Young male born 10/8/2015 still with only one testicle. Wanting to steer this animal. Unsure of how long to wait. Vet will be doing procedure. Anyone else encounter this in Dexters?

Yes, we had done a special breeding to the Dexter bull, Hillview Dynamo SP5, ADCA No. 10815, which resulted in a bull calf, Wakarusa HD Dudley, and Dudley had only one testicle descended (we waited 6 months for the second testicle to descend, but it never did). We steered Dudley (the testicle in the scrotum was removed by the vet), but the internal testicle was left and he developed like a bull and acted like a bull. We kept him with our bulls (in a separate field) and then with our steers in a separate pasture. He was processed at 2 years of age.
Another registered Dexter bull that had only one testicle descended was Quailgate Arthur, ADCA No. 016868, and he was related to Hillview Dynamo SP5. As far as I know, Hillview Dynamo SP5 did not have this issue.

Anything more current Patti? That article is dated 1992.
It also states "Polled Hereford and Shorthorn cattle were at significantly greater risk for cryptorchidism; however", "polled cattle were not at an increased risk for cryptorchidism".
Hopefully they weeded out most of the cryptorchidism in those breeds by now.

There is a small article about "Testicular Deformities" on Gabriella Nancis website. I would post it here but I would need her permission.

legendrockranch, we can post a link to her website, though. Almost any blogger/website appreciates links. Here's a LINK to Gabriella Nanci's article on testicular deformitites.

Thanks for bringing this topic to the discussion board, poplinfarmdexter. This is a defect that has apparently occurred in several Dexter bulls (not just your bull calf), and breeders need to pay attention to this issue.

Thanks Susan, I guess what was interesting to me about the article was that it said the "same defective gene will cause deformities in the internal reproductive organs of female relatives".

Aha!!!! I now have electricity, rather than relying on the generator a couple of times a day. Know whaat that means? bad news: I'm BA-ACK.
There used to be a lot of discussion about Woodmagic Beaver II being cryptorchid. I know of one breeder who had a lot of woodmagic-based animals, and over time he did have one bull calf with a single testicle. cheers, c.

Woodmagic Beaver II was born 11-18-1977, and his offspring started arriving in the Cranworth herd in March 1980. He was imported into Canada in 1979 by Doris Crowe (Cranworth Herd), an experienced Dexter owner/breeder. Since he would have been around 18-months old when he bred his first cows in her herd, it would have been quite obvious if he was a cryptorchid. It would have been obvious to Beryl Rutherford (Woodmagic Herd), another very experienced breeder, when he was being evaluated as a herd sire prospect to represent her herd in Canada. So I guess that what I'm saying is that the possibility of that type of defect going undetected by two experienced Dexter breeders on this bull would have been nil to none. Here are his ADCA registered offspring: www.dextercattle.org/pedigreedb/ponyweb.cgi?search&ParentID=2399&Sort=6

From what I have read on the subject the inheritance of cryptorchidism is far from simple and it is not easy to completely avoid as even those bulls which have never left a cryptorchid calf could well be carrying it. The obvious thing we can all do as breeders is never to breed from a cryptorchid bull. I castrate a lot of bull calves of a lot of other breeds and it does crop up now and then but the incidence is always very low, even when a large crop of calves are off the same bull. There are also occasional calves with what I call "short cords" where one testicle is descended but only just, sometimes in the scrotum but sometimes under the skin in front of it. These are almost certainly caused by the same genetics but just expressed to a different degree.
There are lots of genetic faults with incomplete inheritance which we should probably be aware of but in practice are very difficult to control. Another one is "wry tail". I have seen a number of calves labelled as such which had nothing at all wrong, a number where the tail was a little to one side, and the extreme is the tail permanently bent to one side, probably with other bends along its length. The anus is never covered in these cases, and some even exhibit gait abnormalities with a tendency to "hop" rather than trot. Investigations have shown this to be of complicated heritability too.
We need to be wary of branding individuals or herds without good reason, and we need to avoid unsubstantiated historical blame, which often, as has been suggested, casts serious doubt on the reputation of deceased breeders of great note.

Patti, Doris knew zero, zip about Dexters when she started and not a lot more when she stopped. Marshall was with the Foreign Service, the Crowes followed the 'thing' of the day and bought themselves a 100 acre farm in a poor section of the Canadian Shield with lots of rock and water, in fact they had an island in the River they used as a summer place to get away friom the heat, outside Ottawa as a weekend place to go. Their friends the Higgins, also important in the federal Cdn gov't, bought another farm about 1/2 mile down the road. They started out with Angus but couldn't make enough to cover the farm status. They spent over $70,000 IN THE LATE '70S! to upgrade the old brick farmhouse and driveway, but didn't have running water in the barn, or stalls. (Try that in the winter with temps in the minus degrees--hoses were used and then laid out downhill to drain until the next time.) Doris wouldn't have known a monorchid from a haystack at the beginning. They only kept Beaver a short time and sold him on to Highfield Stock Faarm in Alberta. Doris didn't understand about dwarfism either, and bought a dwarf bull she liked better from a US breeder (Highland Perseus) along with some cows from the Klein herd, and was advertising her animals as non-dwarf even though all the US ones were. They also made another trip to England to find a new bull but told the Kleins that they didn't see anything they liked as well as the one the Kleins had had and they wished they'd bought him when they had the chance (Direct from the Kleins about 20 years ago) When the Cdn assn was staarted, no upgrading was allowed, but Doris was upgrading anyway and registering in England to get around the problem, whilst at the same time was a Director of the new assn. They had a paid helper who ran the farm for them on a day-to-day basis. One of those was Eric Lawlor, a university student at the Agricultural college in Ontario. He is the one with the knowledge, and it was from him I learned about the monorchidism. Eric also went to England to help Beryl, and the Crowes paid for Beryl to come to Canada. Beryl was appalled when she saw the dwarf bull they used to replace Beaver, and...there were words.
I don't mind your proclivity to whitewsh, but I know you like to get your facts straight, so here's your chance.
cheers, c.

c. Well, Doris Crowe replaced Highland Perseus with Woodmagic Beaver II, not vice-versa. Here is a record of her registrations, with dates, showing which bull sired the calves registered from her herd, each year. I doubt that she would have kept and used a son of Woodmagic Beaver II (i.e. Trillium Cluny) if Woodmagic Beaver II had been a cryptorchid. She used Woodmagic Beaver II for several breeding seasons: www.dextercattle.org/pedigreedb/ponyweb.cgi?search&BreederName=Doris%20Crowe&Page=1&Sort=6I checked both the CLRC record and the ADCA record and Highland Perseus only has 4 registered offspring in either registry.
