Laminitis or founder, as it is commonly called, is inflammation of the laminae of the horse’s foot. … A horse suffering from laminitis experiences a decrease in blood flow to the laminae, which in turn begin to die and separate. The final result is hoof wall separation, rotation of the coffin bone and extreme pain.
To avoid grass founder:
How long does it take for a horse to recover from founder? … Recovery time largely depends on the amount of damage done to the laminae, and sometimes, horses never fully recover. But if there is little to no rotation or damage to the coffin bone, the horse could have a full recovery in 6 to 8 weeks.
So alert your veterinarian as soon as possible if you detect one or more of the following:
Summary of Treatment
Remove the horse’s shoes and roll the toes if there is good sole support from the rest of the wall of the hoof. You want the sole concave with respect to the ground. The toe and its associated sole should be off the ground.Do not do any trimming on a horse with poor walls and thin soles.
There is no fructan in warm-season grasses, yet horses can still founder on them. Since the same environmental conditions that create high fructan concentrations also increase sugar and starch levels, it’s best to just limit all NSCs.
You can founder a horse by putting them on an insulin drip for 48 hours, or simply by turning them out onto the equine version of a Snicker’s bar — a green spring pasture. The high sugar content of the grass signals the body to produce even more insulin. Take a look around the dry lot.
Feed grass hay, possibly a little alfalfa hay, or rinsed sugar beet, BUT stay away from corn, oats, barley, and especially stay away from sugar as molasses. Feed extra fat in the form of oil or rice bran if you need to get energy into the horse.
It is possible that grass with high WSC and NSC could be safe for ID horses, as long as the ESC and starch are below 10% (or whatever that horse’s limit is – horses with a stronger genetic tendency for ID or that still have weight to lose or aren’t getting as much exercise as they need may require a lower threshold – …
DON’T: Ride yet!
It might be tempting, especially if your horse “seems” okay, but riding a post-laminitic horse is definitely ill-advised in the early months. If you want that laminar interface to reconstruct as it should, you’ve got to keep the weight off—specifically, your weight.
Horses on high-quality fields, such as those with dense, well-managed, fast-growing grass, were 19 times more likely to develop laminitis. “This suggests that grass intake may either be the cause or the final triggering factor for many animals developing new laminitis,” wrote the authors.4 мая 2020 г.

Hoof rings, also called growth rings, occur in healthy hooves and are typically the result of variations in diet from season to season, especially in horses whose diets are composed of primarily forages.
When diagnosing laminitis, the vet or farrier will first feel for a digital pulse. … Next the vet or farrier will use hoof testers to squeeze the hoof. Laminitics tend to react with pain when squeezed around the toe area. In really severe cases, they will react just by thumb pressure over the sole at the toe.
