Interesting, I sell mature cows in good shape to my daughter for burger cows for their shop. I usually buy the loins back for steak. Just finished one of the best Rib eye I have ever ate. Works good for me as I get steak without all the rest of the cuts. We also keep the briskets for smoking they get great burger which their customers are noticing how good they are.
A year or so back, a friend and i were lucky enough to have a neighbor rancher give us and old cow. We put it down, and butchered it. Turned everything to hamburger. Had all 225 lbs flash froze in 2 lb packages. Gave it all to family members and it ended up in British Columbia, Alberta, Saskatchewan and Manitoba.and Montana. All recipients were glad to get free burger, and ALL commented on the good beef they got. Old beef is GOOD :cowboy:
Corriente roping steers on grass or fed up are tasty too. Of course, they used to be about 4 years old before they got to the USA. Tails were long, feet were big, horns were big, now, not as old when they get here.
