SwaY Posted February 8, 2011 Share Posted February 8, 2011 Libendane Litter of 10 using 21year old frozen semen. A GEELONG vet clinic has used dog sperm frozen for more than 20 years to produce 10 great dane puppies. Bellarine Veterinary Practice Dr David Hopkins said Ballarat client Deidre McRae had frozen and stored sperm from one of her prized great danes, Liebendane Armstrong, in 1989. Twenty-one years later, long after that dog's death, his sperm has been used to spawn these new pups. The puppies, now eight weeks old, are all happy and healthy. Dr Hopkins said while breeding dogs using frozen sperm was not new technology, it was remarkable that semen frozen for so long could produce such a large, healthy litter. Ms McRae yesterday said she was "over the moon" with the results. "I was hoping for one or even two, but to have 10 is just unbelievable," she said. Dr Hopkins said the technology was most commonly used to breed professional sniffer dogs for Australian Customs. Ms McRae said she would keep some of the pups as show dogs, and would sell others. http://www.heraldsun.com.au/news/victoria/...x-1226001959430 http://www.geelongadvertiser.com.au/articl...41241_news.html Link to comment Share on other sites More sharing options...

Rottsup Posted February 8, 2011 Share Posted February 8, 2011 What an amazing accomplishment for the Vet who did the AI. Obviously great storage of the semen too for an overall success. Thanks for sharing this story Sway - very interesting. Link to comment Share on other sites More sharing options...
angelsun Posted February 8, 2011 Share Posted February 8, 2011 What people need to remember is that when semen is frozen, any degradation stops right there. Storage becomes the issue and as long as it remains in the correct container and temperature, there really is no difference between the same quality/motility of twenty year semen as there would be with semen a year old.

scrappynsuzie Posted February 8, 2011 Share Posted February 8, 2011 that is just fantastic. I'm just wondering how the "Type" of danes has changed over the 21 years since the sperm was frozen. The sire was a ch then, would he still be good enough now, and how will these puppies stack up against "modern" puppies. I am not being critical just wondering, as I know that some breeds are different now from twenty years ago. Link to comment Share on other sites More sharing options...
puglvr Posted February 8, 2011 Share Posted February 8, 2011 I hope I have the same/similar success with my fresh AI they did about 3 weeks ago. Fingers Crossed I'm waiting to get my boy's sperm frozen and they need half a day set aside just to do it. Link to comment Share on other sites More sharing options...

becks Posted February 8, 2011 Share Posted February 8, 2011 This is the dog I mentioned. Litter of 9 from 28 year old sperm From the Camrose retriever website CH.CAMROSE CABUS CHRISTOPHER (41 c.c.s)(Ch.Camrose Tallyrand of Anbria x Cabus Boltby Charmer.) Still 2nd top sire of all time,all breeds, in UK. Known as“Toffer” to his friends, Christopher was from an outcross mating of Ch. Camrose Tallyrand of Anbria to Cabus Botlby Charmer, and bred by Mrs. Zilpha Morgan (formerly Moriarty). However both his parents were from line-bred lines, and I believe this helped him be such a pre-potent sire. He was from a litter of 9, and I chose him because he favoured my Camrose line more than any of the others . He was no oil painting as a puppy ! Until he was over 6 months old, he was cow-hocked, and had a terrible front, and the most enormous woolly coat I have ever seen ! Fortunately, everything fell into place, and on his first outing at 7 months old, he was Best Puppy at a Championship show. After that he took his Junior Warrant 3 times over,, won his first c.c. at 2 and was made up at 3. However, it was not until he was 7 years old that he started to hit the high spots, and during that year he won Best in Show and several Gundog Groups, and took his last Group at the age of 9 (just a few months before he died). His total of 41 c.c.s was only beaten by one by his double grandson , Ch.Styal Scott of Glengilde, but his 2 Best in Shows is a record still in the breed. He also won 4 Res. Best in Shows and 8 Groups all at Ch. .Shows. His record as a sire still stands today, with a total of 27 Champions in U.K., and a total of 66 Worldwide. He pioneered the use of Frozen A.I. in dogs, and his semen has been stored for 30 years, and he has created another record by producing a litter of 9 pups 28 years after his death.

angelsun Posted February 8, 2011 Share Posted February 8, 2011 Whilst that is true, there is new techniques now that were not available back then hence the whole "wow" factor. In actual fact, very little has changed from when the ability to freeze successfully sperm came to being. Two main methods are used, both with good success over the years. The suspension liquids have changed slightly but still remain mostly the same as used THIRTY years ago. One method freezes slowly, the other in less than 3 seconds. What we have seen as a HUGE improvement is the ability to read with great accuracy, progesterone levels and therefore ensure a better chance of having a successful litter. Frozen is hinged on perfect timing, and 12 hours can make the difference between puppies and a miss. We have also seen huge advancements in the ability to protect chilled semen and keep it viable for many days compared to 12 hours in the beginning, to an average of 36 which is pretty normal, and now up to 14 days, making overseas shipping of chilled a reality, where a mere 5 years ago, it couldn't happen due to time constraints. I've been involved on one level or another of the frozen semen issue for many many years, and was fortunate to learn a lot of information from the head of ICSB who has been working in frozen for almost fifty years now, and made major headway when bringing back almost extinct species due to his work.

whippets Posted February 9, 2011 Share Posted February 9, 2011 I had almost the same discussion in regards to techniques when I spoke with Dr Watts (a repo specialist). He said that the technique really hasn't changed at all over the years. The main thing is the post thaw quality of the semen and the timing of the bitch.

Roishana Posted March 3, 2011 Share Posted March 3, 2011 We had semen taken in the early 90s , which was excellent quality, but they used the wrong extender when freezing. It is basically useless, and it is only sentamentaility as to why I am still storing it. We got one miracel pup 8 years ago, so I sitll have hopes. So not all semen will be viable. The semen from Camrose Cabus Christopher was amongst the very first taken, and produced the second AI litter ever (frist was Calahorra Afghans from memory), but the first using vaginal (non-suricical) insemination. Hope Phillipson of Ferngold bred the litter. This was the mid 70s. The semen has also been used several times here in Australia by Goldtreve Kennels (beryl and Fred Hession) of th eintervening yesrs. It is an amazing story. Harry spira was involved, but the work with dog semen at the Vet Faculty, Uni of Sydney followed years of work on cattle semen.
