Determining the impact of diet on net greenhouse gas emissions and developing equations relating nutrient composition of feed, manure and GHG emissions for beef cattle, swine and poultry.


  • determine information on baseline GHG emissions for beef, swine and poultry manure applied to soil
  • develop mathematical models that integrate feed nutrient profile, manure nutrient profile and GHG emissions for beef cattle, swine and poultry
  • assess mitigation options to reduce GHG emissions from manure applied to soil
