Distribution of batch sizes as a function of the Euclidean distance travelled for each movement recorded in ScotEID between January 2012 and May 2013. Overall distribution, including all types of departure and destination, is shown in (A). Panels B-D show the distribution of batch sizes where: (B) only movements to slaughter, (C) only movements between producers, and (D) only movements using a haulage company have been considered. Coloured hexagonal binning has been used to illustrate the number of movements across the figure [20].
