In Japan, the number of cows per dairy farm is still so small that milk has to be collected at collecting stations first, and shipped to a factory. In the case of a large milk shed in Fukuoka Prefecture, the hauling and shipping cost was calculated through investigation. It was considerably high. By an econometric method, it was made clear how the cost could be minimized by decreasing the number of and enlarging the scale of collecting stations under the can- and the bulk-hauling systems.
