1.Question: When you
say "The use of frozen semen and fresh-cooled
semen showed us the true facts of canine breeding.
Many testing methods that seemed to work only
appeared so due to the extreme long life of fresh
semen in the bitch," what do you mean?
Dr.Hutch:
Basically, fresh semen lasts 5-6 days. Colorado
state has found live semen ELEVEN days after
breeding. This made up for a lot of our mistakes.
Once we started using fresh cooled and semen,
which last only a few days or hours, suddenly
things that seemed to work in the past no longer
seemed to work. Now with prosterone testing,
we can get 83 percent conception rates with
FROZEN semen....
2. Question: Bitches
who keep missing. Several people asked a variation
of this question: I have tried a number of times
to breed my bitch, both with natural breedings
and with AIs. She has missed repeatedly. Where
do you start when trying to understand and resolve
this problem?
Dr.Hutch:
Basically there are only SIX reasons a bitch
misses, and we run around testing thyroid and
doing cultures, which are really only minimal
reasons for failure. First, is the male sperm
good. Second, did she ovlulate. Three, was semen
put in at the right time. Four, did semen get
to egg. Five, did fertilized egg implant. Six,
did placenta develop enough to maintain (the
pregnancy). We have to work our way through
the list to determine what the cause was. What
we do is, first of all, have the male semen
evaluated. That is NOT saying there is a drop
of sperm on the slide, there is sperm or no
sperm. Normal sperm evaluations consist of 10
million sperm per pound of body weight, 80 percent
motility, less than 20 percent abnormal, and
if your male sperm meets those criteria, probably
it's not the problem. The other five problems
have to do with the bitch herself, and progesterone
testing the DAY of ovulation is the day her
progesterone goes above 5 nanograms. Even though
she has this three week-plus heat cycle, there
is a three to four day window we have to hit
that varies from bitch to bitch. With progesterone
testing, we can be sure the semen is put in
at the proper time no matter what type of insemination
method we are using. In the bitch, the semen
is pumped up into the uterus....so outside ties...
poorly done AIs... that don't deposit the semen
in the cervix, which is located in the abdomen
above the bladder, prevent sement from being
drawn up into the uterus. As bitches age, they
get cysts within their uterus which can obstruct
the pathway - a good reason in an older bitch
for considering a surgical insemination. Conception
takes place in the Fallopian Tubes regardless
of the method of insemination. An older bitch
is any bitch over 5, by the way; several of
you asked. The fertilized eggs are then released
into the uterus, but don't implant until day
17-18 after ovulation. So if there are uterine
lining problems, we either don't have implantation
OR...the placenta, which actually grows into
the lining of the uterus, can't grow or be maintained,
and the puppies are reabsorbed. It will develop
as the night goes on, how to detect some of
these problems. When a bitch ovulates, whether
we breed her, don't breed her, or pretend she's
not in season, the progesterone HAMMERS the
uterine lining for sixty-plus days. The progesterone
level is NOT affected by pregnancy. In the cow
for example, if the uterus does not get communication
from the fertilized egg by day 16, the whole
process starts over again. In the bitch, you
don't have that luxury. Even though the bitch's
body produces the progesterone, the progesterone
is inflammatory to the uterine lining, so that
after a heat cycle, the bitch's uterus is never
as healthy as it was before the heat cycle.
So we go from a normal uterus... and this start's
with the first cycle of her life...to an endometritis
to endometrial hyperplasia, which some of you
have been asking about - this is when the uterus
starts to thicken and we start to get bubbles
in the lining of the uterus - these changes
affect the uterine lining so much so that eventually
the uterus cannot control the bacteria, and
the ultimate end stage is pyometritis. So, in
the bitch... So breeding back to back... or
even back to back to back to back....this is
WHY it's such a crime we don't have Cheque drops
on the market now, to preserve the bitch's uterine
lining. Several of you have asked when they
will be back on the market....one company promised
by this spring. Pyometritis is a hormonal disease,
of which the infection is only secondary. Cheque
drops is a wonderful product.... that was Miberolone...a
male hormone derivative that could safely delay
a bitch coming in season for up to two years.
