Sheep eat phlaris grass! It was known as sleepy grass as they would often fall over after eating it Smile
Phalaris grass
sometimes causes a condition known as staggers (amongst other things) and its cause is still contested. One particular symptom of phalaris staggers is paralysis of the hind legs and can progress to fatal convulsions. Research into staggers led to the discovery of tryptamines in these grasses (thanks, sheep!) Interestingly, histological analysis of deceased sheep's brains following cases of phalaris staggers showed bluish striations... This perhaps ties in with what

Chimp Z said:
Science has also shown us that many causes of livestock death or "staggers" are from high amounts of cobalt build up in soil or other issues like mixing toxic legumes into their diet.
so, in the fatal, convulsive cases at least, tryptamines may have little to do with phalaris staggers at all. (Perhaps it should be mentioned, cobalt compounds often have a blue colour.)
However,
Sleepy grass -
Stipa robusta - is in an entirely different genus and contains LSA and related prenyltryptophan-derived alkaloids as its major active components, which are produced by an endophytic fungus (IIRC off the top of my head,
Epichloë sp. - I could well be wrong here). Jim de Korne mentioned this grass in the lysergamide chapter of his book,
Psychedelic Shamanism, whereas
Phalaris had its own chapter.
Then there is Lolium staggers (or something like that) which is caused by an entirely different group of (non-indolic) alkaloids sometimes found in
Lolium species.
Just to set things straight
There is still enormous scope for expanding our understanding of alkaloid occurrence in the Poaceae family. I do wonder whether anyone has examined the tryptamine content of the substrate species favoured by
Psilocybe semilanceata (attempting to veer back on topic - oh, hang on we're in the fly agaric thread. Whatever :roll: ).
We can conclude that most animals enjoy getting into altered states now and again.
Cows always eat liberty caps, where sheep avoid them
Most animals, except sheep :lol:
