Lev 11:7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you.
The swine even though it be cloven-footed it does not chew the cud a pig is known for eating a lot more than just vegetation in a manner that is unclean, they will consume anything that you put in front of them.
This is what the Most High created them for, which is to clean the waste of the earth.
Lev 11:8 Of their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you.
The carcase of a dead pig is not even supposed to be touched because it is so toxic according to the scriptures, we must always bare that in mind.
