Oral Electrolyte and Water Supplementation in Horses

Area of Science:

• Equine Sports Medicine
• Animal Physiology
• Nutritional Science

Background:

• Horses lose significant water and electrolytes through prolonged sweating.
• Dehydration is a common issue in equine disciplines, impacting wellness and performance.
• Exercise or transport exceeding one hour can lead to substantial dehydration.

Purpose of the Study:

• To highlight the importance of oral electrolyte supplementation for horses.
• To explain the physiological mechanisms of water and electrolyte absorption.
• To provide guidelines for effective electrolyte replacement strategies.

Main Methods:

• The abstract discusses the physiological processes of absorption and utilization of water and electrolytes.
• It emphasizes the role of the stomach and small intestine as reservoirs for consumed solutions.
• It highlights the importance of supplement composition and palatability.

Main Results:

• Oral electrolyte supplementation effectively replaces losses from sweating.
• The small intestine is the primary site for rapid absorption of ions and water.
• Proper osmolality of supplements is key for gastric emptying and intestinal absorption.

Conclusions:

• Maintaining hydration and electrolyte balance is vital for equine health and performance.
• Effective electrolyte supplements must match ion losses and be consumed with adequate water.
• Training horses to voluntarily consume electrolyte solutions is recommended for optimal results.
