Water plays a key role in milk production, control of body temperature and many other body functions in dairy cattle. While feed and ration management are generally monitored in detail, water intake, availability and quality are often overlooked. Cows consume around 4-4.5 litres of water per kg milk production and drinking water can satisfy 80-90% of a dairy cow’s total water needs. Generally, cows only drink in short bouts (7-12 times a day) during which they consume a total of between 10 to 20 litres of water, In particular cows prefer to drink after milking and during feeding. This behavior is clearly seen in herds, where cows will go to drink after visiting the robot.
