...I couoldn't find anything really clarifying the way "bloodlines" are being treated or defined in GTP's. Lots of great info on GTP husbandry and husbandry history, I especially liked the locality discussions, but not really anything as far as bloodline.
The second link was interesting and had nice pictures. Is that considered a record/documentation for bloodline purposes? I still need to get a better idea of how the bloodlines are handled to be able to compare them to other methods but I am still definitely interested. My only concern, if the pictoral clutch record is considered documentation, is that it seems no more informative then taking someones word that a particular specimen is from pure stock.
I agree with your word usage analogy. Basically I am treating "pure breed" as a ideal/goal and you are treating it more as a criteria for inclusion. And yes I agree we are basically looking at the same thing as well.
Two other points though. "Pure breed" does not in itself imply inbreeding. The key distinction is whether the registery is closed book or not. If the registery has a means for new WC specimens to be entered in then it should have no more impact on inbreeding then keeping breeding record do. However if they have completely closed books, as the AKC does, then i does in general lean towards inbreeding. This is because the gene pool is locked and even if it is large enough to in general avoid the "inbreeding" issue it is still structurally encouraging/favoring inbreeding.
Secondly I completely agree with the detrimental effects of inbreeding in many of the "pure"breed dogs. That being said the inbreeding is not, from my personal experience with papered dogs and shows, caused by the papering or emphasis on "pure" breeds. The real culprit in purebred dog inbreeding is the emphasis on line breeding for those traits that will cause the dog to win awards at the show and thereby become more valuable stud/dam. This is actually the source of my distrust, at the gut level, of the term boodlines since that is the term commonly used in canines when they are being inbred for show purposes.
The perfect example of the dog show judges prefferences directing inbreeding/linebreeding to detrimental effect is german sheperds in the US. They used to be great work dogs but nowadays are unfit. The emphasis in the shows was for GS's to have shorter hindlegs causing them to have a angled squating appearance even when they were standing up. This continued to cause the back legs to be bred shorter and now hip/back problems are issues where they weren't before and the specimens are not suited to certain physical activities the way they were before. Not to mention any side effects of the inbreeding for the small legs. I have not looked up what effects have become more prevalent as a result but the common ones in canines are premature blindness, premature deafness, organ problems, and emotional/tempermental issues.
This is also why some of the best(quality not show success) german shepard breeders go to the effort to import breeding stock from out of country.
If you know where there is some more explicit explanation of the GTP bloodline system then I'd be very interested in reading up on it. Thanks for the links and info.
Sean.
