Progress
in Importation Permits
NOW
frozen semen is sent to CANADA by FedEx with NO PERMIT PROBLEMS.
Germany is a wonderfully easy country to send frozen semen...a tank leaves
our facility on Monday and arrives in Germany on Wednesday. Norway, Sweden,
and Holland are still a little tricky and England is "do-able"
but not without some hair-raising discussions with officials. Australia
sends a different import permit every time. The latest permit on my desk,
requires the dog owner abstain from breeding their stud between collections
and requires the semen shipped in a new tank or suitably disinfected tank.
Other Australian permits recently sent to us have no mention of these
requirements.
Our own government has blessed us by providing vets graduating from the University of California at Davis with federal accreditation status without taking a test. However, if your vet graduated in another state and moved to California to practice, he/she MAY NOT be listed on the federally accredited list.
Years ago, whole days were devoted to taking tanks to airports to properly document and seal the tanks and get them onto the proper overseas fights. Because frozen semen was sent in liquid nitrogen tanks, the shipping tanks were considered hazardous goods and additional hazardous goods documents were required. Some shipping companies have been miserably ill prepared to handle frozen semen shipments. In our experience, the shipping has never resulted in a loss, but Customs in Australia once lost sperm: they didn't empty all the frozen semen out of the shipping tank and didn't notice their mistake until the dog owners wanted to use their sperm. Another Australian disaster: the vet didn't charge his storage tank, resulting in lost sperm. In England, the University veterinarian who was to do the insemination was at a conference when the bitch was ready and his technician did the inseminations. No pups resulted. When the bitch cycled into her next season the bitch owner notified the University but the remaining semen could not be found.
Success
Requires
Strict Attention to Detail
Dealing
with the regulations of international shipping and customs, duties and
agriculture departments can be very unnerving. However, when the pups
whelp, all the problems are forgotten. After all, international breedings
are celebratory in that these breeding combinations may become the savior
of genetic diversity for several breeds. Rare breeds will now have access
to individuals all over the world!
Important
Tips in Dealing
with Foreign Semen Importers
When
contacted by foreign breeders to provide frozen semen, remember to ask
for import permit details before agreeing on stud fees, etc. You may be
very inconvenienced getting appointments for collections, various vet
certificates and laboratory tests, so I always suggest adding on a nonrefundable
fee to compensate you for your time. If you are concerned about which
bitch will be inseminated, make certain of your understanding of the country's
Kennel Club rules. I used to urge clients to send a whole collection to
Australia, because if the bitch missed (which is very possible!), she
could be rebred the next time. If she conceived the first time and then
conceived a second time or if by agreement with the American owner, the
remaining semen was used and produced a litter with another bitch, the
American stud owner would be entitled to stud fees for each litter. This
arrangement seemed very fair and showed good faith on the side of our
American breeders. Indeed, some American owners were happy with the "annuity"
arrangement. However, the Australian Kennel Club changed their rules and
now allows the importing party to own the sperm and sell it to anyone
without notifying the American stud owner. Litters resulting from those
frozen semen breedings are registerable. SO BEWARE!
One Great Dane breeder was thrilled to be asked for frozen semen by an Australian veterinarian, but was concerned because the vet didn't know into which bitch it would be inseminated. In fact, he didn't admit owning any Great Danes. For some breeders this arrangement may be suitable but please, be an informed, aware, stud owner when evaluating foreign semen importers.
Carol's Note: This semen storage was on the verge of being discarded by the owner a couple of years ago. Fortunately, it was saved and put to good use, still in the same excellent condition as when it was collected! |
Freezing viable sperm from your dog today may just become be the single most important investment you make for the future of your chosen breed.
HOW DOES IT WORK?
Collection
Collection
of the semen is done by appointment. A copy of AKC registration and an
AKC DNA certificate number is needed (DNA sampling may be done here).
Most dogs provide the best collections when teased by an estrous bitch.
To assure quality collections, breeders usually schedule collections to
coincide with a bitch's heat cycle or one that is arranged by the Canine
Cryobank.
Processing
Immediately
after collection the semen is analyzed under the microscope. At this time,
it can be determined if the collection is worthy of preserving based on
the sperm count, volume, and motility.
A cryoprotectant, often called an extender, is then added to protect the cells from ice crystal formation when frozen. The semen/cryoprotectant mixture is cooled 2 to 3 hours, and mixed gently and continuously. At intervals, more extender is added. The extended semen is then dispensed into 1/2 CC straws, labeled indelibly with the dog's identification code and frozen in liquid nitrogen.
Storage
The
straws are placed into labeled plastic goblets. The breeding units are
stored in liquid nitrogen tanks at minus 196 degrees Centigrade. At this
low temperature all molecular activity is halted and the cells (in a state
of suspended animation) can be preserved for many years without loss of
fertility.
Liquid storage
tanks do not depend on electricity to maintain the required temperature.
There is an annual storage fee charged to maintain the breeding units.

These two borzois are from frozen semen over ten years stored. They are two of six frozen pups produced by Kumasan's Hunyak of Tradition, owned by world renown animal communicator, Lydia Hiby (lydiahiby.com) of California. |
