In June 2008 the compulsary nationwide vaccination against BTV-8 (Bluetongue virus serotype 8) was started. After a short time, several owners complained about undesirable effects of the vaccination on fertility and milk quality. Data from 47 dairy farms, regularly supervised by herd health practitioners, were analysed in order to clarify a possible connection between vaccination and fertility. Both vaccinations given each cow for basic immunization were evaluated according to their effects on conception rate and pregnancy. In model calculations the first vaccination had no significant effect on the first service conception rate (FCR), the all service conception rate (ACR) and on the abortion rate. The second vaccination led to a significantly reduced FCR when the cow was inseminated within 20 days of being vaccinated and to a significantly worse ACR when inseminated 10 days before or after vaccination. However, these individually established reductions of the insemination rate had only little influence on overall data.
