Pigs Can’t Eat Parsnips

Pigs should not be fed parsnips as they give them blisters in and around their mouths.

“Parsnip tops contains substances (furocoumarins) which , in contact with bare skin, enhance the skin’s sensitivity to the ultra violet rays in direct sunlight. The affected skin becomes red and inflamed and then develops blisters and extensive angry looking skin erosions.”  The pigsite.com

If anyone has any experience of parsnips giving pigs blisters then please leave a comment.
