  1. Parameters obtained for the best fit when optimizing on each farm separately (first five rows) and when optimizing using only one set of parameters for all farms (last row). α is the coefficient of the indirect transmission, β is the coefficient of the cow-to-cow infection, and δ is the constant contribution to force of infection. Parameters µ and σ are the average and standard deviation of the latent period, and γ is the power of the bacterial load in the force of infection.
