I want to say first off, that I have not asked the neighbor about this bull, it is possible that it was a semen mixup or something along those lines but there is a problem in the Angus breed as big or bigger than ours. Like Clint stated, I know my brother has bought REGISTERED ANGUS bulls that ON THE PAPERS show to be full blood brothers (ET just different flushes)to bulls in AI studs that have sired horned calves out of his horned cows.
A second reason that I wanted to post this was to however show where "they" (Angus) do a slightly better job than us Hereford breeders. They do have and "enforce" a "breed standard". Even though this calf may be the product of registered parents he would not be registered as Angus must be all black with the possible exception of minimal white on the underside BEHIND the navel. In the Hereford breed we used to (sort of) self police. Any real "off types" would be discarded by the breeder. Now days it is ANYTHING GOES. In fact the bigger the goggle eyes, with no white on crest and no white on legs with total red hooves is almost CELEBRATED as ideal and even PROMOTED.

That reminds me of a story that was always told as the truth in Oklahoma although I really do not know if it was fact. One of the foundation Angus breeders of the state was asked " Do you think there is really some Holestein in today's Angus Cattle?" To which he supposedly replied: "If there isn't there should be."
