Qualitative numerical simulation results of different scenarios with respect to infected cattle.

Numerical values and definitions are in the Supporting Information. We define that if there is at least one cattle infected, then the farm is infected. represents the number of infected farms. represents the cumulative number of infected cattle throughout simulation. is the total number of infected cattle when the number of infected cattle farms is maximum. denotes the time to peak number of infected farms, that is, the time it takes from the first day to the day on which the largest number of infected farms appears as shown in Fig. 3. denotes epidemic duration, defined as the number of days with more than infected cattle farms. The average number of infected farms in each day is in the range of , the average cumulative number of infected cattle during simulation is within the range , and the average time to peak is within .
