Over the past week, we have had 4!! yes, 4! extremely complicated colic situations with horses at my stables. All 4 of them are in paddocks next to each other, so the dirt composition is the same......dirt mixed with alot of sand . Apparently, one horse likes to eat dirt by the mouthful....eww. ) 1 case was not entirely sand colic related; his intestine/ colon?? flipped over and got squished inside his abdomen, causing impaction. He had to be rushed off to the vet for some immediate treatment. At this time, he is doing better. The other 3 have sand colic, 1 has approx 8 inches of sand ( could that be right????) and all are on treatments as prescribed by the vet. The sad part is, is that the 2 severe cases belonged to the same family! Imagine both of your horses colicing at the same time! They even did monthly/ bimonthly Metamucil/ Psyllium treatments. Neverless, their vet bill has added up to approx 4 K. (Not exactly pocket change for some of us ) So, As for my boys, they are not showing any signs, 1 is out in a large dirt pasture, 1 shares a medium sized paddock with another horse. Now, I have not treated either boys with monthly Metamucil/ or any other Psyllium powder and so far so good. However, they do get approx 3/4 to 1 cup of a ground flax seed/ supplement mixture (Horse Health Product Horseshine Omega 3 Flax Feed Supplement by Omega Fields) daily. (Or at least 5 days per week). So my questions are as follows: 1) Can flax seed be just as beneficial as psyllium for moving sand out of the gut? 2)What are everyone's maintainence schedule or how do you prevent sand colic (esp those in sandy terrain)? How much do you give for how many days per week? 3) What products do you prefer? 4) Is the generic Metamucil or (Walmart/ Target) brand just as good as the horse brand named products? Please share your knowledge, insight, personal stories, and any additional info or comments that you may have!!!!
