Water Provision for Pigs: Welfare Essentials 2026

Adequate water provision is a fundamental welfare requirement for pigs, with insufficient access causing significant distress and health problems.

Key Facts

Water is the most essential nutrient for pigs - they need 2-10 litres per day depending on size and stage
Pigs denied water for even short periods show increased aggression, stress, and welfare compromise
Drinking nipple or bowl design, water pressure, and flow rate all affect whether pigs can drink adequately
Water-restricted sows in gestation develop stereotypies and significant welfare compromise
UK welfare regulations require pigs to have permanent access to sufficient clean water

Welfare Considerations

Water welfare in pig production is frequently overlooked compared to feed management, but inadequate water access causes rapid and severe welfare compromise. Blocked nipple drinkers, low flow rates, and insufficient drinking points per pig can mean that subordinate animals fail to drink enough even when water is technically available. Lactating sows have particularly high water requirements and suffer rapid welfare and production decline if water access is insufficient. Regular monitoring of drinking behaviour and water flow, along with weekly checking of all drinker systems, is an essential welfare management practice that is insufficiently emphasised in some systems.

What You Can Do

Ensure all pig drinking points are checked daily for blockage and adequate flow
Provide sufficient drinking points to allow all pigs access without excessive competition
Monitor water consumption as an early indicator of health problems and welfare decline
Advocate for water provision as a key welfare inspection criterion in pig farm assurance
