The relationship between the basic reproduction number and infected dairy cows while and , where (2) and (3) of Theorem 9 holds. The common values of (a) and (b) used for the parameters are as follows: , , , , , , , and . The different values of (a) and (b) are (a) , (b) . There is a forward bifurcation at in (a). The bifurcation at in (b) is still forward.
