How to keep horses cool in hot weather? As summer drags on, heat can become a serious problem for many horses.

Sweating is the primary way horses cool themselves. Experts believe that prolonged, consistently high sweat rates can lead to “exhaustion” of the sweat glands. In horses, this may result in anhidrosis, or the inability to produce sweat adequately. It is crucial to address anhidrosis and find other ways to keep horses cool because it can pose a serious health risk to horses in warm climates.

Here are a few tips to keep in mind when trying to keep your horses cool this summer.

1. Fresh, cool water

Hydration is critical during hot weather, but poor water quality can severely limit your horse’s intake. Most horses don’t like to drink hot water, so it is best to provide fresh, cool water daily. Dark-colored troughs or buckets placed in direct sunlight will absorb heat and warm the water quickly.

Keep horse water troughs and buckets clean and free of algae to encourage drinking. Remember, it can be hard to see accumulated algae and debris at the bottom of a dark-colored trough. Another tip: overfill water buckets and troughs to provide moisture for your horse’s hooves, especially in dry climates.

2. Salt and electrolyte supplementation

Feeds do not contain enough salt to meet a horse’s daily sodium requirement. Therefore, an additional source of salt is always recommended. At a minimum, a salt block should be available free choice. However, horses are not natural lickers and may not lick enough voluntarily. Top-dressing their feed with 2 oz plain salt per day is a good way to ensure they get enough.

In the “sweating season,” whether due to temperature or workload, salt should be switched to a quality electrolyte. This will supply important minerals like potassium and calcium, in addition to salt, that your horse loses through sweat. The best electrolytes will be mostly minerals, not sugar.

3. Summer horse shelter

We can all appreciate how much cooler it is under the shade tree in the middle of summer versus being out in the full sun, and your horse feels the same way. If there are no trees in your turnout areas, providing a run-in shed or even a fabric sunscreen as a horse shelter can make a big difference in helping to keep your horses cool.

Horses cool themselves primarily through evaporative and convective cooling. To help them, apply cool baths or use sprinklers to keep your horses more comfortable and to decrease their need to sweat as much. Moving air increases both convective and evaporative cooling. If the breeze isn’t blowing, provide a fan to move the air. Some farms even use large golf course fans to keep their horses cool in pastures. Finally, remember it may be more comfortable outside in the sun than inside a stuffy barn with poor airflow.

4. Exercise and heat stress in horses

Metabolic heat from exercise is another primary heat source for horses; therefore, it is best to confine strenuous exercise to early morning or later evening hours when ambient temperature and humidity are the lowest. Alternatively, you can give yourself and your horse a break from hard training during the hottest summer months.

To avoid additional heat stress, postpone events such as vaccination, weaning, changing barns, moving horses between groups, etc. If any of these events must occur during the hottest days of summer, try to do them during the coolest hours of the day.

Even though summer can be a sweaty, uncomfortable time, these tips can help your horse stay healthy and happy year-round.

Seasonal Diet Changes for Horses: Pasture quality fluctuates with every season, but the shift in quality from summer to fall is significant.

During the fall, there are often warm, sunny days and cool nights. Pasture plants manufacture sugars in the presence of water, carbon dioxide and sunshine. They then use those sugars to fuel growth during the night. However, when nighttime temperatures drop in the autumn, it becomes too chilly for plants to grow and the sugars are stored for later use.  This leads to a concentration of stored sugars in the plants. In turn, it may increase the risk of digestive upset or laminitis in some horses.

Horses at most risk are those that are significantly overweight or those that have trouble managing normal blood sugar levels and are sensitive to sugar content in the diet.

Changing seasons also mean drastic swings in weather conditions and temperatures.  This, combined with a major diet adjustment of moving from pasture to hay, can increase the chance of digestive disturbances.

While not scientifically proven, many horse owners and veterinarians have experienced what appears to be an association between changes in barometric pressure and the incidence of colic episodes in horses. A dramatic drop in temperature often causes horses to drink less water. At the same time, horse owners will often increase the amount of hay fed to help horses stay warm.  More hay and less water consumption together may lead to impaction colic.

Hay:

As we move into fall and winter, hay becomes the major forage source for many horses.  Switching from pasture to hay or getting a new supply of hay represents as big a change to the horse as a change in grain. These significant dietary adjustments should ideally be made gradually to decrease the risk of digestive upset.

Horses should be fed good-quality hay to maximize nutrition and minimize potential digestive problems. Good-quality hay, of any variety, will be clean and have a high leaf-to-stem ratio, small-diameter stems. In addition, few seed heads or blooms, a fresh smell and appearance, and a bright color (faded, yellow or brown color may indicate aged hay or poor storage conditions). The maturity of the plant at harvest determines the hay quality more than any other factor. Young, leafy, immature plants contain more protein, energy, and minerals than older plants with thicker stems.  Also, as a plant matures, it contains more indigestible fiber (lignin). This reduces nutrient availability. Lower-quality hay must be supplemented with higher-quality feed to maintain horses’ good condition and health.

Fall is a season of transition and an important time to evaluate the quality of forage available for your horse and whether the grain ration is appropriate and adequate to meet your horse’s nutrient requirements. When winter arrives, horses must be in good condition to be able to withstand colder temperatures. Adjusting grain rations in the early fall will prevent weight loss due to lower-quality forage and, if horses need to gain weight, there is still time for a thinner horse to gain some before the cold weather really sets in.
