Apologies ahead for the long post. I have a 26 year old gelding that is struggling with FFWS or something similar. Historically he has had a sensitive stomach and predictably gets loose poop for a couple days when hay changes or there are stressors like a new horse moving into his pasture.
Had some issues with fecal water over the summer as clover popped up strong. He has a history of finding things to eat in the pasture that don’t agree with his stomach. At a previous boarding facility every fall he would eat acorns that fell into his pasture and get terrible diarrhea. The last 2 years that I’ve been at this boarding facility I haven’t had any trouble with him eating weird things in the fall and there is not much for him to pick at in his pasture now so I don’t think that is likely the problem this time.
About two weeks ahead of the vet visit a 1st cut round bale was put out and he was able to slowly start to nibble at it but mostly searching for grass still. I can’t remember what day his herd was closed off from most of their pasture but I believe it was shortly after the vet was here. They still had some grass in their dry lot/paddock area but nowhere near as much.
10/7/2024 - fall vet visit, blood drawn for CBC, Lyme, and ACTH testing done, began Firocoxib (generic Equioxx)
10/21/2024 - Prascend arrived and began to get him to half a tab per day for a while and reassess given his symptoms and levels were only slightly above the allowed seasonal rise, he had the tiniest bit of fecal water but figured it was from grass running out and the change to eating more hay
10/26/2024 - last day giving Firocoxib, fecal water became terrible over the last week, trial without to see if it improves, poop has been normal but liquid before and after pooping
10/29/2024 - finished the first round bale and had a 2nd cut round bale go out, a bit of loose poop for 2 days after the new bale went out which is typical for him as bales are switched
11/5/2024 - started ProElite GutBiome supplement, the hay switch or stopping of Firocoxib has left his butt a bit less crusty but there are still streaks down his leg and liquid along with his well formed poop
11/10/2024 - adding 1 tsp salt to his feed
He’s at a boarding facility so I don’t have control over hay but the barn owners were very willing to try the other cutting of round bales from a different supplier that they have to see if that would make a difference. This change seemed promising but only a slight decrease in amount of liquid down his backside.
Current diet:
24/7 access to grass round bale in pasture, don’t know what type of grass.
AM: 1.1 lbs Triple Crown Senior Gold, 0.5 lb Triple Crown Balancer, SmartComfort
PM: 0.5 lbs Triple Crown Senior Gold, 0.5 lb Triple Crown Balancer, 1.5 lbs alfalfa pellets, ProElite GutBiome, and 1 tsp salt wet with approx. 4 cups water
I’d like to put him back on the Firocoxib because I noticed a big difference in his comfort, especially with the cooler weather, but am nervous about doing that until he’s better and I can test whether the Firocoxib makes it much worse or not. Hoping I won’t have to put the poor guy through standing outside to get his butt hosed off with cold water when it’s way below freezing.
I’ve got a message in to his vet but in the meantime I’m hoping to get some ideas for what to try next or opinions on the most likely culprit for his FFWS issues?
