Impact of nutrition on nitrogen , phosphorus , Cu and Zn in pig manure , and on emissions of ammonia and odours

  title={Impact of nutrition on nitrogen , phosphorus , Cu and Zn in pig manure , and on emissions of ammonia and odours},
  author={J. Y. Dourmad and Catherine Jondreville},
In order to reduce N, P and trace elements in pig manure, research toward a better agreement between supply and requirement has been undertaken in recent years, and ways to improve the biological availability of these elements in feedstuffs have been investigated. Substantial reduction in N excreted by pigs can be achieved by phase feeding combined with a better adjustment of the dietary amino acid balance. Feeding pigs with low N diets also allows a reduction of ammonia emission and to some… CONTINUE READING
