i am not sure how different the symptoms of hind gut ulcers are from the symptoms of front end ulcers. Hind end ulcers cannot be seen by a scope. i guess if you have treated for front end ulcers with Gastrogard and are still seeing signs of ulcers, then try Succeed for the hind end ulcers. If you suspect any ulcers it is important that the horse have access to forage most of the day. Chew time is really impt for horses that have ulcers.
Magnisium deficiencies can manifest by changes in temperament.
If the most obvious sign of his fretting when he's on his own is pacing until he's fed, then that is easily remedied--more hay, small-hole nets, etc.
I can't give you any advice about hindgut ulcers, except that my impression is that gastric ulcers are a lot more straightforward. Or maybe I just understand them better, which is not to say that I'm any expert at all. But a 30 day course of ranitidine or omeprazole is a decent empirical trial that's unlikely to do harm and may take care of the problem from a "what's hurting" standpoint. But more forage (or making his forage last longer) is crucial to both types of ulcers, as I understand it, and so easy to remedy unless the horse is grossly obese.
I'm not sure corn is "bad" but anything with starch is hugely guilty of being the Evil Ingredient. Perhaps in many cases with good reason, but bits of corn in the feed is unlikely to make or break the average, healthy horse.
How about 24 hour turnout--an option?
Forage is what protects the top part of the stomach from acid. The bottom half has a thick mucous layer to protect it. Ulcers can affect either part of the stomach but forage and the quarts of saliva used to chew it are what really keep the stomach healthy.
A lot of people think Equishure is a great product--never tried it on any of mine, though.
If leaving ulcers alone is a "zero" and omeprazole is "ten", ranitidine is probably a "seven or eight". Before we had omeprazole, drugs in the ranitidine family were GAME CHANGERS in the treatment of ulcers. And you don't run the risk of causing rebound acid hypersecretion with ranitidine like you can get if high dose omeprazole is stopped abruptly.
Ranitidine has been around for about 10 years longer than omeprazole, BTW.
Ranitidine is a darn good drug, but ideally is dosed 3x daily. (if you're really doing an empirical trial without a firm diagnosis you want to maximize the chances of seeing response vs. no response) I'm lucky--my beasts will all eat the pop rocks and I only use them for shipping anyhow. But if I had to treat a horse on a budget I'd be very comfortable with ranitidine.
how much ranitidine do you feed and where do you get it?
If you're asking me, I don't feed it so I can't answer. But I've heard of people getting it at Costco, Sam's Club, and also online equine pharmacies. Hopefully you'll get more helpful answers than that! I think the dose is 6.5mg/kg or roughly 3000mg every 8 hours for a 1000 pound horse.
Costco does sell ranitidine without a prescription (you need one for the horse pills) but they are in 75 mg, so you have to feed a lot of pills. I would assume the horse pills are cheAper if your vet will write the prescription for you.
That's a great price! Valley Vet (just looked) has 250 x 300mg for $32 with free shipping. That would be about a week's worth for a big horse.
Pills vary depending on manufacture WRT being water soluble or soften-able. But a cheapo coffee grinder will do the trick.
Samotis, did you check the dose for sure? 12 tablets PER DOSE is what my math tells me, not 12 tablets per day. 12 tabs/day would only give you 1200 mg/dose or about 2.5mg/kg and I don't think that's the right dose.

What is the most important information I should know about Ranitidine:
Ranitidine is a non-prescription medication not FDA approved for veterinary use; however, it is a commonly accepted practice for veterinarians to use this medication in dogs and cats to reduce the amount of stomach acid produced. In addition, it is often used in the treatment of ulcers in horses. Ranitidine is available over the counter as packages containing 24 x 150mg tablets. The usual dose in dogs is 0.22mg to 0.44mg per pound every 8 to 12 hours. The usual dose in cats is 0.22mg per pound every 12 hours. The usual dose in horses is 5-10 mg /kg 2 to 4 times a day.
Best check with your vet, though--I haven't used the drug in horses.
I paid roughly $35 out the door at Costco for enough ranitidine to treat a horse with eleven 300-mg pills three times a day for three weeks. It does dissolve fairly well in water, at least if it's pre-ground. I suspect that it would dissolve OK even if not ground, but there is some sort of coating on the pills. We ground it and put it in applesauce (note - NOT cinnamon flavored!).
We scoped after the three weeks and the ulcers had gone from grade 2-3 to less than grade 1 (you could see a few tiny lesions). It was rather neat to watch, but I don't think it was much fun for poor Star who HATES having a nasogastric tube passed. Even though we'd fasted for the requisite time, he still had enough fluid in his stomach that she had to flush and pump it out. The vet then advised me to keep him on the ranitidine for another week and to give it to him for a couple of days any time he was in a stressful situation. She did say something to the effect that "now that you know ranitidine works on him" so I assume that means it doesn't work on every horse.
I think the more typical symptoms of hind gut ulcers that differ from stomach is that horses with hind gut ulcers tend to be bloated and gas colicky. They often show signs of discomfort after eating and often have diarrhea. The treatment used for my gelding was sucralfate, psyllium and a short fibre diet. He was taken off hay completely and eats soaked cubes and mashes. A blood test revealed his protein levels were really low and his stomach scope sowed no tummy ulcers. That's how we diagnosed my guy. To me your guy doesn't really sound like hind gut ulcers but I'm no vet . And tummy ulcers may be more expensive to treat, but simply giving GG once a day is a HECK of a lot easier than feeding a short fibre diet
