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.
