I used to boil it, then ground , now I feed it whole. After reading several articles with different info, I figured whole is safe, as long as you don't soak it with the feed. I keep mine extra and dump it in the moist feed right before feeding. It's all about not " activating" the prussic acid too early, which happens when it comes in contact with water and then releases into the feed. Apparently horse's digestive juices take care of it when it is" fresh". Does that make sense lol? I feed 4oz, split into two meals,btw
Thanks Guys, it's very confusing as years ago when I fed it we used to boil it because it contains components of cyanide however soneone told me the other day that it could be fed if it was simply soaked without boiling (and also whole)
I usually feed whole and dry with my horse's regular grain ration.
For a little while I was feeding Triple Crown Omega Max (a ground stabilized flax seed) but my horse wasn't eating it as well as the whole. I inquired with Triple Crown if it was safe to soak it into a mash and was told that yes, it was safe. The amount of cyanide is so small, even if you're feeding 1 lb a day (which I don't) it's not enough to do any harm.
I wouldn't boil just because that destroys the omega-3 fatty acids, which is the primary reason I feed it to begin with.
