Environmental conditions in equine indoor arenas: A descriptive study

Area of Science:

• Environmental Science
• Agricultural Engineering
• Equine Science

Background:

• Indoor arenas often lack consistent ventilation, leading to unpredictable environmental conditions.
• Sporadic occupancy by horses and humans complicates the management of temperature, moisture, and airflow.
• Understanding these microclimates is crucial for animal welfare and facility maintenance.

Purpose of the Study:

• To characterize the interior environmental conditions of indoor arenas.
• To assess temporal variations in temperature, humidity, and airflow.
• To identify potential environmental challenges impacting horse and human health.

Main Methods:

• Conducted environmental monitoring at 15 indoor arenas near Lexington, KY.
• Collected data on dry bulb temperature, relative humidity, dew point, air speed, and solar radiation for 7 days in winter and summer.
• Utilized HOBO RX3000 Remote Monitoring Stations with specialized sensors.

Main Results:

• Significant seasonal and diurnal patterns were observed across all measured environmental parameters.
• Relative humidity and dew point indicated potential moisture issues in many arenas.
• Air speeds were consistently below the recommended threshold for livestock facilities, suggesting poor air circulation.

Conclusions:

• Indoor arena environments exhibit notable temporal variability influenced by seasons and daily cycles.
• Elevated moisture levels are a concern, potentially affecting health and infrastructure.
• The study highlights the need for improved environmental monitoring and arena design to mitigate risks.
