Technion Prof Aids World Milk Production

HAIFA — An estimated
10 percent of the world's 450
million ton annual produc-
tion of milk is lost because of
cow diseases.
Prof." Ram Sagi of the
Technion's Faculty of Ag-
ricultural Engineering, and
a team from Cornell Uni-
versity, Prof. Norman R.
Scott, William G. Merrill
and Roger P. Natzke, have
been studying the problem.
for some years, and have re-
cently received a $270,000
grant from the Bi-National
Agricultural Research
Fund to continue their re-
3earch.

A great proportion of the
diseases in question are of
the cow's udder. In the 20th
Century, through genetic
improvements, the milk
output per cow has been
greatly increased. In Israel
it amounts to some 10,000
kilos (22,000 pounds) a year
per cow. This necessitates
attaching milking
machines to cows for longer
and more frequent periods,
which, in turn makes them
more susceptible to udder
diseases.
It has been shown that
milking machines are in-
volved in spreading mas-
titis. Of particular inter-
est are those cases where
organisms are being
transferred by the milk-
ing machine from one
teat to another within the
same udder during the
process of milking. This
is referred to as "cross
contamination" and it is
estimated to be the case
for 50 percent of all new
infections.
Research has shown that
cross contamination be-
tween teatcups within a
cluster can be prevented if
mechanisms which result in
reverse flow are eliminated
or their effects reduced, that
is, insuring that milk and
air flow are always away
from the teats.

TEL AVIV (ZINS) — All
38 New Yorkers in the first
graduating class of the Tel
Aviv University's School of
Medicine passed exams
qualifying them for resi-
dency training in American
hospitals. Most of the stu-
dents enrolled for the four-
year program after they
were refused admission to
schools in America.
The Tel Aviv school was
chartered by the New York
Board of Regents with
headquarters in New York
and academic facilities in
Tel Aviv. New York State
has paid the Israeli school
$600 annually for each stu-
dent, in addition to the
$6,900 tuition paid by' the
students. Lectures and
seminars are conducted in
English but the students
starting clinical work in the
third year must speak He-
brew to patients.

Orthodox Roots

TEL AVIV (ZINS) — The
Baalei Tshuva movement in
Israel which brings secular
Jews back to Orthodox

Sales Meeting for
`Celebration 33'

NEW YORK — Repre-
sentatives of some 20
Jewish organizations that
will benefit from the pre-
miere showing of the movie
"The Chosen" on May 11 in
32 countries met in New
York last week to discuss
sales techniques.
The movie premiere is
expected to raise $50 mil-
lion for 20 educational
organizations in Israel. The
event is billed as "Celebra-
tion 33" coinciding with the
33rd anniversary of Israel.
Tickets for the event are
expected to cost $100, with
four sites charging $500.

The conqueror is re-
garded with awe; the wise
man commands our respect;
but it is only the benevolent.
man that wins our affection.

Although Jews have a tradition of maintaining their cultural
heritage, they also have the reputation of becoming an integral part
of community they live in. And Scotland is no exc eption.
Glasgow prides itself on having the only Jewish pipe-band in
the world. And one of the city's largest kilt-makers
is Jewish.
Scotland's most famous product is fine Scotch
xvhisky. And America's favorite scotch is J&B. We
carefully select the finest scotches and blend them for
smoothness and subtlety. The result is why we say that
J&B whispers.
No matter where your friends or guests come
tram, se-rve them J&B to
make them feel at home. -
