https://en.wikipedia.org/wiki/Cattle_feeding says that 9% of beef is raised by grazing.
Poultry is going to be almost all feed. Along with Pork.
Those are the 3 biggest sources of meat by far.
Most meat animals (or at least goats, sheep, and cows) worldwide feed on whatever grows on the ground (whether that be turnips, grass, or something else).
