actually GB the Herefords eliminated it but I believe the other breed and the association associated with it took the ostrich approach that is still prevalent today - call the AAA and ask them about Fawn Calf Syndrome - there have been breeding trials in Australia - the breeding traces to US genetics - and I can't get them to be interested in a potential case here in the US - in fact they have ignored it since Nov!! While you are at it ask them about the Long Nosed Dwarf and why testing for it has to go thru the AAA lab (despite the fact that the test was developed elsewhere??) ---isn't that like the fox guarding the hen house??? And remember the old snorter dwarf was not eliminated in the Herefords overnight - just like it didn't appear overnight - As I delve into other defects in other breeds I am actually more impressed with both the AMAA and the ASA - were they perfect - he** NO! but by comparison --- and I agree that they were just more open - perhaps the internet forced this openness (remember there was no internet at the turn of the century
hereford breeders revolted at a national convention as those in power wanted to keep all records of carriers quiet. story is in a book titled battle of the bull runts or something similar. got a copy for christmas. it took about 30 years for enough ladies in waiting to accrue, and as linebreeding kinda went out of favor with the dispersal of gudgell and simpson, though one breeder after them still practiced it a lot. i think the comment in the book alluding that the angus had it as well was kind of a slight.
by the way, check out this website in progress!!!!!!!!!!!!! he wrote the basics of linebreeding. too much of the book details the founding of jewish ancestry versus the same example in herefords, but you get the point about concentrating genetics can have power if you cull. when you don't cull, and or test cross, you get in trouble.

amazing the prices paid back then and the rapid "progress" made.
another book talks about herefords and performance cattle called courageous cattleman and there's one story in there about comprest cattle and some pretty amazing breeders.
