not so TINY BUBBLES...




From Jim: Well, we've got a storm on the way, big pressure gradient, low pressure coming. That means a fair chance of weather colic. An equine's gut is around a 100 feet long, counting the large and small intestines and the cecum. That last item, the cecum, is located where the large and small intestines find each other. It's a big old fermentation vat. It's full of bugs. In polite company, they're probiotics. But they're really bugs, bacteria. They play a real important part in the digestive process by breaking apart the forage matter that equines eat. The process creates a by-product, methane gas. You may have gotten a whiff of it once in awhile. Whew! OK, so here comes the big science lesson for the day. An equine's gut is a closed system. It has, or tries to have pressure around what the atmospheric pressure is. When gas develops from digestion, they vent it. Thus, the sniff. Sometimes, when there's a big change in barometric pressure. The internal gases are caught at a higher pressure and the falling barometer causes them to expand to take up more volume and, thus, reduce the pressure, to equalize it. That can and usually does make for "gas pains". We've probably all had them sometime. Our equine friends don't do well with belly aches. They stretch and lay down and roll and generally are miserable. Colic is bad because it's a symptom and the causes can be life threatening. If you have the slightest doubt, call the vet. Colic is a true medical emergency for equines. We usually dose the coliced critter with banimine. A listen for gut sounds is useful. I use a stethoscope, but an ear on the flank works too. Gas makes a high pitched squeak or squeal, kind of like rubbing your fingers on a balloon. There may or may not be the usual gurgling and plumbing sounds. The vet needs to know that. I prefer injections because I can confirm the dosage. That can help with a diagnosis. The degree of relief is telling. Also the time it buys might allow for some gas passing and bowel movement. Again, colic is serious business and the vet is the best line of support. We are in touch with the vet as soon as we notice the signs of colic. That gives him a head's up and he's got an accurate time line. So, we've got a storm on the way. It's a pretty good one, they say. We'll watch the herd very carefully for the next few days. The animals that have had gas colic will get an extra look or three. I suppose I better check on our banimine supplies, syringes and needles. Hope I don't need em!