Ovaban is a different product, same as human
Megace. These are progesterone products, the
exact hormone we are trying to preserve our
uteruses from.We should NEVER use ovaban or
megace in a bitch we want to breed in the future.
Cheque drops are NOT progesterone.We could show
bitches, we could field trial bitches, and still
have a uterus that was only 2-3 years old in
a five year old bitch!Cheque drops preserve
and promote fertility by preserving the uterine
lining. The average bitch after going off Cheque
drops came in after 70 days. The biggest problem
is they had to be given every day. Pyo is EXTREMELY
rare in a young bitch; remember, bitches do
not go into menopause. Only humans and gorillas
do.When a bitch's reproductive life is over
she should be spayed.It's very good to spay
an older bitch, because the uterus is always
going to be hammered by progesterone every heat
cycle. Side effects from Cheque drops: One percent
tear from the eyes; they tend to muscle up and
get morecoat, because it's a male hormone derivative.
The biggest misunderstood side effect, however,
was mucous around the vulva... like a puppy
vaginitis. Unfortunately, many veterinarians
diagnose any goop around the vulva as pyometritis.
Cheque drops PREVENTED pyometritis by protecting
the uterine lining. Cheque drops were only removed
from the market because they were not profitable
enough. There was no medical reason. Case History,
STUD DOG:. Proven stud dog who was recently
diagnosed as being sterile. .He is being treated
for a prostate infection using Orbax 68mg for
2 weeks. Vet found prostate normal on exam but
lots of bright red blood in semen. Will we be
able to restore fertility? Thoughts? DrHutch:
Male dogs age the same as human males age...
with a change in the type testosterone being
produced from the testicles. One of the effects
in the dog is benign prostatic hyperplasia (bigger
prostate). This is a routine happening in all
males over six years of age, being especially
prominent in the Doberman. Unfortunately, it
is misdiagnosed as an infectious process by
many veterinarians. So they often times are
treated by antibiotics, often with no subsequent
improvement with often the drastic suggestion
that the male be neutered. The PROPER treatment
is one of hormone therapy, using one of two
products: either Ovaban, that dreaded product
we wouldn't use in the bitch, or Proscar, which
is finasteride, which is a human product. These
work by countering the change of the testosterone
causing the prostate to shrink back down to
a normal size, stopping the bleeding, making
the dog reproductively normal. A dog with a
prostate INFECTION will have PUS in the ejaculate,
not blood. A dog with a true prostate infection
runs a fever, or shows many of the signs of
a bitch with pyometritis. Prostatic cancers
do occur in the dog, but are more common in
neutered dogs than in non-neutered dogs.
3. Question: Is is safe
to breed a bitch the next season after stopping
the Cheque.
Dr.Hutch:
Absolutely. It's suggested not to skip a season,
because we have been preserving the uterus from
the effects of progesterone; what would be the
benefit of exposing her uterus to two monts
of progesterone? Progesterone's effect on the
uterine lining is the reason why bitches six
and over have a 33.3 percent less chance of
conceiving than bitches under 6 years of age.
Back to the case study.... neutering does not
cause prostatic cancer....but it does not prevent
it. I'm getting many questions on Ovaban. Ovaban
will decrease the amount of blood and prostatic
fluid, not actually INCREASE sperm. The treatment
is a daily treatment for 3 weeks; after that
once a week indefinitely. It's a control medication
countering the aging and hormonal changes of
the testicle. 80 percent of a dog's sperm production
is based on the size of their testicles; that's
where we get the 10 million per pound of body
weight. Changes can take place due to cortisol,
from STRESS... we don't appreciate the effect
of stress on the reproductive health of our
dogs. Interestingly THYROID has little to do
with the reproductive health of our dogs (males)a
study at Michigan State took male dogs and completely
destroyed their thyroid and found it had no
effect on sperm production. The thyroid is probably
not a consideration in a dog with a low sperm
count. We should look for hormonal problems
in the body, infection problems in the body.
