The incidence and severity of gastric ulceration does not increase in overtrained Standardbred horses.
- Journal Article
Summary
The study investigates whether overtraining increases the risk of gastric ulcers in Standardbred horses. The findings show that experimental overtraining does not raise the incidence of these ulcers in the fed horses and that detraining seems to decrease ulceration.
Objective and Methodology
The goal of the research was to evaluate the impact of overtraining on the incidence of gastric ulceration in performance horses. The researchers focused on how altered hormone levels, behavioral changes, variations in feed intake, and poor performance associated with overtraining could stimulate gastric ulceration.
- The study included 12 Standardbred horses aged 1.5 years, tested on a treadmill for 32 weeks. These weeks were split into four phases: acclimatization, training, intensified training, and detraining.
- During the intensified training period, the horses were randomly assigned to two groups: control (C) and intensified training group (IT).
- At the end of each phase, the horses were subjected to gastroscopy after 12 hours without food and 6 hours without water. The gastroscopy was carried out using a 3.5m video gastroendoscope, and lesion scores were provided for stomach areas, graded 1-4 (from minor to major).
- Statistical calculations were handled with logistic regression.
Results
The study’s results indicated that overtraining does not significantly increase the incidence or severity of gastric ulceration in Standardbred horses.
- Most lesions (70%) appeared around the minor curvature of the stomach.
- The stomach evaluation showed minor changes (grades 1 or 2) throughout. There were no significant differences in gastric ulcer scores between the groups or training periods.
- Interestingly, after the detraining period, no lesions were found in any horse, contrasting with the first (40%), second (30%), and third (30%) periods. This suggests that detraining may reduce gastric ulceration in these horses.
Conclusion
The research concluded that there was no direct link between overtraining and increased gastric ulceration in Standardbred horses. The study’s findings challenge the prevailing belief that the added stress of overtraining usually escalates the potential for gastric ulceration. Moreover, the results highlighted the value of detraining, which seemed to reduce the chance of developing this condition while providing a recovery time, helping to preserve animal health.
