Economic impact of BVDV infection in dairies.

摘要

The detrimental effects of bovine virus diarrhoea virus (BVDV) infections include reduced milk production, reduced reproductive performance, growth retardation, increased occurrence of other diseases, unthriftiness, early culling and increased mortality among young stock. These losses have been documented in several case descriptions and to some extent quantified in epidemiological studies. The detrimental effects together with information on population structure, incidence of infection and monetary value of production losses have been included in different models for estimating economic losses and benefits of different control strategies.This paper reviews different studies and methods for estimating economic losses and the economic effect of control strategies on both the local herd level and the national herd level. The estimated losses in individual herd outbreaks have varied from a few thousand up to
