Farmed Pig Water Access and Drinking Behaviour

Adequate water provision is fundamental to pig health and welfare.

Key Facts

Pigs require 5-10 litres of water per day depending on size and ambient temperature
Water restriction causes acute stress and is a serious welfare breach
Nipple drinker design and flow rate affect ease of drinking significantly
Pigs prefer to drink and eat simultaneously, often requiring co-located water and feed

Welfare Considerations

Pigs with inadequate water access experience acute distress from thirst, reduced feed intake, and increased aggression as they compete for limited water. Even short periods of water deprivation cause significant welfare harm in hot conditions. Water provision that is technically available but practically inaccessible — through faulty drinkers, inadequate flow rates, or insufficient numbers — is a common but preventable welfare failure.

What You Can Do

Support mandatory water access monitoring requirements in pig welfare standards
Advocate for minimum water provision requirements including flow rate standards
Choose assurance-scheme pork that verifies water provision adequacy
