Turn down the heat
“The solution is to turn down the heat and get rid of the humidity by increasing air flow,” Freeman said.
Some farm operators have reported beneficial results by installing exhaust fans that move air when the humidity rises. There are methods to make these systems automatic by installing reostats that respond to humidity levels.
Another problem is that while the ideal temperature for horses is around 45 degrees to 65 degrees Fahrenheit, this “ideal range” may be neither cost effective nor a way to promote equine health.
“Increasing the heat of a barn above 55 degrees Fahrenheit not only can be expensive, but it also may have negative effects when moving horses out of the barn into colder temperatures,” Freeman said.
Equine managers also need to remember that horses under artificial lighting programs for reproductive or show reasons will shed hair. Therefore, special considerations must be given to protect these animals from cold, windy and wet weather.
Even though hair growth is largely a photoperiodic response, warm environments assist in keeping hair short. Adequate hair cover is extremely important during cold conditions, providing the horse with needed insulation to combat the cold stress of near freezing or freezing temperatures. Frequent movement into and out of heated barns from cold outside environments may in itself be a significant source of stress that can be avoided.
Freeman said one alternative is to maintain barn temperatures at around 45 degrees to 55 degrees Fahrenheit and use blankets to keep horses with short hair coats protected from cold temperatures in and outside of the barn.
“Part of the problem with maintaining proper barn temperature is that people working in the barn often like it a bit warmer than is recommended for the horses,” he said. “Horse managers should maintain barn temperatures at a level that will help promote healthy horses and not at a level dictated by a worker’s personal comfort.”
This might require periodic checks by the barn manager to ensure temperatures are set at the proper level.
“It’s often just a case of human nature. If you’re cold, you don’t think twice about turning up the heat a bit,” Freeman said. “But that oversight can cause health-related problems for horses, which in turn can mean money lost to the horse owner.”
