Abstract

The aim ofthis thesis was to study factors affecting water intake and fluid regulation in the horse, both at rest and in connection with exercise. Exercising horses sometimes show little inclination to drink despite extensive fluid losses and free access to drinking water. The results from this thesis confirm that a lack of an osmotic thirst stimulus (i.e. increase in plasma sodium concentration) reduces the post-exercise voluntary water intake in the horse. The water supply method had a great influence on the daily water intake. The daily intake was about 40% higher when horses were drinking from buckets than from an automatic water bowl (float valve, 3 L/min). In a two-choice preference test all horses showed a strong preference for buckets compared to an automatic bowl (pressure valve, 8 L/min). Different strategies for voluntary rehydration during endurance exercise were tested in a field trial. It was found that horses offered a saline solution to drink (9g NaCl/L) had the highest fluid intake and regained 84% of their body weight losses (
