Soluble Non-Starch Polysaccharides Decrease Nutrient Digestibility and Ammonia Emission While Increasing Manure Odour

The use of soluble non-starch polysaccharide (NSP; guar gum) reduced ammonia emission in aged manure but decreased nutrient digestibility and increased odour emissions, thus limiting its environmental benefits. These are the conclusions from Eric van Heugten in an article published in the July 2009 issue of Swine News from North Carolina State University.
