French
Scientist Tracks Closely
Idaho Progress on Equine Cloning
May 29, 2003
MOSCOW, Idaho – French scientist
Eric Palmer sees an important future for cloning
in Europe’s refined world of competitive
horsemanship. The reason’s simple: most
of the top champions in dressage, jumping,
eventing, equitation
and similar events are geldings, castrated
males that are now genetic dead ends.
For Americans,
the direct comparison would seem to be the
remarkable gelding Funny Cide
that has already collected wins at the Kentucky
Derby and Preakness. He’s a favorite
to complete the first Triple Crown bid in 25
years with a win at the Belmont Stakes on his
home track next month.
For Funny Cide’s
fans, however, it may be anything but vive
le difference between
the U.S. and France.
The Jockey Club, which
regulates American thoroughbred racing,
bans cloning or any other reproductive
technology much more advanced than natural
service, the stallion mounting the mare.
In
Europe, athletic performance in competition
is what counts. Equine champions can come
from any breed. Unlike the racing world, where
a champion stallion’s
progeny are tested by age 3 or 4 on the track
and can then be retasked for breeding, Europe’s
champion horses take a decade or more to develop.
That undermines the ability to test the performance
of a stallion’s offspring. That produces
the irony that brings Europeans like Palmer
to America in search of a successful
method for cloning horses.
Palmer recently traveled
from his home southwest of Paris to Moscow,
Idaho, to visit scientists who are part of
a University
of Idaho-Utah
State University team that last year reported
the
horse world’s best prospects for
producing a cloned equine. “
The first teams who have published anything
in this area, one of them is the team of Moscow,
Idaho. And the first pregnancy that has been
presented comes from Moscow, Idaho, and I
think you
expect the birth in a short time,” he
said in April, basing his visit on a report
by Dirk Vanderwall in Colorado last summer.
The
team includes Gordon Woods, the UI veterinarian
and researcher who directs the Northwest
Equine Reproduction Laboratory on Moscow campus;
Ken
White, the Utah State animal scientist who
specializes in livestock cloning; and Vanderwall,
a UI assistant professor of animal science.
Idahoans have their own horse to ride in any
debate
about the potential for cloning throroughbreds.
Buddy Gil, an Idaho-trained gelding, made a
strong showing in this year’s Kentucky
Derby, finishing sixth behind Funny Cide.
Palmer’s
interest in cloning horses arose long before
the run for the roses earlier this
month. Long an academic researcher, Palmer
shifted gears to commerce and formed a company,
Cryozootech S.A. based in Sonchamp, France,
to rescue the genetics of gelded champion horses.
“
So now we come into cloning, why is cloning
an interesting business? It’s another
way to solve the problem of some totally infertile
animals. Among these infertile horses are all
the geldings, all the horses that have been
castrated. And some of them, after they have
been castrated, you find they are very, very
big champions. And their potential is being
a stallion.”
Cloning offers a tool to
turn back the clock to recreate the stallion
that became a gelding
that became a champion.
The performance of
the cloned stallion in athletic events
will be
less important than his ability
in the breeding shed to pass on his unique
carbon-copy DNA to improve traditional breeding
lines.
Palmer’s own stature in equine
science is unique. In 1990, he produced the
world’s
first test-tube foal produced by in vitro fertilization – uniting
egg and sperm outside the mare’s body
to ensure fertilization. It is a last-ditch
solution for infertile mares. His team produced
another test tube foal, and no one has reported
success with the technique since. Embryo transfer,
in which horse embryos begin life naturally
within valuable mares and are
then moved to less valuable surrogate dams,
has become routine. With embryo transfer, a
valuable mare can produce many more offspring
than she could otherwise.
And while artificial
insemination and embryo transfer has sped advances
in horse breeding, Palmer is excited about
cloning’s
impact.
“
If you can take one of these big champions
that has been castrated but is at the top of
the genetics, there is potential for improving
genetics and a business potential,” he
said.
“ I am working with people
in quantitative genetics. They made some calculations
according to the
type of populations and in some of the disciplines
like dressage, like endurance, and like eventing,
90 percent of the big champions are castrated
horses.
“
In this situation you can improve genetic progress,
accelerate genetic progress by 50 percent if
you are able to make stallions of these big
champions,” Palmer
added.
