The dairy supply chain turns raw cow milk collected on French farms into a range of products — drinking milk, cream, butter, cheese, yoghurts and milk desserts, powders — each of which draws on a different fraction of the milk's matter. Following this chain therefore means following not one quantity but several: the raw volume collected, and the fat and protein it contains, which processing distributes among the products.
Scope. Cow milk, whole of France, from farm collection through to dairy products and their end uses, including foreign trade.
Units. Milk is the only SOCLE supply chain counted in four simultaneous units: kt PB (raw weight, shown by default), kt MU, kt MG (fat) and kt MP (protein). The unit banner above the diagram switches between them and the widths are recomputed.
Campaigns. Three campaigns are modelled: 2015, 2019 and 2023 (pick the year on the timeline below the diagram).
Two pages make up this supply chain: Results, the diagram of the whole chain; Method and sources, the diagrams that say where the data comes from and how much confidence to place in it.
