The Ulc-R-Aid seems to be working on my Arab with stomach ulcers. He has finally put some weight back on.
It will also help if you get your horse off grain - maybe it is off grain and you're just saying that because it's the common word for anything going into the feed pan?
At any rate, nothing with grain in it - too hard on the digestive system.
Being in a boarding situation always makes these things tough unless the BO treats all the horses better than their children
If you've posted about this before I am sorry I don't remember what you're feeding your horse and what you have access to.
Can you get McCauley's or EquiPride?
McCauley's M-10 Balancer is grain-free and soy-free, as is EquiPride.
McCauley's average amt to feed is 1 - 2 lbs daily whereas EquiPride is a flat ten ounces daily.
EquiPride is very expensive but that still comes out to about 75 cents per day; the horse gets 5 ounces AM and PM. Some like the taste others do not, it could be mixed with timothy pellets for an easy keeper or rice bran for a hard keeper.
If it turns out you can't get this horse's ulcers to settle - I have one of my hard keepers on rice bran and a liquid vitamin that only takes one ounce. He's been on that diet for a month and the difference in him is jaw-dropping in a good way.
Soon as my other ulcer horse finishes up the TC Senior, his little Arab self is going on the same "liquid" diet but he will need pre-probiotics added. The other horse already gets "Succeed" for his hind gut ulcers which is a pre-biotic on steroids
Let us know how this all turns out
