Can a horse get ulcers without being on grain. Just being on free range hay?
My point being, "yes" the horse on free range hay and not receiving grain can have ulcersBetween 60-90% of foals and stalled weanlings have ulcers.
As this poster stated U-gard can also be used to test... feed it for a while. It isn't a treatment it is used to prevent or to use after omeprazole treatment is completed.Ulcers are associated with stress - and we can put our horses through stress without even realizing it - I wonder how many foals get ulcers when they get weaned because that is a really stressful time for them.
Feeding grain and nothing else might cause ulcers because the horse would be standing without food for long periods of time but fed as a supplemental part of its diet with grazing or hay shouldn't be a problem at all
I have found that a supplement called U-Gard works really well and I add to my horses feeds if I think they are for any reason going through a stress period or if they have to be on pain meds that are likely to cause stomach irritation
What makes you think your horse has ulcers?
