No studies confirm it, but vets (and I) will tell you that when barometric pressure changes, colic cases go up.
So today, when the first wave of pre-winter stormy weather was predicted to hit our area, I turned up the dial on colic vigilance.
Almost every colic case we've had has occurred during a storm-weather period. Unpleasant as they were, those episodes taught me a few things. Such as:
* Make sure everybody has fresh, clean, inviting water to drink. The more water horses can be encouraged to consume, the better lubricated their digestive tissues will be, and the better they'll be able to digest their feed.
* Prepare for the fact that horses will go through more roughage, in the effort to keep warm. To be processed without compaction, this extra roughage will require extra water consumption. See above.
* If you can bring horses in out of inclement weather, where they have rain/wind protection, their need for roughage intake won't be as great as if they were left outside to "tough it out." See above.
* Don't pick stormy days to make big changes in the feed or exercise programs. Kids get tummyaches when that happens, and horses do, too. Except their tummyaches are called colic.
