I sure don't think they were scanning for carcass quality in 1970 folks. If they were and I do not recall that, I have a very good reason, I was born in 1979. If they were indeed scanning cattle in 1970, our progress in the last 40 years has been lousy to say the least.
Aaron, The technology was developed in the early 60's. Here is the opening paragraph from an article by W.P. Garrigus in the 1963 Shorthorn World herd bull edition. "The use of ultrasonics for evaluating meatiness in live animals is passing out of the research phase and becoming a useful tool for alert, far-sighted breeders who wish to make a real contribution to breed improvement, and, at the same time, want to outdistance their competition."
Oldhorn is to be applauded as he evidently had the foresight to use this technology. For the most part, Shorthorn breeders ignored it. (He((, we even to banned AI for a long time!) It was adopted by a large number of Angus breeders. As they say..."The rest is history"!
Oldhorn, I want to thank you for sharing your insights and hope we hear more from you.
