Water Quality and Livestock Welfare

Access to clean, fresh water is fundamental to livestock welfare, yet water quality is frequently substandard on farms and in transport.

Key Facts

Cattle require 30-50 litres of water per day for maintenance and production
Water deprivation for 24 hours reduces milk production by up to 40% in dairy cows
Water contamination from algae, bacteria, or excess minerals causes illness and reduced intake
UK welfare regulations require water to be accessible and of adequate quality
Dehydration during transport is a leading contributor to heat stress mortality

Welfare Considerations

Water deprivation causes acute suffering through thirst and physiological dehydration effects including increased heart rate, reduced blood volume, and elevated cortisol. Livestock that voluntarily reduce water intake due to poor water quality are chronically dehydrated and stressed. Transport without adequate water provision in warm conditions causes suffering that can be fatal. Water quality is a basic welfare requirement that is insufficiently monitored.

What You Can Do

Advocate for mandatory water quality testing on farms
Support welfare inspections that specifically assess water availability and quality
Back transport regulations that mandate water provision at specified intervals
Choose products from farms where water quality is monitored and documented
Report suspected livestock water deprivation to animal welfare authorities
