All pigs must have ready access to clean good quality water.
The Code of Recommendations for Livestock and The Welfare of Farmed Animals (England) Regulations 2007,state that " All pigs over two weeks of age must have continuous access to a sufficient quantity of fresh drinking water ".

As with people, water for pigs is essential for nearly all body functions, growth, food adsorption, temperature regulation and excretion of waste. Newborn pigs are over 80% water! whereas a finisher pig is about 55% water. Severe water deprivation can result in death.  The effects of  even minor dehydration are reduced feed intake leading to lower daily weight gain. Poor feed conversion leads to reduced milk production and lower weaning weights. So it is sensible to check the water supply when performance problems are being investigated as well as the feed.
Action for drinking water
  • Have more than one drinker available per pen, if one fails the other is backup.
  • Check they are working daily.
  • Install drinkers at the correct height - see Chart 2- for the age of the pigs remember pigs grow, so have drinkers at different heights. An adjustable height drinker is very useful.
  • Check flow rates of nipple drinkers. Water pressure,pipe diameter and pipe length all affect water flow rate. The drinker furthest from the tank may have a completely different flow rate to the drinker nearest to it.
  • To check the flow rate, time how long it takes to fill a jug to the 1 litre mark- then compare this to Chart 1.
  • Wet and Dry feeder systems required that an additional nipple drinker be provided per 10 pigs.
  • Pipe Line Wet Feed systems require that an additional drinker be provided per 30 pigs.

A note  on the Freedom foods drinker requirements guidance:
One drinking space is the space required by a pig to drink.
Bowls that allow space for two pigs to drink together can be counted as two spaces, however if the pigs are small to start with, it is likely the bowl will become a single space as the pigs get bigger.
these instructions are as we understand them, please get guidance direct from freedom foods as their interpretation my vary.
