Effect of ‘tongue tie’ use on racing performance of thoroughbreds in the United Kingdom.

Abstract: There is contradictory published evidence on the potential efficacy of 'tongue ties' (TTs) for treatment of intermittent dorsal displacement of the soft palate (DDSP) in racehorses. Objective: To evaluate the effect of TTs on racing performance in Thoroughbred racehorses in the U.K. using a retrospective cohort study. Methods: Data on individual horses' lifetime racing performance and TT use were retrieved from the Racing Post Online Database. Exposed cases were horses that ran with a TT in randomly chosen race meetings on one of 60 randomly chosen dates from 2001-2003. Unexposed (control) horses were matched to each exposed horse. Various measures of racing performance were analysed both within and between exposed and unexposed groups. Subsets of exposed horses that ran for 3 or 5 consecutive starts wearing TTs and their matched controls were analysed separately to examine the effect of repeated TT use. Results: The inclusion criteria were fulfilled by 108 horses. The odds ratio for 'improvement' in race earnings between exposed and unexposed horses was 1.85 for horses that ran at least once with a TT, and 3.60 and 4.24, respectively, for horses that ran in 3 or 5 consecutive races wearing a TT. After instigation of TT use, horses that ran in 3 or 5 consecutive races wearing a TT had a significant increase in earnings when they ran wearing a TT compared to their pre-TT races. Conclusions: The use of a TT appears to have a beneficial effect on racing performance in a selected population of Thoroughbred racehorses.

The study investigates the impact of using ‘tongue ties‘ (TTs) on the performance and earnings of Thoroughbred racehorses in the U.K. The findings suggest that TT use is linked to improved racing performance and increased race winnings.

Research Aim and Methods

  • This study sought to assess the influence of TTs on the racing performance of Thoroughbred racehorses by conducting a retrospective cohort study.
  • Individual horses’ racing performance data and TT usage were obtained from the Racing Post Online Database.
  • ‘Exposed’ horses that raced with a TT at randomly selected race meetings between 2001 and 2003 were considered as cases. Unexposed horses, which did not use a TT, were used as corresponding controls.
  • Several indicators of racing performance were evaluated within and between the TT-exposed and TT-unexposed groups.
  • The researchers carried out additional analysis on subsets of TT-exposed horses that used a TT for 3 or 5 consecutive races to investigate the impact of repeated TT use.

Findings

  • A total of 108 horses met the inclusion criteria for this study.
  • The odds ratio for ‘improvement’ in race earnings between TT-using and non-TT-using horses was 1.85 for horses that raced at least once with a TT.
  • For horses that ran in 3 or 5 consecutive races using a TT, the odds ratio for improvement in race earnings was 3.60 and 4.24, respectively.
  • Horses that raced in 3 or 5 consecutive races using a TT demonstrated a significant increase in earnings when wearing a TT compared to their earnings before TT use.

Conclusions

  • The findings implied that TT usage may enhance racing performance in Thoroughbred racehorses.
  • Notably, consistent use of a TT in consecutive races seemed to result in a significant rise in race earnings.
