Studies to. determine the effect
of VEE vaccine on the central
nervous system of horses were
conducted at Denver, Colo, and
Ames, lowa by the Veterinary
Sciences Research Division
(VSRD) of USDA’s Agricultural
Research Service (ARS). The
brains and spinal cords of 45
horses were examined grossly
and microscopically.
“Although mild, transitory
effects in tissues of the central
nervous system were observed
following vaccination, no
evidence of damage to either the
brain or spinal cord was found in
horses examined between 10 and
49 days following vaccination,”
Dr. Paul DeLay, VSRD Director,
said.
“Some of the horses in the test
developed low fever and ap
peared slightly ill following
vaccination, but all of these signs
disappeared after 10 days,” he
said.
These tests confirm our fin
dings in the field last year when
over 2.8 million horses were
vaccinated in 19 States and the
District of Columbia,” Dr.
Francis J. Mulhern, Ad
ministrator of USDA’s Animal
andPlantHealth Service (APHS)
said. “With these favorable
results with the vaccine tests

under controlled conditions, we
again urge all horse owners to
vaccinate for VEE, because this
virus could break out anywhere
in the country.”
Experiments still in progress
will evaluate the effects of the
vaccine on pregnant mares and
young foals. Tests are also being
conducted to determine the
quality and duration of im
munity, Dr. DeLay reported.
Although VEE was confirmed
in only 26 counties in southern
Texas last year, animal health
officials emphasize that the
disease could break out any place
m this country Use of the VEE
vaccine, available through
veterinarians, is the only means
of protecting horses against
infection.

Joins “Iron Grandma’s”
The Holstein-Fnesean

What’s new in
herbicides?
AAtrex
4L. It pdurs.
New AAtrex 4L is the brand of atrazine that pours.
This special liquified product controls most annual
grass and broadleaf weeds in corn and sorghum
right up to harvest just like AAtrex wettable
powder.
But with AAtrex 4L there’s no premixing.
You simply shake and pour it directly into the tank.
And apply in a minimum of 10 gallons of water
per acre.
Easier handling. A minimum of agitation.
And less chance of nozzle and screen plugging.
That’s AAtrex 4L. And we have it. In 1 gal. jugs
and cartons.

Vaccination for eastern and
western types of encephalitis
does not provide protection
against VEE.
VEE is spread from horse to
horse and from horse to humans
principally by bites of
mosquitoes. Animal health of
ficials urge that all horses not
vaccinated last year be vac
cinated before mosquitoes
emerge. Regions considered
“high risk” include Texas and
adjoining States, Gulf Coast
States and States adjoining
Mexico. Since the virus was
found in Texas, that State
remains under Federal
quarantine—requireng vac
cination of all horses before being
transported outside Texas.

production that spans a lifetime
of 12 years, she has produced
nearly 100,000 quarts of milk!
“Pattie” joins a select group of
over 500 cows of the breed to be

by the Holstein Association. Her
actual lifetime output stands at
