STUDY: SOME HORSES HAVE A TASTE FOR SAND
A study from Finland suggests that some horses develop sand colic not because they accidentally ingest dirt with their meals but because they actually like to eat soil.
University of Helsinki researchers conducted an online survey of owners whose horses had been radiographed at some point to check for accumulated sand. Each respondent was asked a variety of questions including which clinical signs prompted a call to the veterinarian, how much sand had accumulated in the horse’s gut and how the horse was managed at that time. Data from a total of 447 surveys were used in the final study.
The researchers discovered that, in many cases, the veterinarian was called in because the owner suspected that sand had accumulated in the horse’s gut, and abdominal radiographs confirmed the suspicion. Diarrhea, colic and poor performance were among the signs of trouble most commonly reported by the owners.
Some horses develop sand colic because they actually like to eat soil.
“Most often the poor performance is subtle,” says Kati Niinistö, DVM. “The horse is not jumping as nicely as it used to, not cantering properly, or just does not want to move forward. Many times people don’t link the changes to sand accumulation, but only realize that the problem disappeared when sand was treated. If we don’t find anything special in the lameness exam, but the horse is unwilling to move and maybe not using the hind limbs as before, we sometimes take a radiograph for sand.”
In addition, the data showed that horses exhibiting signs of colic were more likely to have significant accumulations of sand in the gut than were other horses.
