Temperament in preweanling horses: development of reactions to humans and novelty, and startle responses.

The research article focuses on investigating the development and consistency of three temperament characteristics in young foals: their reactions to humans, novel situations, and sudden events. These traits were studied in foals of different ages to observe any changes over time and across situations.

Research Process

• The researchers conducted a comparative study involving three independent groups of animals, each group containing 27 foals. The three groups were of different ages – 3 weeks, 12 weeks, and 24 weeks – and were tested for their reactions towards humans and novel objects.
• In a separate longitudinal study, 48 foals were tested at four different time intervals: 3, 6, 12, and 24 weeks of age. This allowed the researchers to observe the evolution of their reactions over time.

Research Findings

• The researchers observed that 3-week-old foals almost lacked any avoidance behaviour towards humans or interest in new objects. However, these behaviours became progressively more evident as the foals grew older, particularly in the groups that were 12 weeks and 24 weeks old.
• In the longitudinal study, the researchers found that the foals’ reactions developed over time, with no immediate stability across different situations or over time. However, once a foal displayed a behavioural reaction at a given age, this behavior tended to be repeated in subsequent situations, suggesting a form of behavioural consistency over time.

Implications

• The findings from this study could be quite significant as they help understand the behaviour patterns in horses, especially the young ones. This understanding has implications for training, socialization, and potentially improving the welfare of horses.
• By shedding light on the developmental patterns of temperament traits, the research could also contribute to genetic and neuroscientific studies about equine behaviour and temperament.
