The pollution of excessive emissions to the environment severely restricts the sustainable development of the breeding industry.Pollutants discharged in weaned piglets production have its characteristics.On one hand,the bioavailability of nitrogen and phosphorus is low,resulting from the immature digestion and absorption system.On the other hand,to promote growth and prevent disease like diarrhea,high copper,zinc and lots of antibiotics are used,making nitrogen,phosphorus,copper,zinc and antibiotics the key pollutant in the production.This paper reviews nutrition technologies reducing these pollutants to investigate the possibility.
