Alleviating surface transit stress on horses

The first published work to study the effect of road transport stress on horses. The study looks at the history of the transport of horses, how the use of motorized transport, increased speed and distances of travel affect the horse's behavior, health, and tow vehicle safety. Human safety and the current dangers of typical loading recommendations into standard horse trailers are outlined.
The New Zealand horse trailer used in the study eliminates or minimizes many of the handling hazards. It is the only horse trailer in the world to meet World Organization for Animal Health (OIE) standards for accommodating horse behavior and human safety. With the publication of Alleviating Surface Transit Stress on Horses, academic and historical interest in the transport of livestock became popular.
Two years before the publication of this work, the Commonwealth Agricultural Bureaux were unable to find any research concerning the transport of horses for their seminal livestock transport report in Animal Regulation Studies. Since Cregier's publication, there are now hundreds of studies from universities all over the world.
Perhaps the most significant were the 1990s Australian studies confirming the original observation of the N.Z. trailer's inventor that horses must be able to lower their heads during transit to clear their respiratory tracts.
