Keeping lost does genes

[Hudson River Rabbitry]

I am just beginning to breed Silver Fox and recently and suddenly lost my only doe of breeding age. She was a beauty and a great loss. However, before passing, she gave me a beautiful litter of five (2 bucks and 3 doe). One of the bucks as a Jr. bumped to a 6/8 won Best 6/8 Buck, Best Fur and BOB at the 2009 PASRBA show. His siblings also did very well.
Here's my question;
Is it OK to breed siblings of gen II just one time? This would produce gen III. Then, I could breed a buck from gen III back to it's dam of gen II, thereby producing gen IV. If my understanding is correct, gen IV genes would be 3/4 that of the lost doe.
If this is correct, is it advisable?
Thanks

How closely related were the parents of this litter?

So sorry you lost the doe.:tears2:

They were not related at all.

Its kind of close is there any way of borrowing the father of your doe from a breeder to use to your gen II?
Pamnock would be the best at answering this but I think it makes your line awfully close. If it was me and I had to do that then I would look for an outcross (same bloodline but not kept by you ) for 3rd generation if that makes sense

I'm of the opinion that inbreeding is fine for a generation or two. You clearly have a very good reason to do this pairing and as long as you're careful who you allow to go on for breeding I don't see much harm in it.

This is just my personal take, of course.

Hey Dani,
Thanks for your comment. It's kinda what I was thinking. It would be a one time thing.
Are you guys going to the Fulton show?

Hey Gerry.

I'm trying to talk the husband into attending the Fulton Show. Our local club is sanctioning SF for a show that Sunday too so it may be a big weekend for us.

Rabbits can handle quite a bit of inbreeding, there was a study done(which I'm trying to find a copy of) where they bred full siblings for 18 generations before starting to see problems. My Silvers have numerous full sibling crosses behind them, and I've been doing sire daughter crosses because I can't find an unrelated fawn buck. Fawns are the rarest Silver color, and as its frowned on to cross the colors its very hard to find new blood. My Silvers are hail and hearty, no fertility, temperament, or health problems. All of them are just tightly linebred enough to be their own granpa. Happens with rare breeds, hard not to have to breed tightly.

Well, hope to see you there! And good luck at your home show.

That's interesting and somewhat reassuring. I think I'm gonna try it once and see what happens.
Thanks!
