Dually investigated: The effect of a pressure headcollar on the behaviour, discomfort and stress of trained horses

Abstract

The Dually™ is a control headcollar designed to improve equine behaviour during handling challenges by applying greater pressure than a standard headcollar. Previous research indicated it did not improve compliance in naïve horses but did result in higher Horse Grimace Scale scores (HGS) indicative of discomfort. suggesting that behaviour becomes less desirable during early Dually training. Yet, stress and HGS indicators were not higher in the Dually compared to Control during testing. Results suggest the Dually has a negative effect on behaviour but not on stress or discomfort during short handling challenges. Further research is warranted to determine the long-term effect of Dually experience on behaviour and welfare.

Use of Infrared Thermography to Assess Body Temperature as a Physiological Stress Indicator in Horses during Ridden and Lunging Sessions

“…Personality is the result of the effects of life experiences and environment on temperament [ 5 ], while temperament is defined as stable behavioral tendencies present in early life [ 6 ], although the terms have been used interchangeably. As with humans, personality affects the response to stimuli, namely during handling [ 7 , 8 , 9 , 10 ], horse–object/investigative interaction [ 11 , 12 ] and social interaction [ 8 ]. A generalized personality type can be attributed based on direct observation, measurement of behavioral and physiological markers or a combination [ 13 ].…”

Identification of Thoroughbred Racehorse Welfare Issues by Industry Stakeholders

“…For example, by questionnaires of owners of non-racing horses and veterinary examinations [ 9 ], or by observation of health and behaviour parameters [ 10 ]. Particular promise has been shown with infrared thermography, especially of the eye [ 11 ], and the use of a pressure head collar [ 12 ]. With TBRs, different techniques are required to include their welfare on the racetrack compared with Arabs, which is affected by their locomotory, cardiovascular, and respiratory soundness [ 13 ].…”
