Mm. Cyanide is poison. Period. The amount it takes to kill a
critter depends on the size and digestive system of the critter.
Maybe the cows died because they have a double digestive system,
thereby roughly doubling the amount of cyanide in their system
compared to what the horses would have.
There is cyanide in the seeds of various fruits (apples, at least)
But in order to be poisoned by appleseeds a person has to actually
cut open the seed and ingest a great many of them - otherwise the
shell keeps you from digesting it and it passes through. Isn't it
almonds that eventually "rot" so that they contain too much cyanide
to be healthy? cyanide gas supposedly smells like almonds.

Cyanide (CN) can combine w/ other elements. I don't remember enough
of my chemistry to remember how easily it does so naturally.
