The farmer is working to improve the health and wellbeing of his or her cows on a daily basis. Dairy companies also hold health and wellbeing in high regard, which is why dairy farms are monitored for this. Next to durability – of which animal health and wellbeing are a part – other aspects such as food safety and quality are also important. Every dairy company therefore has dairy quality system guaranteeing these aspects. In order to supply milk, all farmers have to meet the criteria of the dairy quality system. This system is based on European and Dutch legislation, supplemented with demands from the dairy industry and customers world wide.
