Stochastic bio-economic model of bovine intramammary infection

摘要: Abstract Although the dynamics of transmission play an important role in occurrence intramammary infection (IMI), they have not been considered previous models used to estimate cost IMI. The bio-economic model described includes within-herd pathogen-specific simulated Staphylococcus aureus , Streptococcus uberis dysgalactiae and Escherichia coli IMI stochastically estimated these a herd 100 dairy cows situation where quota is applied milk production. A Reed–Frost was for S. Greenwood E. Economic analysis conducted per pathogen clinical subclinical parameters were based on literature deemed credible valid. Median annual incidence all pathogens varied considerably.
