Maybe. There is still an incredible amount that we don't know about prion diseases. So much, in fact, that there is continuing speculation that our original idea that scrapie was a viral disease may be correct after all. Something changes the three-dimensional shape of proteins in the central nervous system, and a virus is still as valid a possibility as a prion. By the way, most of what we know about BSE went out the window with the case in Texas that involved a cow that had no connection to meat meal from the U.K. That sent everybody back to the drawing board. As far as dadpad's comment on expense goes, cloning will never be as cheap as AI. The question is how exact you want the level of herd genetics to be.
