Pawing by standardbred racehorses: frequency and patterns.

This research studied the prevalence and pattern of pawing behavior in Standardbred racehorses, and its connection with time of day, particularly before and after training. The researchers found that the majority of the horses, especially after training, demonstrated pawing behavior. They also noted that the frequency of pawing in the afternoon was significantly greater than in the morning, and decreased on Sunday afternoons when no training occurred.

Objective and Methodology

• The study aimed to understand the prevalence of pawing behavior in Standardbred racehorses and identify any correlation between the frequency of pawing and specific times of the day. In particular, the researchers sought to figure out if the behavior was more prevalent before or after training sessions.
• The researchers observed 41 Standardbred racehorses using instantaneous scan sampling done twice daily, once in the morning before training and once in the afternoon post-training.

Key Findings

• Of the 41 horses observed, twenty-four, or 58.5%, displayed pawing behavior at least once. The median count of pawing occurrences was seven, with an interquartile range of 2-15. This means that for over half of the horses, pawing was a typically observed behavior.
• The frequency of pawing was found to be greater in the afternoon after training, with a median count of four observations and an interquartile range of 1-11. This accounted for 11.2% of all observations.
• Before training in the mornings, there were fewer pawing observations, with a median count of three and a slightly lower interquartile range of 0-3.25. Pawing during the pre-training period accounted for 9.1% of total observations.
• The data revealed a statistically significant increase in the frequency of pawing behavior in the afternoon (P=0.0005). This suggests that the act of training might induce, incentivize, or somehow relate to pawing behavior.
• Interestingly, pawing behavior specifically reduced on Sunday afternoons when horses had not undergone training. This further supports the inferred link between pawing and training or exercise.
• The finding suggests that in addition to being an exercise-related response, pawing might also be a signal of discomfort in the horses.

Implications

• The findings from this study offer valuable insights into the behavioral patterns of Standardbred racehorses, particularly in relation to their training regimes.
• These insights could also be of use to equine veterinarians or horse trainers in understanding discomfort signals in horses and might aid in refining training schedules or processes to enhance the wellbeing of the horses.
