I think we are heading to some major changes in meat.
My father was in the large scale side of cattle breeding. When he started, the breeds were called "handyman" sizes, and the Herefords and Angus were dumpy little inefficient things, with dwarfism issues.
Rural land was very cheap, so they bred for carcass quality, but also size to lower cost. (The Feds we're pushing the handy man thing, and had some design for a slaughterhouse to make them profitable, but it was an insanely expensive design - the gov't presenter had not even worked out construction costs when he presented the slaughterhouse design.)
The biggest take away fromGabe Brown, especially in an era of expensive rural land, is reworking for profit per acre.
There will be a balance point there between carcass size, and how much meat is produced per acre.
