The Effects of Head Position on Stress Levels in Horses
Horses are used in a variety of equestrian disciplines, many of which require a horse to assume a specific head position. These positions may stress the horse by altering its respiratory efficiency or making the horse anxious due to being overly restricted. To investigate this, a randomized Latin Square experimental design was used to evaluate three different head positions. Treatments included: natural carriage (control), vertical, and hyperflexed head positions. Head position angle was determined using the Equla Vert tool and maintained with side reins and a surcingle. Resting heart rate was recorded. The horse was lunged at a trot for ten minutes, and heart rate data and videos were collected. Blood was drawn prior to, and immediately after lunging. Videos were analyzed and assigned a numerical score based on the Equine Grimace Scale. Data will be analyzed to evaluate the stress response to the different head positions.
