Did you take your pig to the vet. His poor skin looks more like a lice infection than some thing he ate. Look deep in his ears to see if there is any movement. They may look like dried skin flakes.

Yes thanks for your concern. piggy is being seen by a vet. that is why he is convinced its a phototoxicity issue. No lice. we worm regularily.

In my research and requests i've found a few of the weeds and what they are. But still have a few more unidentified. if anyone can help it would be much appreciated.

Thanks!

Please note that we "human animals" can be affected by these plants, too! In particular, buckwheat greens (i.e., the plant tops, as distinguished from the seeds, which are not phototoxic) are sometimes used as a salad green, in green smoothies, or for juicing, and St. Johnswort is a medicinal herb used to alleviate depression.

I am in the process of healing from the effects of including buckwheat greens in my daily diet. I'll post a link to a really good article that tells what it's like.

Sorry I don't recognize any of your mystery plants.
