Water access is the most critical welfare need for all livestock, and water quality problems including contamination, excessive mineral content, and inadequate provision cause serious welfare harm.
Water deprivation is the most rapidly welfare-critical deficiency any livestock animal can experience — animals can survive days without food but only hours without adequate water in warm weather. Water quality problems that cause animals to avoid drinking are functionally equivalent to water deprivation. Daily monitoring of water availability and quality is a minimum welfare management standard for all livestock holdings, and failure to maintain this standard causes preventable suffering.
