Could adults be used to improve social skills of young horses, Equus caballus?

The study examines how the introduction of adult horses into groups of younger horses could potentially lead to improvements in the young horse’s social behaviors. This suggests that exposure to mature horses can foster better social skills among the younger ones, highlighting the importance of integrated age groups in their upbringing.

Objective & Methodology

• The objective of this study was to understand the potential behavioral changes in young horses when introduced to adult ones. The researchers compared the behavior of 1- and 2-year-old horses kept in homogeneous, same-sex, same-age groups (which is a common domestic practice, but differs from their natural living conditions) to those introduced to two adults of the same sex.
• The horses were observed before, during, and after the introduction of adult horses to capture how their behaviors evolved over the course of this new social structure.

Results

• Findings demonstrated that young horses who were originally reared in homogeneous groups had different behaviors compared to those reared under more socially natural conditions—basically, those that had been exposed to adults.
• Upon the introduction of adults, the young horses began to display new behaviors. Notably, social associations or bonds began to appear, and positive, cooperative social behaviors increased while aggressive, competitive behaviors decreased.

Implications

• The results suggest that the inclusion of adults in young horse groups can positively influence their social behavior—by not only teaching them new ways to interact but also diffusing inter-group tensions. They highlight the value of replicating more natural social conditions where different age groups interact with each other. This has significant implications for horse rearing practices in domestic settings, challenging the common practice of same-age grouping.
• Despite these revealing findings, the study notes that more research needs to be done to understand the full breadth of adult influences on young horses’ behavior and the best practices for introducing adults into these groups.
