I have a pony with a sensitive system (I’ve posted more concerns about him in the past year than I have in all other years combined!).
He had bad ulcers, and per the vet’s advice he is still on a low-dose of omeprazole. He’s also on sucralfate (has been on since third week of April). He gets a small amount of grain. He’s out in pasture all night with access to grass. During the day he has enough coastal to last him the day. And he gets two flakes of alfalfa a day. He’s not a super easy keeper when it comes to weight and is probably slightly under ideal weight.
None of the above has changed recently, the sucralfate starting in April is the newest change.
The last couple weeks he has suddenly become very gassy. He has always been the type to pass manure while being ridden–small amounts more than once usually. But lately instead of passing small amounts of manure, he is passing lots gas. I wouldn’t worry about this too much, except that he becomes very uncomfortable before he passes gas. He will get behind my leg, fussy in the bridle, have trouble maintaining rhythm and go around with his tail up for several strides and then finally the gas will pass in a string of farts and he’ll be back to normal…until 10 minutes or so later when he needs to fart again. It’s the same on the lunge.
Given that nothing in particular has had a recent change, I’m not sure what the source of his farts are. I tried pulling his alfalfa for a few days to see if that made a difference–it didn’t. I removed the sucralfate for a few days–no difference. And I’ve pulled the omeprazole for a few days–no difference. I’ve thought about trying to keep him off grass for a day or so to see how that goes, but haven’t tried that yet. There’s no dry lot, so that would mean keeping him in overnight and my instinct says that a gasy horse should be moving, not stallbound. His temp is normal, his hydration seems good, and he is bright eyed and normal on the ground (he’s not farting around in his stall or in the pasture either from what I can see). So, I’m not sure what to make of this and would love additional horse-people brain power on what I should try.
He does not do well with probios or equisure/ritetrac (he’s had them in the past). I’ve thought about psyllium and worming (it’s been 3 months since his last fecal). But I don’t want to throw the kitchen sink at him all at once since he is sensitive.
Any thoughts on what might be making him so gassy?
