Does anyone know if ADGA has a problem with registering kids from 2 reg. animals who are Full siblings?What is the worse that could be born from this OOPS breeding,both animals are very correct,ect.Thanks

Yes ADGA will register tem, there is no problem with that. The worst that will happen with this breeding is that the kid will be smaller, less vigorous, (for example a buck may be less interested in breeding), and have all the faults of it's parents to an extreme degree. If both parents have a slight degree of turned out feet, the kid's feet may turn out even worse, not any worse however, than they would from two unrelated parents that both had the trait. On the bright side, if both parents are really great, you could get something even better in the kid. With inbreeding, you will be concentrating the genes. Whatever is there already, will be intensified. You won't get three headed kids with overshot jaws unless those genes are already present in the parents.

With line breeding or inbreeding, as Rebekah said, it will act to concentrate what's already there - good and bad. You can get a massive increase in quality (good or bad) this way, but you have to be prepared to cull heavily to get the good result. Short term (just a few generations) it can be a good thing to do.

Yes, as rebekah and don said they will register them. I belive this is what is referred to as "Line breeding" if it works and as "In breeding" if it doesn't. this is actually one of the ways to test your genetics, although it is usually father to daughter or grandfather to dam. This way you will get either the best of the line or see the faults. many of my American Alpine lines are heavily inter related. Good luck.

"I belive this is what is referred to as "Line breeding" if it works and as "In breeding" if it doesn't." This response is incorrect. According to Ensmingers Animal Science, Inbreeding is the mating of animals more closely related than the average of the population from which they came. Line breeding is the mating of animals more distantly related than in closebreeding and in which the matings are usually directed toward keeping the offspring closely related to some highly admired ancestor; such as half-brother to half-sister, female to grandsire and cousins.

Dearest Dave,

While your correction of the correct definations of the terms are appreciated, the terminology used by many breeders is basically summed up in my usage of the definations. I shall not split hairs here regarding the definations. This terminology is used amongst many goat breeders to describe their breedings. I belive I shall pass on the correct definations as per your post to the many goat lists I subscribe to for clarification.

-- Bernice (geminigoats@yahoo.com), December 04, 2001.

What I have read is that when the two animals being mated produce an offspring that is no more than 50% of a particular animal, linebreeding is being done. If I breed a Sasin son to a Sasin daughter and the dams are unrelated, we have linebreeding, even though they are half brother and sister.

If the relationship in the offspring is greater than 50%, we have inbreeding, which can also be useful. If the Sasin daughter was bred back to Sasin, the offspring will be 75% Sasin, that's inbreeding. A lot of people call inbreeding, anything that would not be acceptable in human relations. This isn't so with animals.

There is some truth in what Bernice says. Regardless of the technical definitions, people who are admired or liked are said, approvingly, to be conducting a great linebreeding program. When people who are disliked for whatever reason (maybe they are competition?!) do the same type of breeding, it is disparaged as inbreeding, thus undermining that person's reputation.

Bernice is correct. It is a breers way using "slang" I guess. But in horses I can tell you they do use the "line breeding if it works, inbreeding if it don't" phrase.
