Horse Heat Stress Management: Tips For Keeping Your Horse Cool In Summer!
Summer is finally here. Winter blankets have been packed away with care. Bundling up for barn chores and breaking the ice in your horses’ water buckets are now distant memories. As you bring your fly sheets out of storage and hang up fans, it’s time to make a plan for how to help your horse beat the heat this summer.
Understanding Your Horse’s Basic Needs
Not only do the summer months bring warmer temperatures and longer days. They also bring more opportunities to ride and compete with your horse. As temperatures rise, so do the risks of your horse experiencing a heat related stress. This includes dehydration and heat stroke. Keep an eye on your horse and modify your training and horse care program to make the most of your summer riding opportunities.
Water
The average 1000 pound horse at rest drinks 8 to 10 gallons of water a day. When temperatures rise above 70° F, horses in work can drink twice as much. Make sure they have access to clean, fresh and cool water at all times, whether your horse is turned out or in his stall. By drinking cool water, they will be able to lower their body temperature on their own. If your horse isn’t a big drinker, you can encourage water consumption by providing free choice salt blocks in your pastures and stalls.
Shade
Providing shade to your horse throughout the day is almost as important as making sure your horse has access to water. Whether you board in a barn or in a field, shade is needed. Obviously a horse in a stall is provided shade from being indoors, however they will need shade when they are turned out. Make sure your pastures offer several shade options.
If there aren’t shade-bearing trees in your field, offer an escape from the sun with a run in shed. With run-ins, the higher the roof the more air circulation and cooler the shed will be. As shade and water go together in importance, place your water troughs in shady areas.
Do you have a field that doesn’t have much shade? Alter your turnout schedule. Either turnout your horses at night, or if you have a horse that doesn’t require a lot of turnout put him in the field early in the morning. Both of these options will let your horse beat the heat and powerful rays of the sun.
Conditioning
Before the temps rise too much, learn how-to assess the body condition of your horse.
If your horse has been in regular work since the winter weather subsided, he will be more likely to be able to handle the rising temperatures. Horses that are out of shape, overweight and even thin under-muscled horses have a hard time dealing with the extra stress associated with heat.
If your horse hasn’t been in a regular exercise program, slowly build up their fitness and stamina as the heat and humidity rises. This slow and steady approach will help ensure your horse stays healthy and not overstressed this summer.
The Importance Of Equine Electrolytes
You know summer is here when your local Southern States and tack shops start expanding their section devoted to electrolytes.
So what are electrolytes and how do they help your horse in the summer? According to Dr. Marty Adams, Equine Nutritionist for Southern States, “Electrolytes are minerals in the horse’s body fluids and tissues that are involved in muscle contraction, thirst regulation, nerve function and maintenance of blood pH.”
Electrolytes can be found in your hay, pasture and Southern States horse feed. However, horses in work, (especially those who travel to compete) need additional electrolytes to maintain good health and perform at their highest level.
Like humans, horses use sweating as a way to cool off during periods of warm weather and while exercising. When a horse sweats, not only is water lost, but important electrolytes like sodium, chloride and potassium are lost. If too many electrolytes are lost serious problems like fatigue, muscle cramps and horse colic can occur.
Dr. Adams says, “When looking for an electrolyte for your horse, sodium chloride should be listed first on the ingredient list. Second, followed by potassium chloride.” There are two types of electrolytes, salt based and sugar based. While sugar based electrolytes are highly palatable, you won’t meet your horse’s daily salt requirements without feeding a lot of the sugar-based electrolyte.
Electrolytes can be given to your horse in a variety of ways. You can add water and administer via dosing syringe, add the electrolytes to your horse’s feed or add the electrolytes to their water. Each way works equally as well, just figure out what your horse prefers to ensure they are consuming the added electrolytes.
Horse Sweat Is A Good Thing
Often times you hear the phrase “no sweat” when people are referring to something that isn’t a problem. When it comes to horses, no sweat is a big problem. During a hot, muggy day it isn’t uncommon to see horses drenching in sweat when doing nothing more strenuous than simply grazing in the field. Although they may look uncomfortable, these sweaty horses are far more comfortable than their non sweating counterparts. Sweating helps regulate body temperature.
Anhydrosis in horses is the partial or total inability to sweat—and is a problem that can be potentially life threatening. When a horse is unable to sweat, he is unable to keep his internal organs and brain from overheating. Unfortunately no one knows what causes this condition and it can affect any breed, though it is most commonly seen in the Gulf Coast states including Florida and Louisiana.
