Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.
History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract
Particulate matter (PM) in animal feeding operations is a concern for the occupants and the surrounding community. Baseline measurements of the concentration and emission rate of PM are the first step toward assessing the environmental impact of animal feeding operation and evaluating the effectiveness of dust control strategies. This study presents the results of the PM measurement at a high-rise layer house in central Iowa. The average PM10 emission rate over the 9- month measurement period was 21.6 (±10 S.D.) mg/bird/day. Comparing with the emission rates reported literature, the mean and range of PM10 emission from high-rise layer hen barns using cage systems were 33.5 and 19-48 mg/bird/day. The average PM2.5 emission rate over the measurement period was 2 (± 1.5 S.D.) mg/bird/day, which is less than literature values of 3.52-14.2 mg/bird/day.
