This is where a necropsy/tox screen by a professional agency would be truly enlightening... feed? Pesticides? When I was looking into bulk feeds for our cattle, I was looking at mill run pellets, ($80 CAD/ton!) but the company said they wouldn’t sell to me if I had any pigs... due to “potential” ergot, and something else I can’t quite recall contamination. Wouldn’t affect the cattle or sheep, but can with porcines. I couldn’t make their minimum order of 28 tons though so it dead ended.
Maybe something like that?
