4 THE BRUSSELS POST NOVEMBER 29 1978
Embryo transfer on farm now possible
Embryo transfers may now
be performed right on the
farm but according to. Dr.
Keit Bediri from Via Pax, the
whole concept has not been
pushed far enough.
Over 140 members of the
Huron County Holstein club
listened to Dr. Bediri tell of,
the advancements in the field
of non surgical embryo tran-
sfers, at their annual
meeting in Belgrave, Friday.
ThiS method of breeding is
not a riew concept. The first
`embryonic transfers were
490*, in Cambridge, England
it 90 with rabbits to deter-
mine if recipient mothers
could genetically effeci
embryos.
In the 1930's lab animals
were raised by this method,
and in 1951 the first calf was
born in an experimental
dairy herd. It was not until
1969-70 that more reports
concerning embryo trans-
plants were received.
"At present doctors are
finding a 90% success rate
for surgical embryo trans-
plants." Dr. Bediri said.
Dr. Bediri pointed out that
with the introduction of
exotic cattle in Canada re-
search has advanced con-
siderably.
"These breeds (exotic) de-
manded high prices. "said
Dr Bediri "They had ,to be
brought into Canada and the
second generation could then
be exported to the States
which did not allow for
importation of cattle from
`other countries."
Too Long
"The long quarentine
made it too long to wait for

the cattle to be bred and
calved. So cattle were super
ovulated and the eggs were
flushed out and placed in
recipient cows already in the
country." Dr. Bediri said.
The situation was ideal for
experimentation for those
who were willing to take the
risk, said Dr. Bediri. "What
would have taken years was
done in a much shorter time
-period."
For established breeds in
Canada this method of
developing herds would lead
to better stock and for larger
berth to be sold abroad. He
said.
It was discovered that
surgery was hard on dairy
cattle due to their build and
the amount of stress they can
stand. Therefore the method
of surgically implanting the
emb , vos was changed to a
lower lank k\ ith local an-
esthesia from the earlier
method of general anesthesia
and the cow turned on her
back.
• Non Surgical
"Now almost all com-
mercial companies are em-
ploying non-surgical
methods of embryo trans-
planting." said Dr. Bediri.
The process is extremely
simple. '1 he chosen cow is
programmed by the intro-
duction of hormones to cause
the ovaries to super ovulate.
"The ovaries swell and
must now not be confused
with cysts" Dr. Bediri said.
Dr. Bediri favoured
hormones taken from the
pituitary gland of pigs as
oppdsed to cows which is low

:in the required, hormone and
pregnant mares hormone
which is rich in horse protein
and could cause -problems.
The food and drug depart-
ment requires milk to be
withheld whenPMS
(pregnant mares) is used. If
the FSH (pituitary gland
homone) is used there is no
witholding.
Both the biological mother
and the recipient mothers
must be induced into heat at
the same time.
"The embryos may be
kept alive for one day, or
they can be frozen." said Dr.
Bediri. "We have a 65 per
cent conception rate and if
freezing occurs the rate
drops to 40 to 50 percent."
There are some draw
backs. Dr. Bediri pointed
25% of the embryos are lost
because of their fragile
nature.
"It is also expensive and
there are not that many
highly skilled people
available to do the job." said
Dr. Bediri. "Embryos can
only be frozen on the seventh
day."
"Some farmers could .pro-
fit from this procedure but it
is still an expensive pro-
position." Said Dr. Bediri.
Dr. Bediri suggested that
in the future there will be
small mobile units travelling
to the farms making Embryo
transplant accessible to the
average farmer.
There were questions
raised about the sexing of the
embryos before being im-
planted so that farmers
would not be wasting their
time with bulls when heifers
were the order of the day..
"Embryos can be sexed at
16 days by looking a sliver, of
tissue under the micro-
scope." Dr. Bediri salt'
"But that is too late for
implanting the embryo."
Sexing semen is a harder
problem. PH levels have
been checked. Electric fields
and gravity pulls among
other methods have been
used but there is still nothing
conclusive." said Dr. Bediri.
Bluevale
It forces the manure from the barn, through an underground
pipe to the storage area. As the manure enters storage area
from below, the outside surface forms a crust, which retains
the important nitrogen and potassium inside the pile and also
reduces the odor and fly problems. And manure is ready
for spreading, when you want it,
