Hair cortisol concentration is inversely related to the severity of equine squamous gastric disease.

This research investigates stress in horses in relation to equine squamous gastric disease (ESGD), finding that lower hair cortisol levels correlate with more severe ESGD symptoms.

Objectives and Methods

• The main aim of this study was to explore the relationship between hair cortisol concentration (HCC) – a marker of medium to long-term stress – and the occurrence and severity of ESGD in horses.
• The researchers collected hair samples from 25 horses and performed gastroscopies on them to identify the presence and evaluate the severity of ESGD.

Findings

• The findings revealed that horses with ESGD had noticeably lower HCC, indicating an inverse relationship between stress levels and ESGD severity.
• Interestingly, the study found that mares demonstrated lower HCC compared to geldings and also showed a higher prevalence of ESGD.
• The researchers found no significant impact of the age of the horses on these outcomes.

Conclusion

• The study successfully identified a clear association between lower HCC and increased severity of ESGD, suggesting a potential link between lower stress levels and ESGD severity.
• However, the researchers concluded the study by suggesting that more detailed research is necessary to fully understand the significance and implications of this correlation.

Implications

• This research may hold important implications for understanding how stress impacts the health and well-being of horses, specifically in relation to ESGD.
• It could potentially influence future approaches to ESGD prevention and treatment, emphasizing the importance of stress management in equine health care.
