Phototoxic?

You have SUN in Midlothian?

Shouldn't think there will be anything to worry about this year!

This may have been meant to be a bit tongue-in-cheek but
there seems to be a bit more to it than just sunlight. It
seems to have caused a goat some trouble in this case:

"Suspected poisoning of a goat by giant hogweed

AH Andrews, CJ Giles, and LR Thomsett

A five-year-old male African pygmy goat became ill four
weeks after transfer from a zoological garden to a municipal
park. The animal was subdued, refused to eat and drink and
showed profuse salivation. Examination of the mouth revealed
severe ulceration. The condition gradually responded to
nursing and supportive therapy. Circumstantial evidence
suggested the possibility that the lesions were caused by
giant hogweed (Heracleum mantegazzianum). Supportive
evidence that the plant could produce lesions was provided
by the application of a cut stem to the hard palate and a
solution of various dilutions to clipped areas of the backs
of two ewes. Both ewes produced reddened skin when the
concentrated solution was applied and both showed marked
reddening of the gingival mucosae and in one animal small
ulcers developed in the rostral part of the mouth. It is
suggested that H mantegazzianum may be a potential hazard
for grazing ruminants."

I have always been under the impression that goats could eat
pretty much anything. I did come across other info
suggesting that hogs and cows could be used to help keep
Giant Hogweed in check. I wouldn't think that there would be
that much difference between the three animals but it seems
like there is or this hasn't been thoroughly researched
(shrug).
