What Did We Do?

Modeling: The overall goal of the modeling effort was to enhance the National Pork Board swine carbon footprint calculator by integration of specific modules for: animal growth and feed ingredient impacts on manure characteristics.…

Why Develop Models for Pork Production and Environmental Footprint?

Change in complex systems can occur either systemically, for example by government policy or regulation, or by adoption of new practices by individuals followed by wider adoption where the new practice is effective.…

Feed Management and Phosphorus Excretion in Dairy Cows

What Is the Connection between Phosphorus and Water Quality?

Holstein Cow

“Phosphorus (P) is an essential element for plant and animal growth and its input has long been recognized as necessary to maintain profitable crop and animal production. Phosphorus inputs can also increase the biological productivity of surface waters by accelerating eutrophication.…

Research Summary: Turnip Response to Vermicompost

Research Purpose

Vermicomposting separated swine solids is a way to reduce odor and pathogens in a product that can be used off site as a nutrient source and soil amendment. The solid separation system removes a portion of the nutrient and organic loads from the liquid waste stream prior to entering the lagoon system while the vermicomposting process stabilizes the nutrients and organics that are diverted from the lagoon, making it easier to find off-farm uses for the product.…

Research Summary: Evaluation of a Synthetic Tube Dewatering System for Animal Waste Pollution Control

Research Purpose

The objective of this field study was to evaluate the performance of a Geotube® dewatering system under field conditions by quantifying the mass removal efficiency of solids, nutrients, and metals from well-mixed dairy-lagoon slurry dewatered by this system.


A Geotube dewatering system was set-up to treat the lagoon slurry mix from the primary lagoon of a 2000-head lactating cow open-lot dairy (Fig.…

Air Emission and Energy Usage Impacts of No Pit Fans in a Wean to Finish Deep Pit Pig Facility

What Is Being Measured?

The objectives of this research project are to monitor the indoor air quality of a deep-pit; wean-to-finish pig building over one pig-growth cycle (six months) by semi-continuously measuring concentrations of ammonia (NH3), hydrogen sulfide (H2S), carbon dioxide (CO2), methane (CH4), and volatile organic compounds (VOCs) and intermittently measuring particulate matter (PM10) and odor.…

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.
