A report is given on the development of the subsidies granted by the "Niedersachsische Tierseuchenkasse" fur BVD/MD since 1973. The article shows the cyclic procedure and regional differences as well as the participation of vaccinations and embryo transfer at the frequent occurence of persistent viraemic animals in single herds. According to the authors' opinion the struggle against BVD/MD must have two aims 1. to search for and to cull out persistent viraemic animals 2. to prevent the arise of new persistent viraemic animals.