And in many dogs, immune and genetic problems.
Thyroid in bitches also has very little importance
in reproduction. The main sign of a reproduction
problem related to female hypothyroid is they
don't come in season. There is no proven benefit
of giving thyroid to a normal thyroid individual,
reproductively. My main concern with thyroid,
depending on which of the three types of hypothyroidism
it is, is the immune-mediated type has genetic
implications. If they have even SOME thyroid,
that is probably all that is needed to maintain
a pregnancy. Studies out of Florida show bitches
with even ZERO thyroid function, did have trouble
maintaining a pregnancy and had a type of dwarf
puppy, but bitches with ANY thyroid function,
that come into season, thyroid will probably
not cause any further problems. So once you've
proven your bitch's thyroid is normal, there
is no reason to be going to six different veterinarians
to have her retested. Save your money, take
Dr. Hutchison to lunch
4. Question: What about
the dreaded mycoplasma?
Dr.Hutch:
Unfortunately, an article published in the early
90s blamed mycoplasma for infertility in males,
bitches aborting their puppies, husbands fooling
around with their secretaries. We as dog people
jumped on this like there was no tomorrow. Mycoplasma
is a normal organism at all body openings. A
routine culture of a bitch's vaginal tract will
show strep, staph, e coli, pastuerella, and
mycoplasma. The vaginal tract is not sterile
so routine culturing of a normal, healthy bitch
is totally unwarranted. You need to appreciate
the purpose of normal flora or normal bacteria:
they keep the BAD bugs out so a routine culture,
that shows mycoplasma, e coli, and strep, is
not a cause for treatment but a cause for celebration
because the bitch is normal
5. Question: What about
bitches who did not become pregnant before antibiotics,
but do afterward?
Dr.Hutch:
Putting on bitches on antibiotics pre-breeding
actually makes them more prone to infectious
disease by killing normal organisms, especially
when we use the GOOD drugs like Baytril. Occasionally,
we may see a bitch with an infection... but
there will be signs of that infection - redness,
abnormal discharge, smelling - just like if
you have an infection in your ear, you're not
going to not know it. Bacteria does not equal
infection. When we see problems with mycoplasma,
for example, it is not the mycoplasma that caused
the problem. Mycoplasma only took the opportunity
of the infection, just the same as the staph
on the skin causes a hot spot because the dog
has fleas, for example. Most of the individuals
that see who do have mycoplasma infection, would
not have been prevented by a routine culture,
as the primary problem was stress, steroids,
or other types of immune deficiency. They are
only secondary problems. Something like pyometritis
is not caused by routine bacteria; the normal
bacteria were allowed to flare up by the inflammation
of the uterine lining
6. Question: Isn't it
true that an e coli infection can be passed to
the puppies in the birth canal, causing fading
puppies and the loss of the whole litter?
Dr.Hutch:
In normal healthy puppies, no. Think of puppies
like the lions surrounding the antelopes looking
for the weak ones. If a puppy is stressed, unhealthy,
otherwise compromised, then the e coli can flare
up but it's not because we allowed the e coli
to be there, it's because we allowed the puppy
to be uhhealthy. We cannot sterilize vaginal
tracts no matter how many antibiotics we give
because air goes in, air goes out. Just because
there is vaginal bacteria does not mean there
is intrauterine bacteria (bacteria in the uterus).
I want to say I LOVE LOVE LOVE these questions!
7. Question: Can't these
bacteria be transmitted to the stud dog?
Dr.Hutch:
The male HAS all of these organism, so no, they
are NOT contagious. This is why one of the most
absolute crazy things I have ever heard of,
is people treating their whole kennel because
they had one dog with mycoplasma. This would
be the equivalent of treating your whole kennel
because one dog had a hot spot. Every dog has
this. It's not contagious. Brucellosis.... is
a whole other world. Brucellosis is NOT a normal
organism of the male or the female. Brucellosis
is a very serious disease that all bitches should
be tested for every time they are going to be
bred, and males should be tested for every six
months if they only breed a negative female.
