D(+)-xylose absorption test in the horse. A clinical study

Area of Science:

• Veterinary Medicine
• Equine Health
• Gastrointestinal Physiology

Background:

• The D-xylose absorption test is a common diagnostic method for evaluating intestinal function.
• Understanding equine gastrointestinal health is crucial for overall horse well-being.

Purpose of the Study:

• To evaluate the efficacy of the D-xylose absorption test in assessing intestinal function in horses.
• To determine the correlation between D-xylose absorption patterns and gastrointestinal health in horses.

Main Methods:

• Twenty-five horses were administered 1 gram of D-xylose per kilogram of body weight orally.
• Horses were categorized into four groups based on their D-xylose absorption curve patterns.
• The impact of sodium chloride administration on D-xylose absorption was investigated.

Main Results:

• Horses were classified into normal (11), flat (8), and intermediary (7) absorption curve groups.
• Sodium chloride administration did not enhance D-xylose absorption.
• A significant decrease in D-xylose absorption was noted in 73% of horses exhibiting gastrointestinal disease signs.

Conclusions:

• The D-xylose absorption test is a valuable diagnostic tool for evaluating intestinal function in horses.
• Decreased D-xylose absorption is indicative of potential gastrointestinal issues in equine patients.
