Hebrew-U Discovery Licks Virus

ness to receive instruction by the
university scientists on bow to
implement the new method.
Newcale Disease, Prof. Perek
explains, is an epidemic disease
which was first determined in 1926
by British scientists in Newcastle
on a flock of birds imported from
India. The infection, caused by a
virus, affects the respiratory tract
and the nervous system of the
birds. The disease appears with
varying strains, from mild to
severe strength, the latter killing
up to 100 per cent of infected
flocks.
For some time it had been
known from laboratory experi-
ments that UV radiation kills
NDV in a matter of only 30 sec-
onds, but no applied research on
poultry had been made until the
Hebrew University scientists start-
ed their research project. They
were prompted also by the fact
that after the Six-Day War, a se-
vere strain of the disease appeared
in Israel, possibly coming from
neighboring countries, and that
the disease was spreading in vac-
cinated as well as non-vaccinated
flocks, especially affecting young
chickens from 10 days of age
until 10 weeks.
During the first days of their
life, baby chickens may withstand
a slight infection of Newcastle

Disease Virus by means of a cer-
tain amount of antibodies which
they receive from their immunized
mother through the egg yolk, but
they gradually lose these inherited
antibodies. Until the age of 21-26
days, chickens are not able to pro-
duce sufficient antibodies in their
tissues by vaccination in order to
counter a massive infection. In
addition, it appeared that the im-
nmnological response of young
chickens with inherited anti-
bodies might be interfered with
by early vaccination. The chick-
ens may normally be exposed to
massive infection from the out-
side with the NDV being carried
through the air as far as 4 kilo-
meters from infected to non-in-
fected flocks.
Since UV radiation is widely
used in bacteriological labora-
tories and in food packing stations
in order to avoid contamination
of the air by bacteria, fungi and
virus, Prof. Perek and Dr. Heller
decided to try continuous radia-
tion of chickens in their houses
by using UV lamps of 2530 Ang-
strom wavelength.
Prior to the actual NDV experi-
ments, however, they wanted to
establish whether the birds might
be affected by continuous radia-
tion itself, i.e. whether it affects
their growth, health or feed effi-
ciency. In three of those advanced

experiments an increase in weight
gains was note d, compared
to the weight of chickens in non-
UV-exposed flocks. In a fourth ex-
periment, no differences in weight
gains could be observed, but the
feed efficiency of the UV-radiated
group was 7 per cent higher than
in the non-exposed group. In all
four experiments, the feed effi-
ciency was significantly better,
by 5-7 per cent, than in all groups
which had not been exposed to
UV radiation. Moreover, it was
found that the eyes of the chick-
ens in the LTV-exposed groups
were not seriously affected by
radiation, and that the birds kept
on eating and drinking normally.
The bacteria in the air were
counted by cubic meters, and a
highly significant difference was
found. In the ITV-radiated rooms
were 100-1,000 times less bacteria
isolated from the air than in non-
treated rooms.
As a followup to the research,
the scientists have recently per-
formed several successive experi-
ments by using UV radiation in
chicken houses. In the experimen-
tal rooms, UV radiation was per-
formed continuously on the chick-
ens, from day-old chicks to 60
days of age, while in the adjacent
control rooms, no radiation was
installed. In each of the rooms, a
cage containing NDV-infected
birds was placed high on the wall.
The birds in the cage sneezed and
coughed, spreading the drops from
their beaks all over the room.
When they died, they were re-
placed by new infected birds in
the same cages. The experiment
lasted 22-26 days until the control
groups died by NDV infection. No
birds in the radiated groups
showed signs of the disease and
none of them died.
A total of 700 birds were used
in all these experiments.
The research, Prof. Perek says,
may prove that exposure to UV
radiation of broiler chickens up
to 9-10 weeks of age will afford
pretection to airborne infection
of NDV. He has now decided to
continue the team's experiments
also with other viruses affecting
the respiratory tract of birds, e.g.
Laryngo Tracheitis, Mycoplasma
Galicepticum, infectious bronchitis
and other viruses transmitted by
air.
According to Prof. Perek, the
scope of the achievement may be
of a highly applied nature. The
cost of exposing chickens to UV
radiation will reach only 2.5 ago-
rot (less than one U.S. cent) per
head over a period of 10 weeks.
Multiple - vaccination costs the
farmer much more for vaccine
and labor, approximately 30 ago-
rot (some nine cents) per head.
An additional positive factor, he
points out, is the additional feed
efficiency and weight gains in
chickens, obtained by UV radia-
tion.

isters.

Minister-Without-Portfolio Israel
Galili, chairman of the govern-
ment's settlement committee said
"Our villages in the Golan Heights
will have to organize themselvet
for a new situation" following last
week's battles with Syrian forces.

Finance Minister Pinhas Sapir
said at a press conference that the
government will probably have to
impose new taxes and take other
fiscal measures to combat infla-
tion, including possibly, rationing.

He said defense expenditures
were increasing rapidly and that
25 per cent of the population is
