best to follow your vets advice as they will be able to comment on your individual pony - These things can vary on the horse/pony and the severity/cause of the laminitis.
As a general guide, most laminitics at the box rest stage will usually be fed on hay (soaked for 24 hours), with maybe 2 very small feeds of chaff type feed suitable for laminitics to put supplements/medication in.
Box rest will vary, anything from a couple of weeks to months and months. Generally, no walking out at all for the first few weeks, and in hand walking very gradually introduced when the vet advises.
Exercise and turnout will depend very much on your pony/horse, facilities etc. Again, the vet will know your situation best, so consult them.
If you are struggling with feed, ring one of the feed companies, they will be able to advise on their suitable feeds and supplements.
my tbx mare got it last year from fertilised grass for the 1st time(she was 17)
she came in straight away,had sedalin to improve the blood flow in the feet and 2bute a say.she had soaked and rinsed hay and straw(about 6 slices) and a small handful of hifi lite with minerals and vits in.she had a deep shavings bed-about 12 bales in 12x12.and frog pads on.
my mare was turnout out in a sand paddock(with only sand-nothing growing on it at all) with ad lib soaked hay and straw-she had been in for about 8 weeks (on soaked hay and straw,braod spec mina nd vits, on thick shavings bed with frog pads on)
but she was so stressed by it she box walked and was lame from muscular issues.
usually i would want them sound for 2 weeks before turning out.
i walked her out the stable after she had been in for 2 weeks to see if she was better,but until she hjad been in a month and had no improvement the most she was allowed was to stand on the yard with the sun on her for a groom.
she was on the sand area for about a month so her feet were fully recovered.
movement is important once the lamini are stabilised as this helps improve blood supply and regenerate.the sand area was perfect as it was about the size of 5 stables and soft so she could move about but not too much and her feet were supported by the sand.
then i started off grazing her in ahnd for 5mins twice day and build up.she has unfertilised grass only and was in the sand area the rest of the time.
she had a muzzle on/came in in the daytime last year if it was sunny or if they went on a rested part of field with longer grass.she seemed fine without in on restricted grass in cloudy weather as there is less sugar in the grass then.
she lose too much weight that year and looked really poor going into winter-she wasnt over weight when she came down with the lami.
this year shes been fine without one and out 24/7 on grass and with soaked hay.
her two sets of xrays showed no changes to her pedal bone position and shes been fine ever since.she gets a trim every 4 weeks to keep her feet balanced and she is barefoot.
if its really sunny(!) i sometimes bring her in in the day.
shes fed happy hoof,topspec comp and alfa a oil.
I would follow you vets advice on when to turn out. The old pony mare that lives with my boy is kept in a small paddock with old hay twice a day to make sure she has enough fibre through her gut.
When she was on boxrest for 8 weeks she was given old hay twice a day and 6kgs of dendie hi-fi lite a day in 3 feeds to make sure her digestive system kept functioning. Feeds that are high fibre and low protien are safe to give.
Even laminitic ponies need to be fed something if their grazing in restricted or removed.
I hope your pony is ok.
Follow your vets advice.
Mine was on box rest for 4 weeks, then had a remedial trim, came off medication and started walking in hand and limited turnout (she was sound and the vet and farrier had seen her x-rays). Building up from 1 hour turnout (muzzled) and 15 minutes walked in hand.
Whilst on box rest (and after) she was allowed 24 hour soaked hay and a handful of Happy Hoof with vits and minerals.
I agree, your vet will come and assess, I was lucky with mine, he'd pop in on the way past on his calls for free (yes am aware was VERY lucky), but as for how managed mine, Pandora was on box rest with ad-lib soaked hay, she wasn't restricted with the amount of hay she had, it was soaked overnight in a huge bin, great things those water butt's are for soaking a few nets in....
Feed wise she got a slight handful of hifi lite, a spoonful of speedibeet to mix the bute in (only way could get it in) and at first that's all she had, gradually she had max ox, chromium yeast and top spec comp supplement (not the pellets!) introduced to her feed, she's been fabby on that ever since tho am still watchful with her because am aware it's there like a ticking bomb if the wrong thing happened.
Incidentally research is showing big links between so many lammy cases and white clover in fields, this of course won't apply to a lot but for some on restricted grazing that happens to have clover and are wondering why lammy is still happening....
so many causes, Pandora's is EMD, while in one way was good to find out, in the other it makes her one of the harder types tbh tho she has a healthy life now
