Water intake by livestock is related to species, breed, animal size, age, diet, animal activity, temperature and physiological status of animals . Direct water use by cattle may increase by 13% for a temperature increase of 2.7℃ in a subtropical region . Changes in water availability may arise because of decreased supply or increased competition from other sectors. Availability changes may be accompanied by shifts in water quality, such as increased levels of microorganisms and algae, that can negatively affect livestock health . In arid lands, projected decreases in water availability will severely compromise reproductive performance and productivity in sheep . In higher- input livestock systems, water costs may increase substantially owing to increased competition for water .
