Read my post (#7) above. Skowronek is unlikely to have been a carrier.
I understand your thoughts about not wanting to test and seeing your money better spent purchasing hay - we all have to weigh up the risks and decide for ourselves. However, the ONLY way to prove ANY herd or individual is clear of SCID is to test.
I don't agree with your logic about the mutation being rampant just because the suspected lines were so heavily used. The straight Crabbet group is just as inbred as the SEs and it's not rampant there. The Davenports are known to carry SCID, and they are the most inbred of the lot, yet if you do an internet search you will only find ONE listed carrier. Moniet El Nefous is heavily used in SE breeding yet LFS is not rampant. Genes work on a "chance" basis only.
After certain people on the other forum said any SE horse testing as a carrier can't
be SE, how many SE breeders do you think would own up to having a carrier or breeding an affected foal? The German stallion Shams Sirius was tested as a carrier but thanks to the peer pressure within the SE breeding community they gelded him. Even the man who alerted the forum to the name of the horse was given a hard time.
Finally, even if all of these rumours about pedigree switches or non-Asil breeding were true - why would you not then assume that such switches/mistakes could have happened at ANY time? Whether or not you believe it is only a problem with the "Enno group" of horses, the fact is those horses and Shams Sirius are accepted by the PS as SEs. They are part of the genepool.
Think about it. Alot of money has been made by perpetuating the myth that the SE is magically clear of SCID just because they are Asil. How many SE foals dying from immune deficiency related illnesses have had SCID ruled out as a possibility, via testing? Very few I imagine, because the myth has been repeated so often. People will do and say anything for money. Call me cynical if you like!
The only guarantee of a SCID clear Arabian is a piece of paper from VetGen that says as much.
"The Kazmeen, Bint Riyala and Bint Risalla are know know to produce carriers"
Upon what do you base this statement? These are such common lines with the two mare's progeny crossed upon each other over and over that SCIDS were be very common when it is not.
Again, Has ANYONE with an SE EVER had a positive test?
The Skowronek line was used extensively in Egypt and the posibility that some of the progeny were sold to others as asil is quite possible.
