Re: [AlpacaTalk] CA
Yes, here's another post of mine that people may be having trouble with. I'll bold the important words, other than that the text is the same as the original post on the group.
Laurel,The last cria was born to this dam last year. I have no idea if she's been bred again. I've only met this person a couple of times and really only know this story because I was told by the sire owner. And apparently this breeder has had quite a bit of bad luck. He has some females with certain sires in their pedigrees twice, which he attributes to some of his bad luck. His dam with the 3 CA crias had different lines than his "linebred" females. By the way, I only know this much from searching ARI.The first case I spoke about, the sire in question has almost 50 registered offspring in 3 years of breeding and is owned by numerous partners. He is still being promoted and I'm sure breedings are being sold. I'm sure that number will increase by at least a dozen when the '09 crias are registered. Will all of those owners be told that the sire has thrown a CA cria? How many has he produced? I doubt that it will ever be disclosed.I was told by another breeder that she had a sire, we'll call Joe, with a particular import sire in his background, and 2 breedings with 2 different dams were disastrous. I don't know the name of her sire, she didn't tell me. She did not specify what those disastrous results were, and honestly, I can't really say that the import sire should be held responsible. I don't even know that the import sire was Joe's sire, could have been grandsire or great grandsire. What about the other animals in Joe's lineage? Joe's dam might have had the bad genes, not the import sire.So you see, this is not so easy to tell people "Your really should cull any animal that has had a relative with CA." Who knows where it came from, in the lineage?HeatherOn Jun 25, 2009, at 1:02 PM, Bluebird Hills Farm wrote:Heather,
I find it hard to believe that the only defect Formula 409 would cause is choanal atresia. Are there other alpacas drinking out of the same bucket? Have they all had CA crias? I think what is seen here is a dam that throws CA and that in her case it is a dominant defect. There have been llamas that have done similarly. Terrible bad and sad luck for the owners.
The best that could be done with this situation is necropsies of the cria although it is probably too late. Blood samples of all sires and the dam sent to Andy Merriwether.
Quick search (very quick) did not show any birth defects secondary to Formula 409, but it was very quick.
