💧 Why water is important:
• Water is the most important nutrient for pigs – they can tolerate a lack of food for several days, but not a lack of water.
• It is necessary for digestion, temperature regulation, blood circulation and milk production in sows.
• Too little water can lead to poor appetite, reduced growth, constipation and, in the worst case, mortality.

💦 Daily water requirement:
The requirement varies according to age, size, feed type and temperature. Here are approximate figures:
Type of pig - Litres of water per day (approx.):
Piglets (up to 20 kg)- 1 to 3 litres
Fattening pigs (20 to 100 kg)- 4 to 10 litres
Pregnant sow - 8 to 15 litres
Growing sow - 15 to 40 litres (depending on litter size and temperature)
Boars (male pigs) - 8 to 15 litres
(If it is warm in the barn, the need can increase by 30–50%)

🚰 Water quality:
• The water should be clean, fresh and without odor or taste.
• Pigs are sensitive to poor water quality. Too high levels of iron, sulfur, bacteria or salt can lead to reduced water intake and health problems.
• pH between 6.5 and 8.5 is recommended.
• Regular cleaning of drinking ni***es and water pipes is important to avoid biofilm and bacteria.

🐽 Watering systems:
• Most barns use ni***es or bowl drinkers.
• Ni**le height should be adjusted according to the size of the pig:
• Piglets: approx. 15–30 cm above the floor
• Finisher pigs: 40–70 cm
• Sows: 70–90 cm
• Water pressure: usually 1–2 bar to ensure enough water without too much spillage.

🧪 Tips:
• Check water flow: Finisher pigs should get at least 1 liter/minute, sows 2 liters/minute.
• Try to observe the pigs – if they drink for a long time without being satisfied, or gather around one point, it may indicate low pressure or poor water quality.
