Odor Emissions and Chemical Analysis of Odorous Compounds from Animal Buildings


Why Study Odor Emissions from Animal Housing?

  • To determine odor emission characteristics by using common protocols and standardized olfactometry, from four mechanically-ventilated National Air Emissions Monitoring Study (NAEMS) sites, two dairy and two swine.
  • To develop a comprehensive chemical library that delineates the most significant odorants, and correlate this library with olfactometry results.
  • To disseminate information to stakeholders including producers, agencies, regulators, researchers, local government officials, consultants, and neighbors of animal operations.

Ethanol Co-Products Impact on Manure Nutrient Management Webcast

The rapidly expanding ethanol industry is producing increasing amounts of corn co-products that will be used in livestock and poultry diets. Inclusion of distillers grains and corn gluten feed in diets alter excretion of nitrogen and phosphorous in manure and therefore impacts nutrient planning. This webcast will explain how feeding ethanol co-products may impact manure nutrient management. The speakers are Joel DeRouchey, Kansas State University who will discuss the impacts for swine and poultry operations. Considerations for beef and dairy …
