Adequate clean water provision is one of the most basic welfare requirements for cattle. Deficiencies in water access cause rapid welfare deterioration and reduced production.
Water deprivation in cattle causes rapid deterioration — feed intake falls within hours of restricted water access, and milk yield in dairy cows drops significantly within 24 hours. Competition for limited trough space means subordinate animals in the social hierarchy may be consistently underserved. Regular trough cleaning, adequate provision relative to group size, and frost protection in winter are essential welfare management elements.
