During spring 1966 the veterinary practitioners of the canton Waadt were confronted with the illegal import of bovine semen and cattle from France. The Société Vaudoise des Vétérinaires wrote an "open letter" to the former Federal Councillor Schaffner. This letter achieved a partially liberalization of the importation of bovine semen of foreign breeds.
