Research output: Book/ReportReportProfessional


An experiment with 273 entire males was conducted on an organic pig farm. Half of these males received a herbal extract in the drinking water to reduce mounting behaviour and boar taint. The herbal extract did not affect sexual behaviour and boar taint. Only two carcasses (0,7%) had a typical boar taint. However a complete change towards non castration for organic pigs is not yet applicable partly because of international trade difficulties. A follow up study will be prepared
