eating

Question
I wonder if corn stalks and all the plant parts can be eaten by pottbelly pig

Answer
Pigs enjoy corn. The can eat the leaves, husks, stalks and kernels. But, the cobs are not digestible and can cause a blockage, so don't let them have the empty cobs. The silk (those fine threadlike things at the top of the corn) is not digestible either, and the fine threads can get stuck in their teeth and cause problems.

So almost the whole plant can be eaten. Just not the empty cobs or the silks.
