Flow of pig movements as recorded in ScotEID between January 2012 and May 2013. Connectivity within and between Scottish regions through pig movements where: (A) all movements to slaughter have been discarded from the analyses, and (B) only movements to slaughter have been considered. Inserts in A and B show the flow of cross-border movements between Scotland and the rest of Great Britain for non-slaughter movements and movements to slaughter, respectively. Each region in A and B is represented by a pie chart showing the number of producers involved in pig movements as a function of their producer types. The size of the pie chart indicates the total number of producers involved in pig movements either as departure or destination (A), or as departure only (B). Arrows represent the movement, as well as its direction, of pigs. The width of the line indicates the number of batches moved between premises types. Shaded areas in A and B indicate the boundaries of each region considered in this study.
