Hospital-based study of dental pathology and faecal particle size distribution in horses with large colon impaction.

This study aimed to investigate whether there’s a correlation between dental pathology and large colon impaction in horses, as well as examining the relationship between faecal particle size distribution and dental health. However, no significant association was found between these factors.

Study Overview

• The study was a prospective investigation involving a total of 111 horses, 39 of which had large colon impaction (a common and painful digestive disorder in horses), and 72 served as the control group.

Methodology

• Each horse was assigned an oral pathology score (OPscore) and a periodontal disease index (PDI) to assess their dental health.
• Faecal samples were collected and analyzed to estimate the faecal particle size and its distribution. This was done to determine if there is a relationship between dental health and digestion, as horses with poor dental health might not chew their food sufficiently, leading to larger faecal particles.

Findings

• The results showed that horses with large colon impaction were not more severely affected by dental disease than control horses, as assessed by both the OPscore and PDI.
• The analysis of faecal samples revealed that the particle size was significantly larger in the control group than in the group with large colon impaction.
• No significant relationship was found between faecal particle size and either OPscore or PDI in either group of horses.
• In the group of horses with large colon impaction, a slight increase in faecal particle size was observed as the PDI increased, suggesting some association between dental health and digestion in these horses.

Conclusion

• Dental health does not seem to be a significant factor in the development of large colon impaction in horses. Furthermore, while the presence of larger faecal particles is associated with better dental health in control horses, this relationship isn’t evident in those with large colon impaction.
• These findings suggest that additional factors, aside from dental health, may be causing large colon impaction in horses. Future studies might focus on identifying these components for better prevention and treatment strategies.
