Adequate water provision is fundamental to pig welfare and productivity, yet water restriction — whether intentional or through inadequate drinker provision — causes significant dehydration, stress, and health impairment in farmed pigs.
Water access is so fundamental that its restriction constitutes one of the most basic welfare failures possible. Yet inadequate water provision — through drinker malfunction, low flow rates, or insufficient drinkers per pen — is a common finding in farm welfare audits. Pigs cannot tell their keepers when they are thirsty, and competition for inadequate drinkers may not be obvious without systematic observation. Daily water intake monitoring through flow meters can detect problems before welfare consequences become severe. Farmers should routinely check drinker function, flow rates, and observe drinking behaviour as part of daily stockmanship routines.
