LostInReverie -- the "reply with quote" function isn't working, so I'm excerpting part of what you note above:
At the same time, I don't think breeding Satins necessarily means breeding more with this disease. I don't know much about breeding, or genetics, but I was told once in reference to breeding dogs that you don't get good genes from bad stock. In other words, the correct way to breed healthy Satins would be to find some without osteodystrophy. If it's possible to test pigs to see whether or not they have and/or carry osteodystrophy, that is.
You bring up something that has been on my mind, which is repeated by so-called "responsible" breeders -- the possibility of testing, tracking, appropriately logging, and sharing the data for genetic traits in a certain breeding pool. I'm not saying that you are arguing this is the right thing -- you've helpfully brought it up and I'd like to bring out the point.
As someone who has a family (immediate and extended) with multiple genetic challenges, I know what researchers go through to try to locate, isolate, test for / remediate etc human genetic "flaws." I'm talking about FraXa, trisomy, and number of congenital issues. Well-trained, well-funded researchers have enormous databases with comparatively large sums of money (compared to, say, a cavy breeder -- they are underfunded in human terms). And yet there is no "cure" or "fix" for these genetic issues despite decades of research.
I try to get my mind around an animal breeder trying to tell me that they are so competent and technically advanced that they can track things like the gene that carries the Satin/osteodystrophy trait, specifically breed it out, with reliable charts, databases, funding and so forth. I cannot picture any breeder of cavies, dogs, etc. that has a system that approaches what they have at the NIH or major research universities, and yet they allege that they can figure out a way to fix this and end up with the Perfect Satin (or other animal).
And in time alone -- with the hit-or-miss type of breeding, you'd have to be back-breeding your pigs to end up with any kind of remediation in a reasonable amount of time. But then the people who say they are "responsible" breeders say that they don't back-breed. So what are we talking about, then? Being willing to wait 15 years to create one perfect Satin with zero genetic flaws (again, assuming this is even possible)? Who is going to buy your $250,000 pig?
Advocates for "responsible" breeding don't make any sense. THere is no internal logic to what they are saying, when it comes to vanity breeding like building the perfect Satin. And there is no justification for bringing into the world the "rejects" just because someone wants a piece of living jewelry.
Again, I'm just building on Lost in Reverie's point -- I am not at all saying that Lost in Reverie is saying that breeding Satins is okay! :*)
