The research activities at the professorship include feedstuff-related questions concerning the suitability, quality, and safety of feedstuffs and feed additives, as well as animal-experimental work to study the effects of feeding on the nutritional physiology and health of livestock. Scientific questions focus on implementing sustainable animal nutrition, i.e., animal feeding is aimed at economically producing safe and high-quality animal-origin foods while also considering aspects of animal health, welfare, resource efficiency, and environmental protection.

At the experimental station "Friedrich Harms" specially designed feeding rations are produced, which are subsequently tested in feeding trials to provide a comprehensive assessment of the nutrition-related impacts on digestive physiology, health, and performance of agricultural livestock. In addition, in vitro studies are conducted to simulate and evaluate nutritive effects on nutritional-physiological processes and animal health outside the organism.

The professorship of Animal Nutrition and Nutritional Physiology has laboratories equipped with the latest measurement and analytical technology for conducting analytical and experimental work. This enables the examination of feedstuffs for various constituents and physico-chemical properties as well as the preparation and analysis of sample material obtained from feeding trials.
