed
the same disease, and this. In conne
ton with the established fact Thu
the filterable virus is present in Il
blood Of hogs sick with hog choler
has led the Bureau OF Animal Indu
try to the preparation of seru
which has been used successfully
immunizing hogs against hog cho
era. Numerous experiments ha'
been carried out by the Federal
well as by State veterinary ofiicia
and these experiments have demo-
strated that the method is simpl
cheap, and reliable.
In herds which had been expos
to the disease but were apparent
well at the time OF the treatme
only four per cent. of the treated a
imals died, while approximately
per cent. of the untreated anima
succumbed. The Bureau of Amin
Industry estimates the cost of [
serum when manufactured wi
strict economy at 25 cents per hog.
The economic Importance of Il
discovery can hardly be over-estin
tie dand nearly all OF the princiI
hog-producing States of the Uni
are now establishing plants for t
manufacture of the serum, which
to be distributed at cost. The L
reau of Animal Industry has tax
the precaution to patent the proc
in order to prevent 1t from fall
into the hands of the great serl
and vaccine manufacturers.
