I was planning to possibly keep a doeling out of Cupcake. Now I can't, of course, so I'm debating keeping one out of Panzy. I would have the breeding option of breeding her to her father, or to her half brother (mother's son). Is either of those ever an okay plan? Out of the two options, is one better than the other?

According to this article, it seems that the next most risky "group" to be avoided, would be: uncle to niece, aunt to nephew, half siblings & first cousins! Those, I believe I will stay away from! Sounds like anything else would be pretty safe as long as it is not repeated again, thereby multiplying the animals (and the genes) over again in the pedigree.
So in this scenario below, if I bred "millie" to Calvin, he would be her grandfather, and 1/4 of her genetics, right? And this would be line breeding because I'm not breeding "millie's" mom "calvetta" back to calvin? (which would be parent/sibling breeding)

Deb, are you saying that if I bred say, Ginger, one of my unrelated does to say, Calvin. Then she has a doe. We'll call that doe Calvetta. Then I bred Calvetta to Milton, and she had a doe. We'll call that one Millie. Are you saying I could breed Millie to Calvin?
I'll have to try that, I guess! In the break down Margaret shared, the guy basically said that anything that isn't parent to offspring or sibling to sibling would be considered line breeding. That made the most sense to me so far... if that's true. lol

OK girls, I haven't read all this yet, ( sorry got lots going on right now) but it looks like it might be decent: http://davidcavill.wordpress.com/a-beginners-guide-to-inbreeding-an... Later guys!
How's this ... look at a pedigree, and just put a great grandfather's name on there twice. That's line breeding! :)

That's a great idea! I love it, really. This is a great conversation. It's complicated, but I'm learning. :)

You shouldn't get anything fatal with linebreeding like that, so I say go for it. You never know until you try. I've linebred on a doe that was a national champion and was really disappointed in the milk production of the resulting does, but then that great grandma was never on 305-day test, so she may not have been a great producer, even though she had a beautiful udder. That's one of the reasons I want to start using my own homegrown bucks. I know the does intimately -- teat length, orifices, personality, production, you name it -- and I have several generations in some cases, so hopefully fewer surprises. ND breeders were into showing a lot more than milking early on, so I'm afraid there are quite a few gorgeous udders out there that don't have the production that I want.
This all confuses me so badly. I'm such a visual learner, and I just can't PICTURE what line breeding looks like. lol
The majority of my crossing will be done by taking does that are buck 1's (Foops great grandson) and breeding them back to buck 2 (Foops great great grandson). And then the reverse of that, does from buck 2 bred back to buck 1. Does that sound safe enough?
I have 5 does with one buck and 4 with the other buck and any retained does from any of those breedings will get bred back to the other buck!
Since I also have 3 sets of half sisters, with each set sharing a father but no shared moms, I also made sure that I split the sisters up so that 1 of each set is bred to each buck. I figured by doing this I may get a little better idea which of the genetic mixes would produce the best results! Of course, I realize doing only one breeding won't tell me to much, but I figure if I swap the girls next time and some of the same matches (genetically speaking) give me the same results then I will have a better idea as to if I am actually on to something with those breedings. If all goes as expected, after that second breeding, I should be able to tell by then exactly which buck is doing what for my production & conformation plus which of the pairings are actually producing the best results!
You could do this, or you could the linebreeding in your previous example. I'm doing both.
