Virus Infects 60 Percent
Dairy Herds
HARRISBURG (Dauphin Co.)
Although 60 percent of dairy
herds across the nation are
infected with the virus, only 5 per
cent of BLV-infected animals
develop the fatal Bovine Lympho
sarcoma, according to a Universi
ty of Pennsylvania professor.
Dr. Robert Whitlock, professor
of medicine for Penn’s School of
Veterinary Medicine, spoke about
the Bovine Leukemia Virus and
its effect on animals to about 50
Pennsylvania State Grange mem
bers and guests who gathered at

the Grange’s Annual Farm Show
meeting Jan. 7.
The Grange invited Whitlock to
address the issue of BLV at its
Farm Show meeting because it is
an issue the Grange feels the state
Department of Agriculture should
address with some urgency, said
Julie Franklin, spokeswoman for
the Grange.
As its recent convention, the
Grange created policy to urge the
state Department of Agriculture
and the USDA to work toward
making Pennsylvania Bovine
Leukemia free. A goal that the
Grange feels is attainable and
would benefit Pennsylvania far
mers, Franklin said.
Holland, Germany, Denmark
and Austria have eradicated BLV
and the European Economic Com
munity has established a goal to
eliminate the virus. This goal once
achieved could restrict incoming
U.S. exports if they are not free of
the virus.
“The state and federal agricul
tural agencies need to adopt this
goal if Pennsylvania and all
American farmers are to compete
in the world economic communi
ty,” Franklin said. Currently, New
York is the only state with an
active, ongoing certification
program.
Bovine Leukemia Virus, a lym
phocytotrophic retrovirus, has not
been shown to cause disease in
man, but in Pennsylvania 33 per
cent of dairy cows are infected
with BLV and across the nation,
25 percent of dairy cows are
infected with the virus, Whitlock
said. Only 4 percent of beef cows
are infected with the virus.
Bovine Lymphoscarcoma,
caused by Bovine Leukemia Vir
us, is a cancerous disease of lym
phoid tissue which is always fatal,
Whitlock said. An “infected” ani
mal carries the virus and has deve
loped antibody to the virus but

may not necessarily be afflicted
with related tumors.
Whitlock said Bovine
Leukemia rarely occurs in animals
less than 2 years of age and more
commonly occurs in 4 to 8 year
old catde.
He continued to elaborate by
noting symptoms of Bovine Lym
phosarcome that farmers can look
for include weight loss and
decreased milk production. But
specific clinical signs depend on
which lymph nodes are enlarged
and are detachable through veter
inary examination.
Eighty percent of BLV cases
are transmitted from cow to cow -
“horizontal transmission,” Whit
lock said. Tranmission of the virus
can occur in a number of ways
including hypodermic needles,
gouge calf dehorning without
washing and disinfecting instru
ments, ear tatooing instruments,
biting insects especially horse
flies and rectal palpadon with a
common plastic sleeve presents
some risks. In-utero or vertical
transmission occurs in 6 to 20 per
cent of calves bom to infected
dams.
Although milk contains virus
particles and may infect calves
without antibody, when given to
calves with colostral antibody it
rarely results in BLV spread, he
said.
However, bloody milk repre
sents a greater risk of spread since
it may contain more BLV infected
cells.
Efforts to control the virus
include raising calves from nega
tive dams; feeding colostrum from
BLV negative dams to calves
from BLV positive cows; cleaning
and disinfecting dehorning,
castration and latoo instruments;
using individual needles for vacci
nations and separate rectal sleeves
for each examination if infected
cows remain on the farm.
