Some not all. Depends a little on what you are calling "sweet feed" too. Many pelleted feeds are actually sweet feeds... Purina makes some bottom of the barrel c.rap too... It really depends on what your horse needs. If your horse is doing ok on SC, then I'd probably stay with it (I'm not a huge Purina fan, but it depends on which Purina product). I would guess that if a horse is doing well on SC, they will do well on Purina or most any other feed. And MFTOwner, Safechoice does (or did) indeed change their ingredients. In all fairness, I stopped buying it years ago so I suppose it is possible they have switched to a fixed formula. But on another horse forum I belong to members were complaining about SafeChoice changing from an beet pulp base to an alfalfa base -- and this was fairly recent. ANd from another forum (last year): "Anyway we talked with the feed store owner and he talked with Nutrena. They changed an ingredient from Rice to Peanut. " Our local vet sent samples of many different feeds to be tested to see if they all met their GA. Safe Choice failed with flying colors. The various Purina feeds didn't do all that well either. If I recall, Blue Seal and Triple Crown did ok. Here's a link from this forum that has some Purina Strategy vs. SC info: http://myhorseforum.com/threads/139874/ As I said, I do have an issue with a company that tauts a feed as safe for ALL horses (even ones with metbolic issues) when that feed could actually hurt those horses.
