Simmental cows have a white head, white legs, a white belly and a white bushy tail. The rest of their coat is covered in patches that range in colour from light gold to reddish brown. Grass is hard to digest. That’s why cows chew an average of 50 times per minute – a total of 30,000 times per day. Even if we humans really make an effort, we generally don’t chew a morsel of food more than 30 times. Cows produce over 150 litres of saliva per day as a result. This makes them very thirsty, so they also drink a lot of water: up to 180 litres per day. This is equivalent to a large bathtub filled to the top. If they are very thirsty, they can even drink 25 litres per minute.
