How is it you know the circumstances behind the lady who bought the carrier mare? ----- --- Just answer me one question before you go off on another tirade about evil "BIG BREEDERS" and SCID....can this affliction be 100 percent controlled? The answer is obvious. You just won't admit it.
You have a completely different point of view, which is your choice, as a breeder. Obviously, you are more of a "risk" taker, in losing foals, losing sales or breedings.
I, & many like me, choose to NOT lose any foals or reproduce SCIDs Carriers. Foals are hard enough to get from conception to maturity, without having to worry about KNOWN genetic diseases.
Why should anyone be penalized for believing that a "testable genetic disease", should be bred away from ? I don't want to see any of the other Arabian genetic problems, as listed earlier, either, if I can help it, do you ?
SCIDs is not associated with BODY type, as in the case of HYPP, in Quarter Horses. There is no SIGNIFICANT BENEFIT to having a SCIDs Carrier Stallion standing at stud.
Our Vet went to Cornell U.(NY), and his "class" did SCIDs research, way back when. They were driving to many Arabian breeding farms to collect samples. He has seen the effects of breeding Carrier to Carrier and the AFFECTED foals that are "lost". He definitely has opinions about it, & he also suggests SCIDs testing for Pre -Purchase exams for breeding stock. Do you remember that question a Vet is supposed to ask at the Pre Purchase exam ? "WHAT IS THE INTENDED USE OF THE HORSE YOU ARE LOOKING TO BUY ?"
I do not want to have to sort my foal crops by Carrier/ Non Carrier. I firmly believe the "breeding stock" corral with Non Carriers will be sold out long before the Carrier group.
I counseled this lady, in particular, personally, about SCIDs, and SHE made an INFORMED decision. I have no idea what other specific stallions she was looking to breed to, either, and yes, it is a "BUYER BEWARE" market. "Too Bad" for her, for not asking about SCIDs testing of the sire or dam, or the mare she was purchasing.
Hysterical ? At the time, she was devastated, since she had "dreams" and that was not one of them. Is she now Informed? YES!
The BIG BREEDER knew they had CARRIER mares & stallions and chose to take the chance that:
a) a "newbie" would not even know about SCIDs,
a potential "buyer" would never think of it as a "pre purchase exam" requirement, or would the VET ask about testing ?,
c) they lose one every now and then--so what, who would know?
d) they figure they would lose breedings to their stallion if they tell, so they test privately, and don't tell...
e) figure they will be out of business in a few years, anyway.
If testing WERE required at the time of DNA sampling, and put on registration papers, people would make more informed decisions, and eventually there would be less SCIDs. Don't you think ?
Has there been a request to the registry about adding SCIDs testing as a foal registration requirement ? I would think there would be "Labs" that would put in competitive bids for the work to keep costs down so our fees would not be too high. DNA testing today is much easier and cheaper to do than blood typing, so perhaps the technology is better with SCIDs testing as well, for a cheaper cost.
I just happen to want a SCIDs free herd, and know that any one of the other "maladies" can happen too.
Our Vet says that if you are in it long enough, you will see it all.
I also re-read the book of foaling complications each Spring.
I count everyone I KNOW who is having foals on my list of 100, since 95% of equine births are normal. I hope I don't have all 5 of the others.
We had twins 2 days in a row a couple of years ago, with only 1 foal surviving. Both mares were checked in foal using ultrasound. What are the odds of having twins in that case, and then, what are the odds of having another mare (TB x TB) having twins the next day?
You can get odds on everything.
We had 11 colts before having a filly. One mare had 4 colts before having a filly, another had 4 colts for us and no fillies. The Vet kept saying, "It is 50/50 every time". Same odds as SCIDs Carrier odds.
Let me now ask you a question, Roger.
If you stand a stallion at stud, and tell me he is not tested for SCIDs, would you test him if I wanted to breed to him ?
