Water intake and fluid shifts in horses: effects of hydration status during two exercise tests.
Water intake and fluid shifts in horses: effects of hydration status during two
Brief content of the article:
The authors studied factors affecting the voluntary water intake of horses after an exercise tests . The authors did an incremental test and a 40 minutes constant velocity exercise test. The authors studied the water intake when horses had a (1) normal water intake, (2) after dehydration of 24 hours and (3) after supplying them with 12 L of water before exercise. The following parameters were measured: water intake, plasma protein, osmolallity, plasma sodium concentration, oxygen consumption, plasma lactate, heartrate and plasma aldosterone. The authors concluded that when both an osmotic and hypovolemic thirst stimulus was present, the horses rehydrated more rapidly postexercise. Further, the voluntary water intake of horses was higher from buckets than from the automatic water bowl.
