Social Isolation of Horses vs. Support Provided by a Human

Area of Science:

• Equine behavior and welfare
• Animal physiology

Background:

• Horses possess a strong herd instinct.
• Human social support's efficacy during equine isolation is not well-established.

Purpose of the Study:

• To evaluate equine behavior and heart rate responses to different forms of human support during social isolation.
• To determine if human contact can mitigate stress in isolated horses.

Main Methods:

• 12 warmblood horses (mares and geldings) underwent isolation tests.
• Behavioral observations and heart rate monitoring (Polar H9, Polar Ignite2) were employed.
• Four test conditions included: presence of conspecifics, isolation, and isolation with tactile, vocal, or combined human support.

Main Results:

• Human support (tactile, vocal, or combined) showed limited significant effects on horse behavior and heart rate during isolation.
• Geldings exhibited more favorable responses to human support compared to mares.
• Vocal support appeared to yield the most positive effects, especially in emotionally balanced horses.

Conclusions:

• Human social support offers minimal mitigation of stress during short-term equine herd isolation.
• Individual differences, such as sex (geldings vs. mares) and emotional stability, influence horse responses to human interaction.
• Vocal support may be the most effective form of human intervention for isolated horses.
