Lowline qualification question

I was looking at some cattle yesterday at one of my buddy's pastures and he had a pretty moderate angus heifer.  Not the itty bitty so called defect.  Just moderate.  If these were to be used with lowline genetics would they at most only be 1/2 blood lowlines if bred to a purebred Lowline bull?  I think that lowlines originated from an angus herd so I didn't know if there were exceptions for angus cattle in general.  I'm of the mindset that they would be 1/2 blood lowlines....I just don't know for sure. 

Yup, if they used a Fullblood (not purebred) Lowline bull, the claves would be registerable 1/2 Lowline.

I am sure a lowline breeder will jump in if I have this wrong but this is my take on the way lowlines came about. A research program in NSW in the late 70's took a herd of angus and bred the big ones to big and small ones to small. They ended up with some 80's type angus very tall and some 50's/60's type angus very small. A TV personality from a lifestyle program found the "lowline" herd just before it was due to be slaughtered as the research had finished bought the lot of a song and made a fortune by promoting them on his national program. From this a few cautionary notes form Australia. Many very good marketing people have been involved in the lowlines in Australia. The original herd was developed only by breeding small to small not for efficiency or carcase yield. The percentage registration system in the US should only help the breed

Lowline breeder jumping in here.  (lol)  Here is a link to a previous thread on SP about the history of Lowlines, http://www.steerplanet.com/bb/index.php?topic=938.0  It is true that the highlines and Lowlines were similar in feed efficiency, however the lowlines could be stocked at a higher rate on the same acreage which yielded more pounds of meat per acre which is still true today.  Here is a link to a chart showing average stocking rates and final yield per acre for various beef breeds based on the research from the Trangie research station, http://www.4rfarmslowlines.com/facts.php
