This is something I wrote about Sand Colic because there have been quite a few questions on it, anything people would like to add would be great and any mistakes in information let me know:
What is Sand Colic and what are its causes?
Well first off colic is a stomach pain, this means that sand colic is a stomach pain caused by a build up of sand. The causes of sand colic are obvious, Sand colic is the result of sand building up in the intestinal zone of a horse. When a horse is eating meals and it is picking up the final scraps the horse may possibly pick up some sand as well, this can also happen when grazing. Although some horses mainly foals will eat sand deliberately.
Preventing Sand Colic:
Preventing Sand Colic can be a very hard thing to do, I myself know that when a horse is in a sandy paddock can be extremely difficult. The best supplement I have found to help prevent Sand Colic is Psyllium. Psyllium can come in several different forms, the one I use is a husk. I give one cup of Psyllium Husk a week, but this will range because of the size of the horse and the amount of sand on the ground, it is good to discuss this with your vet or someone at your local tack shop.
Results of Sand Colic: Sand Colic can be fatal if not dealt with in a major situation, the level of Sand Colic depends on the amount of sand the horse has eaten and the strength of the horses systems.
Signs of Sand Colic: Some of the signs of Sand Colic are rolling out of discomfort or repetitive rolling, pawing at the ground, depression, going off their food or water, kicking at their stomachs, diarrhoea or laying down for a long period of time.
What to Do If a Horse Has Sand Colic? If a horse has sand colic the first thing you should do if you think it is serious or are un sure you should contact your vet. If your horse is laying down it is obviously comfortable so leave it laying down. People use to get their horses up and walk them around to help it pass through the horses system but now people just leave their horses to be.
