Throw in the changing wants of consumers and packers, thousands of different environmental conditions, tens of thousands of producers all with varying management skills and all kinds of other variables. I have to wonder how much ego would you have to have to think you are smart enough write a computer program that would account for and compensate for each variable properly to breed better Herefords. And that is if the bovine genome is completely mapped and understood with no variation between breeds. At this point it is a pipe dream by people wanting to breed cattle without getting manure on their boots. But it sure is neat to put on pep rallies around the country to pump our composites and have a slick breed publication for a bunch of juniors and parents who will never see a Hereford again once they get their scholarship money.
