[QUOTE="OK Jeanne, post: 244123, member: 3333"] There was no "selection criteria" that I know of.....they only included breeds that had over 100 animals tested. The only hair samples used were those sent in by the owners of the subject animals....the company did not pick out animals to test. The procedure was simply the test to see if they had those dna factors or not. The tests themselves were validated by the shear force test on slaughtered animals. I can't think of any other way actually to validate the test procedure; it's not like grade, i.e. a subjective measurement of intramuscular fat. I would think that shear force is the only objective way to measure tenderness. I don't believe every animal with a perfect tenderness score would inevitably be tender. There are other factors that influence ultimate tenderness---but I do think that the genetic propensity for tenderness is a good goal for anyone wanting to produce quality beef. [/QUOTE]
