I used it for a number of years. It is rather cheap and a good source for the omega's. The best is Menhaden fish meal. My buddy drove long distance some years ago and he would bring back the fish oil in five gallon buckets for like $30 and I think the meal was in 5 or 10 pound packs. I like the meal a little better because it was easier to just sprinkle it on the feed rather than dealing with the oils. I believe it was coming out of the northern part of the east coast but I am not quite sure. It was a number of years ago. It is a good natural source of the omega's and fatty acids. EWO
