Water is considered an essential nutrient. While an animal can survive for a week or so without food, water deprivation can only be tolerated for a few days. Water is important for a variety of bodily functions that include but are not limited to nutrient transportation, body temperature regulation, lubrication of joints and organs, enzymatic/chemical processes including those related to feed digestion. A large number of factors can influence water usage in the bird’s body and include environm...ental temperature, relative humidity, health status of the bird (especially intestinal health), diet formulation, presence or absence of feed, and even genetics. Because water consumption plays so many roles in the health and performance of a bird much can be learned by simply monitoring daily water consumption.
