Conservative treatment for thoroughbred racehorses with intermittent dorsal displacement of the soft palate.

This research paper examines the effectiveness of conservative treatment methods such as rest, fitness improvement, and use of a tongue tie for thoroughbred racehorses affected by dorsal displacement of the soft palate, comparing their race performance before and after treatment. The results indicate a statistically significant improvement in earnings among treated horses, but not in the control group.

Objective and Methodology

• The objective of the study was to explore the effectiveness of conservative methods for the management of intermittent Dorsal Displacement of the Soft Palate (DDSP) in Thoroughbred racehorses. This condition impairs the horse’s performance, as the displacement blocks the airflow to the lungs during strenuous activity.
• The researchers used race records for 31 horses treated for DDSP conservative treatments and compared them with a control group consisting of 62 matched horses not diagnosed with this condition.

Conservative Treatment

• The researchers applied conservative treatment strategies such as rest, fitness improvement regimes, and use of a tongue tie. A tongue tie is a band that loops around the horse’s tongue and lower jaw to prevent the tongue from sliding back into the throat, thus helping mitigate DDSP.
• The impact of these treatments was determined by tracking and comparing the horse’s race performance based on the prize money won for three races before and post-diagnosis.

Findings

• The results revealed that conservative treatment had a significant effect on the race performance of the horses diagnosed with DDSP. A total of 19 or 61% of the treated horses displayed higher earnings after receiving the treatments.
• In comparison, 27 or approximately 43.5% of the total 62 control horses showed increased race earnings, but this increase was not statistically significant.
• Overall, it was found that the conservative treatment led to a significant rise in race earnings of horses with DDSP (P=0.049), while no such significant enhancement was observed in the control group’s earnings.

Conclusions

• This research establishes the effectiveness of conservative treatment methods including rest, fitness improvement, and the use of a tongue tie in managing DDSP in thoroughbred racehorses.
• The study’s findings could have significant practical implications for horse trainers, veterinarians, and owners, possibly improving the performance and wellbeing of horses afflicted by DDSP.
