FORT COLLINS, Colo. - Cat
tlemen and dairymen these days
are speaking a new language.
Today there is talk of genetic
engineering, embryo transfer,
embryo splitting, cloning, selec
tive sexing, and in vitro (test tube)
fertilization.
Within the past few years
significant developments have
brought a wave of new technology
to the cattle and dairy industry.
Freezing of embryos has become
an economic proposition. A
technique for splitting embryos
has been developed. Embryo sex
determination is making ad
vances. The introduction of a new
estrus synchronization product
promises to aid the practice of
embryo transfer at the producer
level, and it has brought renewed
interest in artificial insemination
by making A.I. more practical for
beef and dairy producers.
w Putting all these developments
together, experts foresee a
revolution in the production of beef
and milk in the next decade.
“State of the Art”
What is the current “state of the
art” in cattle breeding?

current status of genetic technology?
before a Congressional sub
committee, current cattle
breeding technology is somewhere
“in the middle” not yet close to
the cloning of a super animal, but
yet a lot more advanced than many
realize.
Dr. Peter Elsden, manager of
the Embryo Transfer Unit at
Colorado State University, states
that embryo transfer already is
“well out of the lab.”
Embryo transfers, according to
Dr. Elsden, are occurring at a
rapidly-increasing rate. Dr.
Elsden cites figures showing that
approximately 10 years ago breed
societies registered 20 cows from
embryo transfer, and now the
number is well oyer 100,000.
Another indication of the growth
of this practice is the an
nouncement of a scheduled
transfer of 300 frozen cattle em
bryos from the U.S. to recipient
cows in Venezuela, one of the
biggest such experiments to date.
Rapid Genetic Progress
Dr. Elsden states that embryo
transfer will increase the rate of
genetic improvement in herds,
first for the registered breeder but
later for the commercial man as
more high-quality animals become

available for sale. And, there will
be more rapid test progress at the
experimental research level.
Describing the transfer
procedure. Dr. Elsden explains
that a genetically-superior animal
is treated with stimulant hormones
to induce growth of many follicles,
resulting in the release of more
than one egg at ovulation, perhaps
5 to 25 or more. The donor animal
is then bred AJ. to a selected
superior sire. Several days
the embryos are non-surgically'
collected. The embryos are then
non-surgically (or surgically)
transferred into recipient animals,
who carry the embryos through
gestation.
Embryo transfer is a means to
an end, says Dr. Elsden. There is
much greater utilization of
selected females. It is a deliberate
matching of selected superior sires
to superior females, thus
producing many more calves from
those superior females. Using
embryo transfer, a female with
known superior beef or dairy
characteristics can produce far
more offspring than the usual one
calf per year.

embryos, the producer must
synchronize the estrus cycle of the
donor animal and the recipient
animal. They must be at the same
stage of their heat cycle. When
embryos are collected, there must
be an adequate number of syn

plantation.
A recent development in this
respect is the introduction of a new
estrus synchronization product by
CEVA Laboratories, Inc.
Synchre-Mate-B, FDA-appro
ved for use in cycling beef and

interest in artificial insemination
and genetic herd improvement.
