Re: Dwarf breeder - Isle of Man?

I breed short to short in the US, and I get 0% deformed aborted "bulldogs". How is that possible? It's because many "shorts" don't have the chondrodysplasia gene... there are all sorts of other genes that can make Dexters "short". In my herd, I have eliminated the chond...

Re: bringing back the extinct dexter

I've bred hundreds of red Dexters that trace back to Irish Red Dexters in the 1890's. No living Dexters have pedigrees tracing 100% completely back to Ireland with no holes. All Dexters have some holes in their distant pedigrees. If you think you have a Dexter with no holes in their distant pedigree...

Re: bringing back the extinct dexter

This is a silly article. The red gene is already in thousands of US Dexter's. I've had hundreds of them.

Re: Harley Poll - 1894 Foundation Dexter

In 2011, the likelihood that the poll gene is hiding in Dexters with stunted horn growths was discussed here in this forum. But that was before testing was available, and it was before we discovered the likelihood that there have always been some Dexters with the polled gene, since the foundation. N...

Re: Harley Poll - 1894 Foundation Dexter

The Dexters pictured above with horn growths, that also have a hidden polled gene, are not my animals. The animals are tested as having a poll gene, and are registered as polled by the registries. I'm trying to get copies of all their polled tests. I do have one so far. Here it is. https://i.ibb.co/...

Re: Harley Poll - 1894 Foundation Dexter

Concerning Godstone Esmeralda, nearly all of us had false information about Dexters in the past, so we were forced to invent possible answers to explain her polledness. Here is the false information that made us question Esmeralda's pedigree: Myth: The original 1890 Irish Dexter Breed Standard requi...

Re: Harley Poll - 1894 Foundation Dexter

Of the many of thousands of Dexters in history prior to the 1980's, there are no records of horn status for any of them because horn status wasn't tracked. We have to assume that each one of those thousands of historic Dexters has an “UNKNOWN” horn status until we have some degree of evidence one wa...

Re: Harley Poll - 1894 Foundation Dexter

My information has nothing to do with being a "Devil's Advocate" . I have a ton of genetics expertise and information analysis expertise and I have researched this very carefully. Facts: 1. The 1890 Royal Dublin Society Dexter Herdbook volume 1, discussed five old Irish breeds of cattle in...

Re: Harley Poll - 1894 Foundation Dexter

This is a picture of a purebred registered Dexter bull. He is tested and registered as having a hidden polled gene, and he has scur-horns. The polled gene can hide in animals with horns and can hide especially well in de-horned herds.

Re: Weighing Calves

I take a very thick piece of plywood board perhaps 2 feet by 2 feet square, out to the pasture, along with a bathroom scale. I lay the plywood on a flat area of the pasture near the newborn calf, and place the scale on the plywood. I weigh myself 2 or 3 times to make certain the scale is stable and ...

Re: Photo of Chondrodysplastic Steer Joint

I did some research on osteochondrosis/osteochondritis. I found that it can be triggered by mutant ACAN (aggrecan) genes. Aggrecan is an important component of healthy cartilage. So it turns out that broken ACAN genes which are the cause of chondrodysplasia in Dexters, can also be the cause of osteo...

Interested in comments regarding this photo, especially from Louisa Gidney 1. This is the joint of a two year old Chondrodysplastic steer with arthritic joints. 2. The other joints were also deformed and arthritic. 3. This steer was born on the breeder's farm to a chondro-Dexter mother. 4. This stee...
