They are high in Omega 6, which can cause inflammation. I think the max dose is 1 cup per day, so a bag lasts a really long time. The horses really liked them, but I didn't see any difference in their coats; I fed them for about a year.  I think there are safer ways to get oils into your horse that are high in Omega 3s with smaller amounts of 6s, so I can't say I'd feed them again. JMO.
