With a broad product range of tests, the DLG provides clear information on tested equipment and machinery. These tests form the foundation for impartial information for practitioners. The measurements are based on international standards and norms as well as tests developed in-house, building on practical requirements.

The DLG Test Center is accredited and notified nationally and internationally. Based in Gross-Umstadt, it develops state-of-the-art measuring techniques and efficient test facilities.

The DLG tests compound feeds, ensiling agents, cleaning agents, disinfectants, udder hygiene agents and animal housing disinfectants and lime fertilisers. DLG quality labels are issued to products that have passed stringent tests on the basis of the high DLG standards. The quality specifications are oriented to the requirements drawn from practice and are in line with the latest scientific findings.
