Reliable access to clean water is a fundamental welfare requirement for feedlot cattle, and water deprivation or contamination causes significant suffering.
Water deprivation is one of the most severe welfare insults that can occur in intensive livestock systems. Cattle deprived of water show acute distress within hours, developing physiological signs of dehydration that progress to organ failure over days. Even partial restriction through trough contamination or inadequate provision causes chronic low-grade suffering. Water access monitoring is one of the most basic welfare management requirements.
