Most cattle today are probably going to be in some sort of fence. Wild cattle make for good television, but are much harder to find in real life.
I would think twice before pulling the trigger on any "wild cattle", as you may face fines or imprisonment when the cattle-owner/ cowboy shows up, and you're butchering his Bessie that escaped confinement.
Escapees from confinement or "lost" cattle are probably more routine, especially in fence-out states, vs. fence-in states. if i were going to kill a "wild cow" here in FL, I would use modern archery equipment to muffle the shot.
immigrants that pass thru this area do this more regrettably more routinely than needed, and use a chainsaw to butcher in a hurry, often times making a run with the hide still attached before discovery.
the beef industry is really doing well here in FL, with the drought significantly affecting beef prices throughout TX, & USA.
