This, or the best option (IMO) would be to PREVENT them by ensuring management is optimal for preventing ulcers: forage available at all times (hay or grass), limit stress, and using a proven preventative during times of stress (trailering, moving barns, showing,etc), and making sure if the horse is eating grain, that it’s a grain that isn’t conducive to ulcers (like a high starch feed).[/QUOTE]
I agree with this advice plus I would feed some alfalfa – hay, cubes or pellets. Alfalfa helps buffer stomach acid and it is has been shown to both prevent ulcers and help them heal. I believe the study was done by the U of Texas.
My own OTTB gets alfalfa pellets as part of his ration, free choice hay and 24/7 turnout.
I personally wouldn’t buy an extra supplement to prevent ulcers if a horse doesn’t have them when this is something that can be managed by feed.
