Results
  • Use of clay minerals (bentonite) for pig feeding as well as algae materials as trinking water additive and for feed additive for fattening of broilers and ducks to reduce the odour and ammonia emission.
  • Investigation of pig houses with compost and deep litter system and natural ventilation
  • Investigation of alternative coverings of slurry containers
  • Treatment of liquid and solid manure with additives
  • Investigation of litter materials for poultry
  • Guidelines for minimum distance between livestock buildings and living areas (poultry, pigs, cattle)
