No, but not having anything to eat, at all, for 12 hours a day, every day, is a great recipe for ulcers.
I don’t subscribe to the “they must have something in front of them 24x7” mantra because that’s a man-made notion that isn’t rooted in how a horse works. On free range pasture, horses only eat 16/18 hours a day. they spend time walking and napping and sleeping and playing, and never, ever ever eat 24x7.
The number of times a horse is fed is not how to evaluate things - there’s context missing. I only feed once a day in Summer, twice a day in Winter. But they always have forage available. But they still aren’t eating 24x7, even in Summer when they’re out on pasture with good grass. In Winter, I put hay out twice a day, but each time it’s enough to give them access to hay until I put more out.
If a horse goes 2 hours a day, every day, without forage, that’s typically not a recipe for ulcers. 1 hours, 8 times a day, also not a recipe. What matters most is how many hours at a time, on a regular basis, they are not allowed to eat anything at all.
12 hours a day, every day, is a terrible way to keep a horse.
Some horses can be kept this way ^^^ from the day they were foaled and never have ulcers and then another horse can be kept with hay 24/7 and have ulcers. I know this from personal experience in a long time boarding situation.
I challenge anyone to show that a horse without anything to eat for 12 hours a day, every day, doesn’t have ulcers
I do agree that most horses would be happy to eat whenever they choose, but sometimes due to weight or boarding situations it is not possible.
I agree that many boarding situations don’t offer as much hay as really necessary. Sometimes, that’s acceptable. What’s described is not.
