Our commitment to the economy

Since 2010, we have been partners and sponsors of the Centre for Sustainable Corporate Management (ZNU) at the University of Witten / Herdecke, NRW.

Another special feature is our Guarantee of Origin!


The WIESENHOF Guarantee of Origin: so that you know where your poultry comes from

More precisely, it comes from around 1,000 farmers who raise poultry in controlled free-range conditions. This ensures that the products always have a regional origin. The WIESENHOF Guarantee of Origin ensures the complete traceability of the products. For example, every pack of chicken gives details of the farmer or producer group who reared the animal.

At WIESENHOF, every stage of production takes place in Germany – from parent stock farming to hatcheries, rearing, slaughtering and processing right through to our own animal feed mills. The Group’s own independent controls guarantee the highest levels of safety and quality, which is documented by certifications from organisations including ISO, ifta and QS.


Sustainable operations from the very beginning

In the long tradition of our family business, responsible operations and sustainable business management have always been guiding principles for the company.

As early as 2009, WIESENHOF set up a centralised Sustainability Council comprising management-level members from different areas of the business in order to specifically promote and shape the learning process for the sustainable development of the company.

Since 2010, WIESENHOF has been a partner and sponsor of the Centre for Sustainable Corporate Management (ZNU) at the University of Witten/Herdecke in NRW. The Centre has developed the ZNU Sustainable Management standard, which serves to systematise the sustainability activities of the company and is intended to support companies in their sustainable development.

A total of 34 sustainability audits have been successfully carried out since 2013 throughout the PHW Group.


At present, six of our business units have been successfully certified according to the ZNU standard:

  • Märkische Geflügelhof-Spezialitäten GmbH
  • Anhaltinische Geflügelspezialitäten GmbH
  • Donautal Geflügelspezialitäten ZN der LOHMANN & Co. AKTIENGESELLSCHAFT
  • WIESENHOF Geflügelwurst GmbH & Co. KG
  • Oldenburger Geflügelspezialitäten GmbH & Co. KG#
  • Geestland Putenspezialitäten GmbH & Co. KG
