Looking for a medium sized butcher/meatpacker who does a bunch of beef around the DFW area (preferably an Ag) there's a possible business opportunity I want to look at. Not looking for box-to-box distributors.

Sorry, not to familiar with the meat processing world, not good with animals (except when cooking or eating them ).

Are you looking for processors who take it in on the hoof? The closest to Dallas that I know of is the Kaufman Meat Locker, which looks like it has changed owners: https://noble-meat.com/

The butcher that I use is Huse's in Malone. https://www.husescountrymeats.com/

There's The Meat Board in Fort Worth, it's own by a group of Aggies.

Is the Hico area too far? If not check out Hartness Cattle.
