Every year, millions of Peking ducks are slaughtered at the duck slaughterhouse in Ermelo, a slaughterhouse that is part of a headache file for the Gelderland municipality: odor nuisance, haggling over permits and ducks that suffer needlessly during the slaughter process. Animal welfare organizations also monitor duck farms. There too, the natural needs of ducks are not met. Traditionally, there have been duck farms mainly in Gelderland, partly along the Veluwe. What does the ammonia emission from the ducks mean for the province's nitrogen policy?
