It happens every year: Horses that have been turned out in pastures all summer must transition to a diet that contains far less fresh grass and far more hay. This means that the important fiber portion of the diet will have a lower moisture content along with a significant increase in the percentage of dry matter. Read further to learn how to avoid colic as horses transition from pasture to hay.
Throughout the fall and winter months, owners should continue to allow as much turnout as possible. Any change to a horse’s diet should be made as gradually as possible in order to avoid colic and other digestive tract upsets. Fortunately for horse owners, the move from grass to hay naturally follows this pattern as pasture growth declines and plants enter a dormant stage. Horses that have access to pasture will continue to graze, but the forage they ingest will slowly drop in moisture and lose its fresh characteristics.
Providing plenty of fresh, clean water is essential in every season, but it is particularly important when hay is being fed and horses are not getting much moisture from their forage intake. Extremely cold water is less appealing than water that has been warmed to around 50° F. Water at this temperature still feels very cold on human skin, but it is readily consumed by horses.
Access to salt, either loose or in a block, is also important. Sprinkling a bit of salt on grain or dampened hay will stimulate the horse to drink more water.
Throughout the fall and winter months, owners should continue to allow as much turnout as possible. According to Kathleen Crandell, Ph.D., senior equine nutritionist at Kentucky Equine Research, “Exercise helps to keep ingested material moving through the horse’s digestive tract, and pastured horses cover a lot more ground than stalled horses, especially if they are turned out with a buddy or two.” If outdoor exercise isn’t available, be sure that all horses get at least a few hours of riding, driving, longeing, or free exercise in a covered arena each day.
Monitor hay consumption while horses are in their stalls. If one horse is not consuming much hay, or if you find wads of partially chewed hay lying on the floor in this horse’s stall, he may need to have his teeth checked. Dental exams should be scheduled for all horses once or twice a year, but some horses, especially older equine, can develop problems between checkups.
When a new batch of hay is delivered, introduce it by feeding a small amount of the new hay mixed into the old, increasing the percentage of new hay gradually over five to seven days. This allows the microbes in the horse’s gut to adjust to the change and prevents upsets.
Inspect each bale of hay as it is opened and discard any hay that smells musty or shows signs of mold. Most horses will refuse to eat hay that is moldy, even if the mold is so slight that humans can’t detect it. However, extremely hungry horses may eat tainted hay, so it should never be fed and should be disposed of in an area where horses can’t reach it.
Research-proven digestive supplements can help horses that are prone to colic during feed transitions. EquiShure, a supplement developed by Kentucky Equine Research, stabilizes the pH of the hindgut. Changes in feed sometimes cause the pH to fluctuate wildly, which can set the stage for colic or laminitis.
