This mare was not in obvious distress, just wasn't "quite right." So, we were in constant contact with 2 different vets every time any little minute thing changed, hoping things would correct themselves but prepared to take her in if they didn't. The first vet said he had received calls on something like 5 - 6 colics in this area within a little over an hour. He commented that there must be something going on with the weather or temp. or pressure or something to bring on this little colic surge.
Fast forward, the mare went in to the vet and from there went to Purdue. Purdue took her into surgery and was prepping another to go in after this mare; they were also having a "colic surge." The person taking care of the mare at check-in talked about a theory (don't know who's theory this is or how widespread it is) that relates extreme temp. changes to colic. Apparently, the theory relates sudden drastic temp. changes to changes in water needed to maintain proper hydration, and the inability of some horses to adjust to this change quickly enough.
So, for example, it's really cold and a horse needs X amount of water to stay properly hydrated. Temperature suddenly increases and horse now needs Y amount of water to stay properly hydrated, but it's brain doesn't tell it's body to adjust to that amount quickly enough. Temperature drops again and now horse is dehydrated but doesn't "realize" it... dehydration continues... colic follows.
I've also done some colic googles and internet searches and have come across, time and time again, comments about this being "colic season" or "a bad time of year for colic," etc.
All of this leads me to wonder if there is really something to this temp. swing = colic thing. The temp's here have been ridiculous lately and are fluctuating beyond control. Example: Sunday was very warm (short sleeve shirt weather,) everything was melted and muddy, Monday was similar, then yesterday the temp. dropped dramatically and we had sleet, hail, snow and ice with winter weather advisories.
What do you all think? Does this theory hold water (no pun intended) and does anyone give salt or electrolytes during temp. changes to encourage increased water consumption?
(By the way, at last update, the mare was doing fine and recovering nicely.)
