About us
Since its foundation in 1996 as Ahrens & Osterhoff GmbH in Hemer-Landhausen, AHRHOFF has been supplying completely new concepts for animal nutrition and bioenergy production combined with a comprehensive range of consulting services for farmers.
For our clients we offer business consulting as well as seminars with practical and scientific based international speakers.
Our team from Marketing & Sales, Administration & Production and the Scientific Department combines a wide range of perspectives and expertise.
Philosophy
We offer unique and high quality supplements combined with comprehensive consultancy through our highly educated AHRHOFF nutritionists.
The company not only supplies clients in Germany, but also established close relationships with clients in the Baltic states, Hungary, Luxembourg and South Africa.
The basis of our consultancy is a precise survey of the existing conditions and operational possibilities on the specific farm. As part of the analysis of the current situation, we work closely with the farmer to develop a target setting. These targets remain within the focus while monitoring and optimizing the production processes. Our top priority is to increase the efficiency of the farm while maintaining a healthy livestock population.