Signs Of Equine Anhydrosis
- panting
- poor tolerance to exercise
- dry hair coat
- hair loss (especially around the face and a reduction of sweat)
Immediately contact your equine veterinarian if you think your horse may be experiencing anhydrosis. While there is no cure, you can manage a non sweater in a variety of ways. You can relocate your horse during the summer months, limit physical activity, install barn fans and misters or manage through supplementation. Studies have shown that non-sweaters can benefit from additional Vitamin Eand Selenium supplements. It is thought that these levels are low in horses with anhydrosis.
Adjust Your Horse Care Schedule
When we hit the beach this summer, we are often reminded to avoid the hottest part of the day. Typically is is between 11 am to 3 pm. We are told to apply ample sunscreen. This same rule should apply when trying to determine when to exercise your horse during the summer to try and avoid the heat of the day. When possible try to ride either in the morning or late evening, depending on what works best for your schedule.
In addition to changing the hours at which you ride, change the duration of your ride. A short workout in hot, humid conditions is the same as a longer workout in more pleasant weather, in terms of stress placed on the horse. Take plenty of rest breaks, to help your horse cool down during your exercise session.
After you finish exercising your horse, don’t just drop him off in his stall like a hot potato. Take your time and properly cool him off. Take him for an extended walk, hose him off and brush the water off scraping the water off to speed up the cooling process or put him in front of a fan.
Trailering Your Horse In The Heat
When competing this summer, not only do you need to think about how you will perform your best when you arrive at the show, you need to come up with a plan for how you will safely get your horse to the competition. The heat and humidity of the summer can create oven-like conditions in your trailer. So what can you do?
- If you don’t currently own a trailer, consider buying a “cool” trailer to ship your horse(s) in. Studies show that dark exterior colored trailers can be 20-30° hotter inside than trailers that are white or silver in color.
- Look for trailers that have large windows for maximum airflow and ceiling roof vents to draw air into the trailer. If possible, take a test ride in the trailer yourself to see what the airflow and temperature conditions are like when temperatures rise.
- Even when the weather is cool and humidity is low, traveling is work for a horse. Riding in a trailer can fatigue a horse. They constantly have to work to balance themselves in the moving trailer. Add in warm temperatures and you can easily have a horse that arrives to its destination dehydrated and fatigued.
- To minimize fatigue, alter your travel schedule. Transport your horse either in the evening or early in the morning, whatever is the coolest part of the day. Before putting your horse on the trailer make sure you have opened all the windows and air vents to get cool air circulating prior to loading. If you have fans on you trailer, turn them on as well.
- To minimize the impact of heat coming up from the road, place rubber mats on your trailer floor or bed the trailer down with shavings. Heat comes from the sun beating down on the trailer. It also comes up from the black asphalt the trailer is riding on.
- Hose your horse off prior to loading, in an attempt to keep them cool. Use a fan spray hose head like the Gilmour Fan Watering Wand to make your horse happier.
By modifying your trailering routine you will be able to ensure your horse travels as comfortable as possible regardless of the weather.
Barn Fan Safety
Each summer horse owners everywhere put fans up in their barns . This helps to cool their horses off as the temperatures rise. However, not all fans are appropriate for barn use. Most horse owners run out to their nearest hardware or discount store to stock up on box fans for their barn.
Before you follow suit, make sure you are buying a fan that is designed for agricultural use. Do not use a box fan designed to be used indoors in a residential situation. Fans (like the Ventamatic 24″ Direct Drive Yellow Tilt & Stand Fan) designed for agricultural use have motors sealed up to prevent dust and dirt from interfering with the motor and starting a fire. In addition to having unsealed motors, inexpensive box fans also have light weight cords which can eventually expose their wiring over time. Take a look at our other barn & horse fans online.
Barn fires are caused every year from faulty fans and improper installation of fans. To prevent the potential for fires, in addition to only using agricultural fans in the barn, only run fans when there are people in the barn. Turn fans off at night! Most of the time barns are reasonably comfortable at night. Especially if you can open up windows and doors in the barn. Vacuum or blow off dust that accumulates around the fans that are placed on or in your stalls.
When installing fans, make sure you keep the cords out of the horses’ reach. One bite to a cord can cause a short circuit and potential fire. Remember horses aren’t the only ones to potentially bite the cords, raccoons and mice can also interfere with your cords. Always unplug the fans when not in use!
Another option when it comes to cooling down your barn is to get two large agricultural use approved floor fans and put them at either end of your barn aisle. These large high power fans do a great job of circulating air throughout the barn during the day.
Enjoy Your Summer
Summer doesn’t have to bring your equestrian activities to a halt. By changing both you and your horse’s riding routine you can both enjoy your summer while staying healthy and competitive. When in doubt whether to ride or go to the pool when temperatures are scorching, play it safe and go for a dip.