Brucella bacteria can be passed through all
body discharges, not just through breeding,
so even individuals that have never been bred
but who have been to a show, a kennel, a field
trial, need to have a negative brucellosis test.
Brucellosis is not common, but because it is
extremely deadly... I myself consulted with
a kennel a few years ago who put down 26 dogs
because of an infected male they brought in.
It is a serious disease which is primarily associated
in the bitches with aborting puppies, and in
the male causing inflammation of the testicles
and subsequent infertility. It is at this point
not curable to the point of returning to reproduction.
Do not wait until the last minute to have your
brucella test run becasue the slide test run
by veterinarians in their office, actually made
from sheep brucellosis, one dog out of five
has a false positive. Even with AIs, you can
protect the male, but not the female, from a
dog who has brucella. Because you put the prostatic
fluid and ejaculate into the bitch, along with
the brucella. When we freeze semen, it is critical
to us to be certain the male is negative for
brucellosis, so we aren't preserving these bacteria
for a thousand years! Most dogs (with brucellosis)
do not have to be put down, but they must be
neutered and put on antibiotics for 4-5 years.
And it is transmissable to humans too. These
questions are SO GREAT... they are fabulous!
8. Question: Herpes?
Dr.Hutch:
Herpes is not the same as brucellosis. It is
part of the kennel cough complex. Any dog who
has been to a show or a training class probably
has herpes virus. Herpes virus is common. That
is why it is rare having a problem with it.
Herpes virus is only deadly to puppies during
the first three weeks of life, because a newborn
puppy's average body temperature does not reach
100 degrees until 3 weeks of age. If the bitch
has never been exposed to herpes, and has no
antibodies to pass through the colostrum to
the puppies, the puppies could be affected.
Once a bitch has a litter with herpes, she will
have the antibodies to pass through the colostrum
to the next puppies, so they will be protected.
Many people believe that a bitch should be taken
to shows etc so they are exposed and have the
protection to pass on to their puppies. Puppies
can be infected in utero, through the vaginal
tract, or by other dogs coming to sneeze on
them. Isolation is a good idea for the first
three weeks. Treatment for herpes: raise the
body temperature to 100 degrees, herpes goes
from being a deadly to virus to causing nothing
more than a minor cough.
9. Question:
Comparing AI methods Can you compare the success
rates of fresh chilled vs. frozen semen, and surgical
implant vs AI vs transcervical insemination?
Dr.Hutch:
The type of insemination method depends on two
things: Age of the bitch and health of the semen
you put in. Unfortunately, a misnomer exists
that the transcervical insemination replaces
surgical insemination. This is totally false.
Transcervical insemination improves upon VAGINAL
artificial insemination, it does not replace
the surgical. In a regular AI, vaginal, the
semen is deposited at the entrance to the cervix,
the tie is simulated. often by taking a rubber
glove and stroking the vaginal tract, which
causes oxytocin release. which causes the semen
to be pumped up to the uterus. So we know compromised
(frozen) semen, which is weaker and will only
live about 12 hours, needs to be deposited into
the uterus. Conceptions rates from frozen semen
put in vaginally are 11 percent Conception rates
from frozen semen put into the uterus are 83
percent The transcervical is taking an endoscope,
visualizing the entrance to the cervix, and
putting a catheter through the cervix and putting
the semen into the uterus. It does not require
anesthetic; the bitch just stands there. In
our practice we just watch it on television...
better than watching Oprah. The drawback to
a transcervical insemination is you don't get
a chance to evaluate the uterus. In a surgical
insemination, I have the uterus in my hand.
