I'm sorting out which goats I can send to which of my friends bucks.What are the rules, what's ok and what's not.
From things I've read don't put brothers on sisters, sons on Mum's, dad's on daughters but otherwise anything goes!

When the results are good it is line breeding and when bad it is inbreeding.
The idea is to know what faults are in the lines and try not to breed too close to them. So if you know a goat had a slightly out of true mouth do not put it with another, further down the line, that you know is also from a goat with a slightly wonky mouth as you are doubling up the chances of "fixing" wonky mouths in your goats.
If a goat has an exceptionally good udder and no glaring faults then I would breed closer to "fix" the good udder trait.
You stand the chance of hidden genetic traits coming out but as long as you are prepared to cull anything that inherits really bad stuff then breed as you wish.
I have often gone back to grandfather if he throws what you require.

So a buck on his half-aunties is ok.Their Dad is his grand-dad, his mum is their half-sister.The bucks I've used till now are all champion angoras so not really any obvious faults.

We used to breed small mammals as a business , I had to learn a lot about genetics and breeding . Being small mammals we had a short gestation period so over six or more generations we could see the effect of in breeding to a degree.
It might not show in their appearance or bone structure but it can show as early deaths , arthritic joints mental problems , stress , and a whole host of things.
It's good to bring in a totally unrelated by at least seven lines billy once in a while to revitalize the cross breed vigour as line breading and close relative breeding tends to weaken the strain over several generations without it initially being recognised . When you have a business where the problems show suddenly you've lost it .

A couple of the big angora breeders have recently organised importing South African embryos to revamp the national herd. The bucks are selling for thousands, way out of my league.Some of my does will be visiting a friend's buck, just trying to learn what's a allowed and what's not.

Thank you, (I think - I'll reread that several times at a more awake time of day)
Why would it be ok to breed full siblings and not half siblings?

My understanding from that link was half siblings is fine, what is not ok is father to daughter where they are also half siblings. ie any female from breeding son back to mother. So you wouldn't put the Male back to his sister daughter haha sounds a little disturbing!

AA to CC =ACfull siblings AC to AC = AA, AC, CA or CC
AA to DD =ADso half siblings AC to AD = AA, AD, CA or CD more diverse than full siblings.
-
Doesn't make much sense to me that half siblings is a no-no and full siblings is ok but it's a totally academic question anyway as I wouldn't ever put any kind siblings together.I'm not trying to rescue an endangered breed or create a herd from one male.
Thank you for an interesting article but not really the info I need.
I'm trying to work out which of my friends champion bucks can breed with my does and if I can save some stud fees by using my own buck kid on a couple of them.

Brian plummers book are quite good at explaining line breeding simply. He is on about dogs but the principal is the same
