Research in animal nutrition


The research activities refer to food producing animals and companion animals likewise. The following shows the main emphasis of experimental studies concerning feed and feeding over the past few years.



Feed science

  • characterization of the phosphorus in feed with laboratory tests on solubility of phosphorus
  • investigations on sulfur and sulfate contents in roughages and concentrates for ruminants
  • influence of slaughter by-products on the consistency of feces in dogs
  • poisonous plants as feed contaminants(e.g. myopathy in horses)


Energy and nutrient requirements

  • interaction between digestibility of bulk and trace elements
  • S containing amino acids and foot pad health in poultry production
  • mineral and protein requirements during laying period in ornamental birds
  • effect of grinding technology and grinding intensity on digestibility, performance, gastric health and resident intestinal flora


Animal health and animal welfare

  • dietary measures/feeding concepts to prevent MMA-syndrome in sows (periparturient disorder)
  • relation between grinding intensity of feed and incidence of gastric ulceration in pigs
  • relation between protein source in the diet and infections with clostridia
  • impact of feeding/diet composition on litter quality and food pad health in broilers
  • dental health of small rodents affected by physical form of diets
  • interaction between infections of the GIT, nutrient utilization and performance of growing pigs (model: Lawsonia intracellularis)
  • interaction between grinding intensity and infections of the GIT in growing pigs (model: Salmonella Derby, E. coli)
  • whole-plant corn silage (wet-ground) as fiber source for pigs


Food safety / consumer protection

  • impact of diet’s physical form and of feed additives on prevalence of Salmonella in pigs and pig herds
  • feed contamination with dioxin/dl PCB and resulting pass over into milk or carcasses of cattle
  •  influence of genetics and dietary concepts on spreading of an infection with Campylobacter jejuni in chicken


Dietetics in human medicine

  • improving dietary measures/substitution of enzymes in exocrine pancreatic insufficiency (model: pancreatic duct ligated minipig)



Teaching duties / practical courses

Lectures and tutorials in animal nutrition (composition of feedstuffs, nutrition value, feed hygiene), feed additives, feed legislation, energy and nutrient requirements, recommendations on feeding different animals (horses, ruminants, pigs, poultry, dogs, cats, ornamental birds and small rodents), and feeds/feedings related influences on animals’ health as well as the dietetics/feeds for specific nutritional purposes.

Training of postgraduates to achieve the status of diplomates in animal nutrition (European College of Veterinary and Comparative Nutrition)



Services at the institute

Nutritional consultation for food producing and companion animals, feeding experiments, calculation and references for feed rations, feed related analytical service (feed, water, blood, body tissues) to enlighten incorrect feeding or to clear up warranty claims that seem to have nutritive causes
