Apologies, this will likely get very long! I’m also going to post in multiple forums!

Early in February, my mare broke her pedal bone. About a week later she started going off her food, and long story short was found to be suffering from a caecal impaction, Right Dorsal Colitis (ie inflamed/ulcerated colon), and gastric ulcers – probably a reaction to the Danilon. She spent a month in horsepital, had 6 weeks worth of gastroguard for the gastric ulcers, IV fluids and the impaction cleared fairly well. The colitis was tougher – she was on sucralfate for a while, but the vets said there is little that they can do medically as it’s hard to get a drug to act as far into the digestive system. So google research led me to put her on a no-hay diet. Since late March she has been on 6 sloppy feeds a day/night of alternating soaked high fibre cubes and soaked grass nuts. Breakfast and dinner was chaff, unmollased sugar beet and topspec balancer. She’s on cosequin for the foot, plus has been on liquid coligone in her feed twice a day. She gets pink powder (4 scoops a day). I have been getting up at 3am every night for nearly 3 months to try to keep her on a regular feeding schedule. Technically she has been on box rest, but as she kept colicking we started short bursts of hand grazing, then for a while she was turned out on our garden (right by her stable). About 5 or 6 weeks ago the farmers who own the field right by our house allowed us to fence a bit off so we could start increasing turnout (she is still not sound on her foot, hence didn’t want her traipsing up and down to her normal field which is much further away).

All was going well and she was up to nearly 4 hours twice a day in the field, and had gone nearly 6 weeks without colic. She then colicked again. This was a gassy bout, she then colicked again about a week later (last Friday), also gassy, which is a change from her previous problems. Back to Google, which suggests the most obvious cause is rich grass. But what really confuses me is that she and her Shetland companion had slowly been eating down the ungrazed grass; but she didn’t colic until it was down to very short almost non-existant? There are lots of things going through my mind so that now I’m more confused than ever!

1. Buttercups – could those cause gassy colic?
2. I’ve been reading about sugar levels in grass. Could she have been eating “old” grass when it was long, but now that it’s grazed down, she’s eating the fresh new growth. Is that higher in sugars therefore more likely to ferment?
3. Sugarbeet – as the weather has warmed up I’ve taken her off this in case it was fermenting.
4. Weather itself. May was wet and cold in my part of the country. The colics seemed to coincide with it slightly warming up – change to the grass structure?
5. Weather again – could hotter weather actually increase the chance of excessive fermentation.
6. Soaked meals. I had started to cut those down to keep her weight in check. Possibly combined with the short grass, she wasn’t getting enough fibre (and/or water). Can’t do wrong for doing right, or something!
7. I read one tiny snippet on the internet about lack of food being a cause of gassy colic, so as above could the short grass and no hay, and reduced other meals be actually causing the problem.
8. If that was the case, would I be better just taking my chances with her normal field (10 acres, never fertilised so not lush but plenty to eat) or is that just asking for trouble? This is my main contradiction/confusion! Am I starving her into colic, or overfeeding her into it?? My gut tells me she can’t possibly be gorging herself on the tiny ¼ acre bare patch she is on.
9. Coligone – can you feed the liquid in feeds? I have been, but OH noticed the carton said not to. Would she be better on powder instead?
10. Time of day of turnout. Temporarily I’ve cut her grass right back and making sure she eats loads of her soupy meals instead. My plan is to work towards her staying out overnight instead. I’m also very very slowly trying her back on to hay, and if that works she can at least fill herself up a bit more on that, so she doesn’t pig out so much once out at grass.
11. Any other remedies for gassy colic that work? Charcoal? Fennel seeds? I’ve read US forums about people using Gas-x, which is an American human drug, the UK version seems to be windeze. Anyone actually tried this. I’ve started adding dried mint to her feed as I happened to have some from when she was first ill and went off her food.
I’ve never had to deal with colic before this horse, and before her injury she was so easy to keep, never suffered as a result of change to feed/routine/weather/exercise.

I am really unsure about what is the best course of action! Her foot is slowly getting better all the time, but she really needs a year in the field now – hard to do if it’s going to cause colic…Anything I’m missing or not considering? Any suggestions or advice very very welcome!

Earl grey and Green and Blacks for all suggestions :) Just none for the horse!
 
A vet told me that short wet grass causes colic as it ferments in the stomach, so we were always careful when it rained with susceptible horses and always made sure they had plenty of fibre before grazing (so a small net of hay or some chaff/fast fibre.)

With my current horse quantity is a factor as she gives herself gassy colic by overstuffing, so if that is a worry then maybe consider a grazing muzzle for the grass but still add fibre to the diet.

3am feeding - now that's dedication - you have my respect! :cool:
 
Needs must, re the 3am feeds! We've run out of insurance money, so I'm quite keen to avoid any more ulcers!!

That's interesting re the wet grass, I can't remember what the weather was like specifically so think I need a weather diary! I've done more reading since I posted and fructan levels do increase when the grass is stressed - ie short. So perhaps the overgrazing is the issue?

Seems like I have to hope for warm overnight temperatures, and hope that she copes when back on hay too, so that I can fill her belly in other ways :confused:. Night-time grazing also seems to be the best bet. That would mean no more 3am feeds at least :D

I hate having to interfere this much, I'd much rather she was just chucked in the field and left to it. But that seems rather a risky strategy at this stage...

ETS we have used a grazing muzzle, but she practically killed my mum after the first hour in it; it's also rubbing so going to have to try to customise it a bit first.
 
Get yourself a bucket of rite-trac from KER, kentucy equine research, you will only need one bucket but it will sort the ph levels out in the hind gut, also look into resolve cubes and releve which are specifically used for horses with colic and ulcers. These products do work they can be bought from www.bluegrasshorsefeed.com and i think saracens also do them. I know numerous race horses, eventers and sjers all treated successfully this way.
