good to hear she is pooping... did you check the poop? Is she passing any sand? How does her poop look? Normal? Runny? Hard? That's important too..
If you are going to try the beet pulp today, use the molasses type to start her on it, seems it tastes better.... use 1 part beet pulp, 1 part WARM water (soaks faster), and 1 part WARM apple juice....soak for 30 mins.... it will swell up alot, so just use a small container so that you r not wasting it because you will not be able to keep it long after it soaks...it ferments pretty fast in the heat....
The gatorade (adds electrolytes) will just assist her in fighting dehydration if she is not drinking alot of water... at least 5 gals a day is "normal" for a horse... you really need to find a way to keep track of how much she is drinking... you said she has a tub? Of water in her stall? Then get yourself a 5 gal bucket (empty at any home improvement store is just a few dollars) and use that to refill the tub, marking the outside of the tub with duct tape at 5 gal levels..that will help you determine amounts she is drinking... and make sure you r giving her CLEAN, FRESH, COOL water at least twice a day....
And, in the future, you can feed beet pulp without soaking it.... just small amount daily UNSOAKED is what I feed.... I only soak if I am trying to hide something they do not like...and I don't really "soak", I just add liquids at feeding time ... I give my horses 1/2 scoop (probably 4 cups) dry mixed in with their feed EVERY night.
And just so you know... I am no expert, but I am 50 years old and have only had 1 colic and I live in Florida (the land of colic!!!)...
I did check her poop and she is passing a bit of sand. Her poop looks normal as far as consistency (not runny, not hard).
She used to eat beet pulp on a regular basis.. i'm going to pick some up today so she can start on it at dinner time.
I also added gatorade to her water to help keep her hydrated. I measured out how much water her tub holds and it looks like she drank about 8 gallons yesterday and had sucked down about 3 today by the time I left around noon.
I used to feed soaked beet pulp twice a day every day when I had my horses at home. Now that I am boarding I no longer feed it because I can't always get there every day and my bo said its too difficult to have to soak. I think i'm just going to have to make an effort to really get out there daily so they can have beet pulp once a day. ... it kind of makes sense that when I had her at home she never got sand colic but now that i'm boarding, just two short months later she gets sand colic. I think it really does have to do with not getting the beet pulp anymore.
When I left around noon today she was picking at her food every so often so i'm hoping she will continue to do so. She's much more alert today, no laying down and/or rolling, nickering for food.. praying we are heading in the right direction!
Can't thank you enough for all your thoughts and suggestions!!
