Abstract
In recent years pig production has been intensified in most European countries. This has resulted in a surplus of manure, exceeding the nutrient needs of the plants. In The Netherlands different laws have been introduced since 1984 to reduce these environmental problems. In this paper the development of pig production in The Netherlands, the environmental pollution by pigs and the policies to limit it are described. In addition, the approach in The Netherlands to reducing phosphorus and nitrogen excretion and ammonia emissions by means of nutrition is discussed. Finally, the potential and means for reducing the environmental problems in practical pig farming in the future by feeding and management measures are described.
