Handling the Heat

Handling the Heat

Learn how your horse’s internal thermostat works in extreme heat and ways to keep him cool

Maybe it was his name. The 18-hand one-ton Norman Cob named Texas found himself in a very uncharacteristic heat wave last summer in northwestern France.

“He can go 35 kilometers (22 miles) on an average day, and I usually drop him to 25 (15 miles) when it’s hot out,” says owner Fanny Chatel, who drove Texas in harness 1,550 miles across northern France last year. “But 40°C (104°F°)? That’s just too much to ask.”

Like many European countries, France experienced a major heat wave in 2019, bringing temperatures so high that the national equestrian federation had to adjust competition times to avoid putting horses at risk of heat stress.

Owners across the affected zones took measures to protect their horses, providing shade and easing exercise routines. For Chatel, that meant a four-day hiatus from her four-month escapade in Saumur—France’s equitation capital.

“I’m the one asking Texas to drive me on this exciting journey,” Chatel says. “It’s up to me to make sure he’s comfortable enough to do it.”

A Primer on Thermoregulation

Like most mammals, horses come equipped with ­complex—and very effective—ways to thermoregulate, or self-adjust their internal body temperature like a thermostat. The primary goal of thermoregulation isn’t comfort but, rather, survival, keeping the internal organs functioning properly at the ideal equine body temperature of around 99.5 degrees Fahrenheit, says Kristina Dahlborn, PhD, professor in the Department of Anatomy, Physiology, and Biochemistry at the Swedish University of Agricultural Sciences, in Uppsala.

Ambient temperatures affect body temperature significantly. When it’s cold out, the equine body works to conserve and increase internal heat. On hot days it dissipates and reduces heat, she says, through its interface with the air: skin. Thermal receptors in both the internal organs and the skin send messages to the hypothalamus—a small part of the brain responsible for many hormonal functions—which then activates various thermoregulatory mechanisms to trap or release heat as necessary.

While sweating is a good tool for dissipating internal heat, it is less effective in horses than in humans—simply because pound for pound and inch for inch, humans have much more skin surface area for their body size, says Dahlborn.

Further, due to their great muscle mass, horses produce much more heat than we do and must dissipate the surplus despite the skin area disparity, says Cecilie M. Mejdell, DVM, PhD, of the Norwegian Veterinary Institute’s Department for Health Surveillance, in Oslo.   

The horse can also use the respiratory system as a cooling mechanism. “Horses can’t pant like a dog, but they can increase their respiratory rate to dissipate heat from the airways,” as they exchange more air, says Mejdell.

The first line of approach for thermoregulation, though, is the skin’s efficient and expansive vasodilation system, she explains. When it’s cold, horses can “close up” the blood vessels in their skin so the heat in the blood stays deeper inside the body. As temperatures increase, the diameter of those vessels also increases, routing as much as a third of the horse’s blood at a time to the skin alone, close to the surface and away from the internal organs, which get the chance to cool off.

This system, however, comes at a risk: When too much blood gets pumped away from the internal organs, they can suffer oxygen deficiency—the basis of heat stroke, says Bénédicte Ferry, DVM, equine preventive health expert at the French Institute of the Horse and Equitation, in Saumur.

All About Sweat

When horses sweat, it evaporates off their skin into the air, pulling with it body heat, resulting in a cooling effect. Horses have a lot of sweat glands, and they can sweat profusely, ­producing 5 gallons of sweat in only an hour, says Ferry. However, that excessive production doesn’t help cool the horse much, since only about 25-30% of it evaporates. The rest sits on the body and runs down the legs.

On humid days the air is already saturated with water, so sweat doesn’t evaporate as well, says Grete H.M. Jørgensen, PhD, of the Norwegian Institute of Bioeconomy Research, in Tjøtta.

While the horse produces even more sweat (up to 7.5 gallons, says Ferry) than he would in the same conditions on a less humid day, the cooling process is less effective because the laws of physics interfere. Because less sweat evaporates, less heat dissipates from the body.

