摘要: Objective—To determine the baseline costs of bovine leukemia virus (BLV) infection, including clinical disease and subclinical in a dairy herd representative mid-Atlantic region compare these with cost test-and-manage BLV control program. Design—Stochastic spreadsheet model. Sample Population—A commercial Holstein 100 milking cows. Procedures—A model was developed. The overall infection included (ie, lymphosarcoma [LS]) effects on milk production premature culling. Model input values distributions were designed to reflect economic conditions region. Relative calculated for prevalences 20, 50, 80%. Results—Estimated mean producer per case LS $412; 50% prevalence annual incidence 0.66. Mean infec...
