Sorry you all had to go through this, but glad you learned a tricky new secret to keeping your herd safe.
I doubt many people know about this particular toxin and you'll be able to protect your animals from it easily now. :)
I just finished a 4-day fast and am amazed at the results it has had on me. I wonder if a sick animal should be left without food for a day or two to help it in the same way.
we don't let the sick ones have anything but water and hay, no grain or forage.
You know much much better than I do. It just struck me as a possible option. Sounds like you were doing something along those lines already.
