Influence of an active stable system on the behavior and body condition of Icelandic horses.

This study explores the impact of an active group housing system on the behavior and health of Icelandic horses, as an alternative to conventional individual stabling. The research found that the active stable system significantly increased the horses’ levels of activity and rest, and showed no negative effects on their body weights or general body condition.

Study Design and Methodology

• The study observed eight Icelandic horses that were kept in an active stable system. The team closely recorded their behavior and how they spent their time.
• The researchers used Activity, Lying, Temperature (ALT) detection pedometers to track the movement and resting behavior of the horses.
• The study also examined the effect of an automatic concentrate feeding station (CFS) on the horses’ behavior. During the first phase, the horses were manually fed, and in the second phase, they were fed using the CFS.
• Further behavioral observations and social hierarchy determinations were made either directly or through video surveillance.
• The horses’ physical conditions were also monitored through body weight measurements and body condition scoring (BCS).

Findings of the Study

• With the introduction of the CFS in the second phase, there was a significant increase in both the horses’ activity (P < 0.001) and lying-down time (P = 0.003).
• There was no significant difference in body weight during the first phase without CFS (P = 0.884) or during the second with CFS (P = 0.540).
• The body condition scores of the horses remained at a very good level throughout both trial periods.
• The horses in the active stable system displayed a low level of aggression, a clear social hierarchy, and behavioral synchronization, indicating a healthy social environment.

Implications of the Study

• The study suggests that group housing in accordance to the active stable system is a welfare-oriented method of horse management. This type of system better aligns with horses’ natural needs and behaviors than typical individual stables.
• The use of an active stable system did not negatively impact the horses’ body weight or overall body condition, suggesting it can be a sustainable housing alternative.
• The behavioral benefits observed, such as low levels of aggression and established social hierarchies, indicate that group housing allows for healthier social interactions among horses.
• While the study was conducted among Icelandic horses, the findings could be applicable to horses in other regions, offering a more humane option across the equine industry.