Horse sweat is dense with salts, which horses lose considerable amounts of when they perspire, explains Mejdell. To help horses replenish these reserves, provide a salt block and/or add salt to feed and supply unlimited fresh, clean water.

However, if a horse is sweating ­intensely, a salt block alone won’t suffice, says Dahlborn. “Sweat contains 9 grams of salt per liter, and a horse can lick about 20 grams per day,” she says. This means a salt lick prepares them for losing about half a gallon of sweat, no more.

Preventing Gastric Ulcers

How can horse owners help prevent equine gastric ulcers?

Preventing Gastric Ulcers
QUESTION:    What is the best way to prevent gastric ulcers in horses? I know there are various treatments available for horses that have been diagnosed with ulcers, but can horse owners in general prevent ulcers, and what is the best method in that regard? My understanding is that I should offer my horse:

  1. Free access to grazing if possible;
  2. Free access to hay with little to no fasting, if stabled for long periods;
  3. Alfalfa/alfalfa chaff fed with hard feeds; and
  4. Minimal disruption to his routine.

Perhaps you can confirm or elaborate on these?


ANSWER:      Gastric ulcers can affect upwards of two-thirds of all performance horses and can cause weight loss, colic, and poor performance. Ulcerogenic factors identified include low-forage diets, intense/increased exercise, high-concentrate diets, regular/prolonged transport, feeding at intervals, management/housing changes, water deprivation, weaning, moving to a new home, and prolonged stabling. Prevention is therefore key to keeping your horse healthy and at the top of his game. The most effective prevention strategy involves a comprehensive combination of feeding, management, and pharmacologic approaches.

By understanding the physiology of horses’ gastrointestinal systems, we can feed them in a manner that reduces their likelihood of developing gastrointestinal problems including gastric ulcers. Horses are by nature continuous grazers that eat coarse grasses 16 to 18 hours a day in natural settings. However, many performance horses have significantly restricted grazing access and often require additional caloric supplementation to meet their energy requirements.

This predisposes these horses to ulcer development. Feeding strategies veterinarians recommend to decrease ulcer incidence include allowing free access to or long periods of grazing; providing constant hay access during periods of confinement longer than six hours; using restrictor/slow feeders to promote “foraging” and saliva production; feeding frequent small grain concentrate meals; replacing simple carbohydrate calories with fats and fiber-based diets; offering alfalfa hay/cubes/pellets; and providing continual access to clean, fresh water. Of these feeding practices, maximizing consistent daytime fiber intake and providing free water access are the most important.

When used as part of a comprehensive approach, some oral supplements might be beneficial when administered longterm. Administration recommendations are directed at maximizing their effect (for example, when they are fed relative to known periods of gastric hyperacidity), but the scientific evidence of their efficacy is sparse, so ask manufacturers for published evidence before purchasing.

Minimizing stress relative to housing, common routines, and transport may also be beneficial. Horses housed permanently on pasture with light exercise are six times less likely to get ulcers than stalled, moderately exercising horses, and horses with constant access to forage are four times less likely to get ulcers.

Minimizing changes in routine and applying stereotypy-reducing strategies—particularly in young horses—may be beneficial, as these behaviors’ development is often associated with ulcers. Researchers have shown that installing mirrors in stalls and trailers can help reduce blood cortisol (stress hormone) levels and potentially lower ulcerogenesis.

Although these feeding and management changes can result in lowered ulcer incidences overall, these practices often cannot overcome the isolated, high-stress, ulcerogenic nature of showing/competing. Many horses in these circumstances benefit from pharmacologic acid reduction prior to and during competition. Owners can administer UlcerGard (omeprazole), the only FDA-approved and scientifically proven ulcer prevention medication in horses, as a once-a-day dose just prior to and during stressful events. Other unapproved medications (i.e., ranitidine) are used with varying success in treating ulcers—often combined with decreases in training/stress—but researchers have not extensively studied doses, dosing intervals, and length of administration for prevention.

The important thing to remember is that not all horses are the same, and they might respond differently to the recommended approaches. Consult your veterinarian when instituting comprehensive feeding, management, and medication programs to maximize your success and to help avoid any unforeseen complications.
