SEC-
You are right. 6807 was the "progenitor" of the excellent cattle which have been produced from these matings, and most of the son's of 6807 have a more desirable phenotype (and, consequently, genotype {EPD's} also) than 6807 himself. This is a prime and absolute example of why linebreeding works - and at the same time - must be CAREFULLY monitored and managed. It is not a game of tiddley-winks that we are playing here.
The beautiful catalogs, the breath-taking Ranches and Farms and the stimulating and exciting Auctions with the hypnotic Auctioneer's chants all blend together to encourage and motivate cattle sales - and that is all well and good - but the breeder's who actually do the work involved in the industry MUST be educated and knowledgeable in what they are doing, and KNOW when to breed X to Y, and when to say enough is enough. If one get's so caught up in one pattern of breeding that negative results occur, THAT is "throwing out the baby with the bath water!"
N BAR EMULATION EXT is a result of 1/2 sibling matings (EXT's sire AND dam were sired by the same bull - Emulation 31), and that is why EXT was such a remarkable Genetic influence on the Angus Breed - BUT - the negative lack of 'docility' (wild-eyed idiots!) which transpired with too close inbreeding ALSO came from Emulation 31 and his genetics. I saw Ankony collect Emulation 31 when they were at the Bennett, CO. breeding facility, (25+ years ago) and that crazy %#$%(*&^ was a potential killer! Like Begets Like - both good and bad. You have to know what you are doing! And even then you can screw up!
Thank you ALL for your participation on this thread. I appreciate it!
