Evaluating Air Quality in Animal Housing

Air quality in animal feeding operations (AFOs) is relevant not only for human health but also the health and productivity of the animals living in that environment. What are some of the main principles in measuring air quality? What are some of the instruments that can be used? The following materials were developed for college instructors to utilize in their classrooms when presenting about air quality measurement in animal agriculture.

Measuring Bioaerosols in Animal Agriculture

Bioaerosols are particles of biological origin that are suspended in the air. These particles can include viruses, bacteria, fungal spores, and pollen. Bioaerosols are commonplace in the air, but measuring them presents some challenges. The following materials were developed for college instructors to utilize in their classrooms when presenting about bioaerosols.

Animal Diet and Feed Management for Reducing Air Emissions

Air emissions from animal agriculture operations and manure storage include gases and particulate matter (dust). The amounts and types of gases can be affected by many different factors, including animal diet. Altering animal diets to reduce the levels of air emissions can be done by finding ways to more closely match animal needs with nutrients available in their diet.

The materials on this page were developed to assist educators and professors who include animal diet, feed management and air emissions topics in their classrooms or educational programs.

This archive includes embedded videos 10 to 14 minutes in length. Topics include: beef cattle, reducing nitrogen excretion, dairy cattle, and swine. Links are included to download the individual videos and PDF versions of the presentation slides.

Additional Information

You may also be interested in visiting the LPELC Feed Management section for short articles (use the printer-friendly link to create handouts), archived webinars, and a series of dairy fact sheets. Most of these resources are focused on nutrient management with less emphasis on air emissions.

Ammonia Emissions from Animal Agriculture: An Introduction

Air emissions from animal agriculture operations consist of many different gases as well as suspended particulates (dust or microbes). One of these gases, ammonia, is gaining greater attention for its role in odor, but also as a precursor of fine particulate matter (PM 2.5). PM 2.5 has implications in haze and visibility as well as human health. The materials on this page were developed to assist educators and professors who include an introduction to include ammonia emissions as a topic in their classrooms or programs.

Dust From Cattle Feedyards: A Case Study From Texas

When talking about air quality around animal agriculture, one of the most common neighbor complaints comes from dust (sometimes also called particulate matter).  Dust is given off from cattle feedyards as animals move around on the pen surface. Although this dust usually settled out of the air relatively close to the feedlot, it can lead to nuisance issues with neighbors or nearby roadways. What causes dust emissions and how can we manage cattle feedyards in ways that reduce dust?

Airborne Emissions in Animal Agriculture

Air emissions from animal agriculture operations and manure storage include gases and particulate matter (dust). Some of these are potentially hazardous (hydrogen sulfide and ammonia). Others are scrutinized because they are greenhouse gases (carbon dioxide, methane, nitrous oxide) and others because they are odorous. All in all, hundreds of gases can be emitted from manure and animal housing.

The materials on this page were developed to assist educators and professors who include an introduction to airborne emissions and their management as a topic in their classrooms or educational programs.