I can feel for cysts, I can visualize where
to put the semen. In many cases, by breaking
down cysts, I can take conception rates from
zero percent to 100 percent. Using fresh semen
in a young bitch is still a regular vaginal
AI. Compromised semen which is either poor quality
semen, fresh cooled semen, or frozen semen,
in a young bitch, should be transcervical insemination.
Using poor quality semen in a bitch 4 and a
half to five years or older, you want to do
a surgical insemination so the uterus can be
evaluated. A surgical insemination is always
your greatest chance of having puppies.
10. Question:
Do we need to spin down the semen for a transcervical
insemination?
DrHutch:
Since the uterus only holds less than a teaspoon,
we will oftentimes centrifuge the semen so that
the whole volume will stay in the uterus rather
than running out through the cervix. Because
the cervix is open in a bitch in season, bacteria
can go back and forth into the uterus, so the
transcervical insemination does NOT introduce
more bacteria than normal into the uterus, no
matter which insemination is used, including
natural. Conception occurs from all of these
in the same place, the Fallopian tubes, so the
method of insemination does not alter the location
of the puppies in the uterus, the lack of ease
of delivery, or positioning of the puppies.
11. Question:
What part of the ejaculate is the semen in?
DrHutch:
The male ejaculates in three distinct fractions.
The first fraction just cleans the pipes. The
second fraction contains the sperm; that's the
part that should look milky and thick. You stop
collecting when you see the prostatic fluid,
which looks like water. Volume is not important;
no one has a trophy for collecting a quart of
dog semen.
12. Question: How is
a surgical AI done?
DrHutch:
A surgical insemination is a minor procedure
that is done under an anesthetic. I use propofol
and sevothane, the same anesthetics we use for
c-sections, for our surgical Ais. The procedure
lasts approximately ten minutes. I make an incision
into the abdomen, like a mini mini spay incision
- - unless I sneeze, then it gets bigger - then
I isolate the uterus in my hand. The semen is
injected into the uterus using a 22 guage needle,
the same size needle used for vaccine. This
will not negatively impact future breedings.
It is SO COOL because I can see the uterus fill
with the semen; it's like watching the Discovery
Channel. I put in three stiches, five staples,
the whole procedure from the time she walks
in the door is less than an hour.
13. Question: How long
does frozen semen last, stored?
DrHutch:
Frozen semen lasts stored, probably forever.
It uses minimal energy when it's stored in the
liquid nitrogen at minus 322 degrees F. We had
a litter recently from semen that had been stored
25 years, it looked just as good as the day
it was frozen. It was great to see the sperm
swimming around again, happy to be warm! The
way we package our frozen semen is by the number
of normal live sperm cells per dose. A dog with
a great sperm count may get multiple multiple
breedings out of each collection... a dog with
lower sperm count may get one. We calculate
our dose so that each breeding has a set number
of live normal sperm, rather than by volume
or by a set number.
14. Question: When there
is a poor semen sample, is there a way to isolate
the viable sperm?
DrHutch:
We don't worry about the abnormal sperm, other
than mathematically eliminating them, because
abnormal sperm does not cause abnormal puppies,
so there is no reason to eliminate them.
15. Question: Oxytocin
(Pit shots). Can
you discuss the proper use of oxytocin injections
during whelping? It seems that many breeders use
oxytocin early on in the whelping process, when
they feel it isn't progressing fast enough.
DrHutch:
A puppy in the uterus has only two elements
maintaining its oxygenation and life, one being
the heartrate of the puppy, two being the blood
pressure from mom to the uterus. The whole goal
in whelping is to maintain vital elements. Oxytocin
I use in a very specific manner. If you've gone
three hours without a puppy, I use one dose
of oxytocin. My dose of oxytocin is two units
per ten pounds of body weight. Oxytocin is normally
20 units per ml; I never use more than half
an ml, no matter how big the bitch is. I give
one injection; if nothing happens, I give a
second injection 20 minutes later. If nothing
happens, I go to a C-section. If you get too
much oxytocin at a time, you will cause the
puppies not to be expelled from the uterus but
shrunk wrapped IN the uterus. The two injections
of oxytocin actually increase the blood pressure
to uterus which is beneficial to the puppies.
