Few studies have investigated the environmental conditions under which horses
travel, and consequently little is known about the thermal environment within horse trailers. Animal
well-being may be compromised by exposure to extreme temperatures, or air contaminants leading
to complications such as dehydration, heat stress, or respiratory infection as a consequence of
insufficient ventilation. This study was undertaken to estimate ventilation rates within an empty horse
trailer during transport. Estimation of ventilation rates were made by measuring the decay time of a
known quantity of carbon dioxide (CO2) at different locations within the trailer. Ventilation rates
through a horse trailer were evaluated as functions of vehicle speed and opening sizes.
