Figure 8. Monthly evolution of the simulated effective reproductive ratio R(t) (a and b), and distribution of this R(t) (c and d) when the disease has become enzootic (after 30 years) in standard French beef (a and c, 70 animals) and dairy (b and d, 81 animals) herds.

Solid line: median; dashed: 2.5% and 97.5% percentiles.
