Study Finds That Trailering Is A Full-Body Workout For Horses

Many studies have been done on a horse's preferred position while traveling in a horse trailer, but not much is known on how the horse's body reacts while the trailer is in motion.

A research team led by Dr. Robert Colborne created a horse trailer that allowed them to study how a horse's body moves to compensate for trailer movement. They found that a horse's legs play a key role in dampening road vibrations from the trailer floor and helping a horse maintain his balance.

The study trailer had fitted force plates that allowed researchers to measure precisely how a horse moves in response to braking, turning, acceleration, and constant speed horses experience on a typical trailer trip. Two study horses were taken on a 56-mile trip that took 58 minutes to complete; it covered both city and country roads.

They discovered that in total, the horse's bodies moved over 228 and 320 feet vertically during the trip. Though these values seem large, the horse's movement was still less than the vertical movement of the trailer floor. This indicates that horse's use their legs as springs to dampen trailer vibrations.

The horses also adjusted their bodies horizontally to deal with braking. The team found that the horses moved 745 and 797 feet horizontally over the course of the trip. The horses swayed over 11 inches back and forth and side to side during the trip.

It is expected that as horses become more seasoned travelers that their energy expenditure to stay upright and maintain balance would decrease.

Study: Sedation And Whip Use May Lead To Trailering Trouble

Trouble getting a horse on a trailer is common; it often takes time and patience to get a horse to the point where he will load and travel well. However, if the horse needs to get on a trailer and there isn't multiple hours or days to work with him, there are quite a few tricks horse handlers can use, employing everything from feed to brooms to whips to sedation to get him in the trailer.

Nearly 14.5 percent of responders to an Italian study indicated that they had issues loading horses in their care onto trailers within the last two years. The 37-question, online survey was sent to people who were directly involved with the transportation of horses, either for recreational or professional purposes. The survey aimed to identify risk factors for problem behaviors and injuries.

The study team, made up of Drs. Francesca Dai, Martina Zappaterra, Michela Minero, Francesca Bocchini, Christopher Riley and Barbara Padalino, received 148 responses. The questions they asked related to the handler's equine background, vehicles, practices and experience. They were also asked if horses they handled sustained transport injuries within the last two years.

The most common problem behaviors were related to fear and anxiety before loading, including kicking and refusing to get on the trailer, and loss of balance while in the trailer. They discovered that the probability of the horse displaying an issue were:

three times more likely if the driver didn't check the brakes before hauling
five times more likely if the handler was female
five times more likely if the horse handler used a whip at loading
five times more likely if the vehicle wasn't designed for horse protection and if the trailer didn't have shavings as bedding
13 times more likely if the animal was sedated,

Nearly 11.5 percent of respondents said that their horses had injuries directly related to transportation within the last two years. The researchers determined that sedation and coercive equipment, like using whips, were major risk factors for injuries. Though sedation may be helpful to get a horse on a trailer, it can affect the ability of a horse to balance once the trailer is in motion.

Horses were more likely to be injured during travel if the trailer brakes weren't checked before transport, there was no padding on the chest bar and if there were no rubber mats on the floor. Horses that exhibited problem behaviors during loading and transport were more likely to be injured.

The study team concluded that transportation is a risk to the wellbeing of both the horse and the handler, and suggested that more research is needed.

Legislation Banning Double-Decker Trailer Transport For Horses Passes House

Double-decker trailers, the kind used to transport hogs and cattle, are not safe for equine transport: The trailers don't provide enough headroom for the horses to stand comfortably and oftentimes horses in the trailer are injured during transport as they cannot raise their heads to maintain balance.

In 2011, the U.S. Department of Agriculture banned the use of double-decker trailers to transport horses to slaughter, but continued to allow inter-state shipment of horses in these trailers. The Horse Transportation Act (HTSA), part of a legislative infrastructure package called the Moving Forward Act, would ban the shipment of horses in double-decker trailers anywhere in the United States—not just to slaughter.

The act has passed through the House and now must be passed by the Senate before Sept. 30 to become a law. The HTSA is led by Representatives Steve Cohen (D-TN), Peter King (R-NY), Dina Titus (D-NV) and Brian Fitzpatrick (R-PA).
