Please be careful with the fall grass as it comes back after the rain, it’s just like spring all over again. I saw several laminitis cases earlier this year and it’s something you definitely don’t want any part of.
As we approach the start of fall and the temperatures start to drop, here is some important information to know regarding fall laminitis.
Fall laminitis refers to cases of laminitis or founder that occur in the autumnal months. Although laminitis can happen in any season, anecdotally there seems to be an uptick in the number of cases in the fall.
Why could this be?
• As the days get shorter and colder, grasses have been shown to respond to this stress with higher sugar concentrations. Diets with higher simple sugar concentrations may increase the risk of laminitis.
• Decreases in exercise may cause increases in body condition. Fat or obese horses are at risk of developing laminitis.
• Horses naturally have increased levels of certain hormones in the fall. If you have a horse with PPID (previously referred to as equine Cushing’s), the increase in their cortisol levels could put them at risk for laminitis.
If you have questions concerning fall laminitis or are concerned that your equine companion may be at an increased risk, contact your equine veterinarian so that they can properly evaluate your unique situation.
Thank you to the Horse Owner Education Committee for providing this information.