If we keep giving them, we LOWER the blood pressure
to the uterus, which robs the puppies of oxygen.
Using calcium with the oxytocin... now that
we can monitor calcium levels in our practice
I do not normally give calcium if the bitch
is normal, because it causes the heart to slow
down. If I need to give calcium I now use Calsorb,
an oral gel that is absorbed almost as quickly
as injectable. I can give it in small amounts
more often, and don't have to worry about the
side effects of injected calcium. To clarify,
my standard protocol (with oxytocin) is two
injections; if two don't do it, two, four, ten,
twenty, is not going to do it. In most cases
I keep score by how many live puppies I deliver,
not how many C-sections I avoid. I wait three
hours from the last puppy. My signs of dystocia
are: Temp just before labor readjusts back up
to normal; If I have no puppy born in four hours.
That is my definition of primary uterine inertia.
Straining hard for an hour... that is when you
would NOT give oxytocin. Longer than three hours
between puppies, that's when you DO give oxytocin.
Any black, red, or green discharge before any
puppies are delivered indicates placental detachment
and needs attention. Ultrasounds, fetal monitoring
devices, are critical to determine fetal well
being. The ability to monitor the fetal heart
rate is essential with WhelpWise or having an
ultrasound. I have worked and consulted with
breeders using WhelpWise; it's ESPECIALLY important
if a veterinarian does not have ultrasound,
because there is no other way to monitor the
whelps and fetal health
16. Question: What is
WhelpWise?
DrHutch:
WhelpWise is the sponsor of this event, actually...
it is a fetal monitoring service. You can monitor
your bitch's labor progression and fetal heart
beat at home. They work well with your veterinarian.
They are at www.whelpwise.com. Thank you Karen!
Karen Copely, the owner and founder of WhelpWise.
I believe that we have the right to expect every
puppy that our bitch carries; I am not one who
believes you get a litter because you expect
to throw one away. The ones we work the hardest
on, often turn out to be the best!
17. Question: Is there
any reason to suspect ultrasound causes reabsorption
of puppies?
DrHutch:
Ultrasounding is normally done day 26-28, when
the heart starts beating on the puppy, so we
can monitor viability as well as pregnancy.
Absorption can occur up until around day 37-38.
Now that we are ultrasounding, we are REALIZING
that absorption is not uncommon in the bitch,
but ultrasound is only diagnosing it, it's not
causing it. Just as x-raying a bitch at day
52 does NOT cause cataracts or whatever in the
bitch; it gives us a WHALE of a lot of information
about how many pups, their size, their positioning
, and their health. That is an urban legend.
Absorption is most commonly caused when the
uterus is not able to support the placenta and
give nutrition to the puppies; genetic problems
that stop the puppies from developing; there
can be some viral of infectious causes; there
have been some toxins identified in large animals
more so than in small animals. Trauma probably
plays no role, such as palpation or jumping
off the porch.
18. Question: Reliability
of progesterone testing? I have seen the progesterone
testing of a bitch to determine ideal breeding
times, to be off by as much as three days.....according
to my stud dog...and the successful breeding LATER
than the test suggested. Care to comment on this???
DrHutch:
It is best if one can obtain progesterone numbers,
which should not be a problem in this day and
age. Progesterone tests are not species specific,
so can be run in human labs, dog labs, horse
labs. The biggest mistake people make in running
progesterone tests is they stop before the progesterone
goes above five nanograms. The day the progesterone
goes above five nanograms is the day of ovulation.
The whole world revolves around five nanograms.
T The fact that we could determine just the
initial rise (rise to 2-3 nanograms of progesterone)
is a total fallacy. You must confirm ovulation.
I start testing around day 6 of the cycle. You
need to run your progesterone every 2-3 days.
19. Question: What is
the most reliable in house test?
DrHutch:
At this point, I recommend you find an outside
lab to give you a number, as opposed to running
in house tests; they are not as accurate.
