Water metabolism and intake in goats

Résumé

Water metabolism in goats is reviewed. The main factors affecting water metabolism and free water intake of goats are similar to other ruminants: DM intake (water intake is about 3 times DM intake), composition of feeds and especially their water, salt and mineral contents, taste factors, weight, level of milk production (water required is 1.28 kg/kg of milk) and physiological status (maintenance water intake is 107 for a dry and non-pregnant goat, 140 at mid-pregnancy and 165 g/kg at mid-lactation) and environmental factors. Regulation of water balance is under hormonal and neural control and is also linked to plasma ion concentration. Acute problems occur when goats are unable to maintain water balance or to control body temperature. Goats used to living in desert conditions have an adaptative mechanism of water regulation. Goats seem to be less sensitive to water deprivation than other ruminants and some breeds can adapt quite well to some desert conditions. Good quality water is necessary to reach high levels of production, but in areas where it is scarce, it is necessary to use it efficiently to maximize production
