Ventilation
A 1000-pound horse releases 2 gallons of moisture into the air each day through respira-
tion. A four-horse barn must thus deal with more than 8 gallons of water vapor per day, not
counting the additional moisture created by the evaporation of urine and manure.
Warm air can hold a certain amount of water vapor, but as the temperature drops, it
loses as much as half of its water-carrying capacity. Moist air rising from a horse's stall
condenses on the underside of uninsulated roofs, causing dripping, dampness, and some-
times ice formation. Damp air contributes to respiratory ailments, stiffness, and bacterial
and fungal growth.
