Over the years, additional cooperative dairies were founded. After The Second World War, there were 1,650 dairies in Denmark and the number continued to grow until the 1960s when the idea of creating nationwide dairies was suggested. From then on, mergers and acquisitions among dairies was part of the daily life in both Denmark and Sweden.
In 2000, the Danish MD Foods and the Swedish Arla economist Förening decided to merge. This was the first large cross-national merger in the Nordic dairy industry.
