We run some beef cattle here, and used to take one to the butcher shop now and then, but recently my wife prefers to buy from the grocery store only the "cuts" of beef she/we like. For a while we had three freezers running and sucking lots of electricity, and each one had packages of UFOs (Unidentified Objects) near the bottom. Things like tongue, tripe, oxtails, livers, hearts, etc. After building my ground mount solar arrays, I gave away the chest freezer to save energy. Now the two remaining freezers are so full there isn't even room for a Pita Bread!
On the day after election day, my neighbor was in a bad mood. One of his bull calves had escaped again, and would not cooperate in getting back behind the fences, so the neighbor shot the animal. He "field dressed" it on the spot, and offered us a hind quarter.
Here is a photo of some of it BBQing in my copy of a Whitlox wood forge. It was tasty, but tough as Jerky, so we ate some, and cut the rest up into small pieces and made it into Goulash in our slow cooker. Also makes good Chili. If you haul an animal to the butcher shop, they hang it to age and that makes it somewhat tender. Old cows are usually converted into Steakburgers. I remember seeing speciality butcher shops in France that sold Horsemeat. For a while, excess horses from Texas were exported to Mexico for slaughter, but I believe the treehuggers and animal rights activists have put an end to that.
