Mr.. George Carter Editor, The
Evening Journal Wilmington, Del.
MvNDear Mr.. Carter ~ / wish to
comment on the article published In
The Evening Journal Of February
Is, entitled, vaccination Of Poul-
try Failed. This report emanating
from Milford, Del. is misleading be-
oause Il does not state the actual
facts in the case, as / shall endeavor
70 show later. Such an article will
have a tendency to discourage the
use OF the vaccine among persons
unfamiliar with this method OF
treating Deiaware's most important
poultry disease and. consequently. IT
Is believed that this explanation Is
necessary and probationary:
Roup Vaccine Not an Experiment
The method Of treating roup by
means OF a vaccine is not new, as
the article would lead the reader to
believe. This method of treatment
has been satisfactorily employed in
Ohio for moro than ten years and,
/ bv the means OF the vaccine, many
I Thousands Of birds have been pros
tectively inoculated against roup.
: The vaccine treatment was first ex-
tcnsively employed by Doctors
Brumley and Shook, Of Ohio state
| University. These workers have
published their results. dealing with
the vaccination OF many thousands
/ OF birds. In Ohio poultrymen wish
/ Ing to use the vaccine are required
/ TO pay for the treatment.
What Has Been Accomplished in
Delaware
The Delaware state Board Of
Agriculture. realizing that roup and
pox are very widely spread and
prevalent throughout the State, and
having available sum OF money
appropriated by the Legislature for
! poultry work. decided TO use a part
Of the funds to provide n vaccine
for treating roup and pox and to dis
tribute it free OF charge to poultry
owners OF the state. In carrying out
the project. the Department OF Bac-
| teriology and Animal Hygiene, Of
the University OF Delaware, has CO.
operated with the state Board Of
Agriculture. The work OF producing
| tie vaccine and distributing IT TO
poultry owners has been carried out
in laboratories OF the above-named
department, in the University.
7 The vaccine produced and used in
! Delaware has been made according
to the method employed by Doctors
Brumley and Snook which has given
such excellent results IN Ohio. In
the work carried on TO this time, in
Delaware. attempts have been made
10 check the results obtained from
the use OF TIE vaccine and to carry
on investigationai work, with the OBJ
iect OF obtaining data that will
prove OF value 10 other states desir-
ing TO take up the work OF poultry
disease-control
REPORTS of Poultry Owners
Each owner that has used the
vaccine in Delaware has BEEN sent q
questionnaire. which he was asked
to complete and return TO the uni
verslty. after lie has treated his
flock. Many owners have complied
with the requests and have sent re
ports from which the following
data have boen compiled. Some OF
the owners have not sent In theil
reports and. consequently. It Is i'm
possible to draw conclusions from
every instance whore the vaccine
has been used.
Reports were received showing
- Ia. ha
p OF $4,000 birds. Where tie diseas
existed in the flock at the time o
treatment. the death rate was re
duced TO O.6 per cent. AS almost al