20. Question: Doesn't
the time lag cause a problem?
DrHutch:
You should be able to get the results back in
24 hours max. If there IS a time lag problem,
check with a human hospital, or if nothing else,
overnight them to me! I can have them that same
afternoon!
21. Question: What about
the LH surge?
DrHutch:
Because the LH test has to be run every day,
and LH is species specific, and in most cases
even running the LH we still put most faith
in the progesterone tests, I do not run the
LH except in very, very specific cases. And
the bitches appreciate not being BLED every
day for 14 days in a row.... the urine LH is
not successful.
22. Question: What about
supplementing progesterone?
DrHutch:
The bitch's sole source of progesterone is the
ovary. She does not switch the source of progesterone
to the placenta like the horse or the cat, therefore
it is very uncommon for a bitch to lose a litter
due to a premature drop in progesterone. Giving
progesterone when it's not needed will cause
birth defects in the female puppies. If we need
to supplement progesterone, I use progesterone
in oil injections, as they do show up on progesterone
tests, which tells us when to give the next
dose. There is an oral synthetic progesterone
called Regumate which is used on horses. It
will not show up on progesterone tests and therefore
will not be monitored. We only need 2 and one
half nanograms of progesterone to maintain a
pregnancy. Most bitches during a pregnancy have
8-10 times that amount. A bitch dropping from
20 nanograms to 15 nanograms would still have
plenty, and you would definitely not supplement.
I only supplement if the bitch drops lower than
5 nanograms and we have longer than 7 days to
our anticipated due date The bitch's due date,
63 days from her ovulation date, the date she
went above 5 nanograms progesterone. Breeding
date has nothing to do with whelping date It's
the OVULATION date. So if you know the day your
bitch goes above 5 nanograms, you can set her
due date at 63 days from that as her whelping
date: set up your whelping box, take the day
off work.
23. Question: After
progesterone reaches 5 nanograms, what are the
best days for breeding?
DrHutch:
The bitch ovulates an immature egg that has
to mature for 48 hours before it can be fertilized.
The breeding depends on the anticpated life
of semen. A natural breeding can be done the
day of 5 nanograms, the day after... the life
of the semen is going to cover it. The fresh
cooled semen should be 48 hours after 5 nanograms.
Frozen, we breed 72 hours after 5 nanograms,
because frozen semen only lives 12 hours. Slightly
later is better than slightly early because
you want the egg to be ready to be fertilized.
24. Question: Dr. Hutchison,
are we intervening too much and harming our breeds
with all these AIs, surgical inseminations, etc?
DrHutch:
I don't believe that ignoring technicological
advances, advances our breeding. I believe anything
we can do to make breeding successful, like
using frozen semen... is good. Anything we can
do to improve our dog breeding and have more
live, healthy puppies, interventions in safe,
healthy manners, can only be a positive. I think
the Cornell study that showed you get more live
puppies from a c-section, showed us that intervention
can be a benefit by saving those normal puppies
who by some reason cannot get through the birthing
process. Being able to go back to breed to frozen
semen from a dog from 25 years ago can only
be a positive thing, bringing some of those
lost traits back into our lines Plus I need
to do this, I have a high maintanance wife.
~ ~ ~
There were so many great questions, but we
have just run out of time... we will have more
information in a follow up email... but I just
love you guys - you ask the best and the greatest
questions and I would like to get to each and
every one of them. So many exciting things lie
ahead for us dog breeders. Embryo transfer,
in-vitro fertilization, frozen ova to name a
few. Yet, I always am amazed at the number of
people, especially veterinarians, critical of
us for wanting to breed our bitches. They blame
us for the great pet over-population problems,
like breeding uncontrolled, mixed breeds is
our goal. Go forth, improve your breeds, and
good luck on your next litter, it may contain
the best one ever!! "Puppies are like veterinarians,
way too many, just not enough good ones!!"
Thank you, Thank you, Thank you!!! Good night
