do pigs walk on their metatarsals or metacarpals?

Answer 1

Both are used in walking. The metacarpals are in the forelimbs, and the metatarsals are in the hind limbs.

However, if you are talking about what bones come into closest contact with the ground, they are the digits or phalanges in both the forelimbs and the hind limbs.

You might have been caught in a "decision trap." See this article:

I hope this helps. Thanks for asking.
