Prevalence of gastric ulcers in endurance horses–a preliminary report.

The research found that 67% of endurance horses develop gastric ulcers, which is similar to the rate seen in performance horses. The abnormalities present in these horses were usually not as severe compared to those in thoroughbred race horses.

Methodology

The researchers performed endoscopic checks on endurance horses at the completion of either a 50 or 80 km endurance ride. This allowed them to check for gastric ulcers and other conditions. This method was chosen because it allows for a comprehensive and definitive look at the inside of a horse’s stomach.

• Endoscopy: A technique that involves inserting a long, flexible tube (endoscope) down the throat and into the stomach. This enabled the researchers to directly observe the internal surfaces of the stomach and identify any gastric ulceration.

Findings

Through the use of endoscopy, they discovered some key findings:

• Gastric Ulcers: 67% of the endurance horses were found to have gastric ulcers. The squamous region of the stomach was affected in 57% of the horses.
• Active Bleeding: Active bleeding of the glandular mucosa, or the inner lining of the stomach, was seen in 27% of the horses. This points to a severe form of gastric ulceration and is a cause for concern.
• Lesions on Glandular Mucosa:In 10% of the horses, lesions were found only on the glandular mucosa. This implies that the area is particularly vulnerable in endurance horses.

Comparison with Other Horses

The researchers compared their findings with data from previous studies on different types of horses.

• Similarity with Performance Horses: They found that the prevalence of gastric ulceration in endurance horses was similar to the rates observed in performance horses. This suggests that intense physical exercise may be a contributing factor to the development of gastric ulcers in horses.
• Difference from Thoroughbred Race Horses: The study revealed that the severity of the gastric ulceration in endurance horses was less than what has been reported in thoroughbred race horses in active training. This could be due to differences in the intensity and type of training among different breeds of horses.

Implications of Research

As owner awareness and further investigation of the high incidence of gastric ulcers and active bleeding from the glandular mucosa in endurance horses is necessary, it is crucial to monitor and care for their horses’ health. Special attention should be given to their diet, exercise regime, and overall well-being to prevent such conditions.
