title: Assessment of strategies to control BVDV spread in a dairy herd using computer simulation.
abstract: The efficiency of a test-and-cull programme to control BVDV spread within a dairy herd was assessed using a stochastic model. A single virus introduction by a non-PI dam carrying a PI foetus was simulated in a typical western-France dairy herd. Herd monitoring in test-and-cull programme enabled us to detect virus spread within 1 year after introduction in 87% of the replications. The test-and-cull programme reduced the length of the virus persistence. The extent of infection was moderately reduced.
