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

Moisture Production rate (MP) from animals and their housing components provide fundamental data for the engineering design of a building environmental control system. MP of a commercial laying hen house with manure belt and tunnel ventilation was measured for a one-year period. The MP values included both latent heat loss of the birds and evaporation of moisture from the feces on manure belt. During the one-year measurement period, MP varied from 1.57 to 11.74 g H2O h -1 kg -1 with housing temperature ranging from 18 to 32 o C. Regression equations were established to predict MP of the commercial layer house over common ranges of outside temperature (-17 to 29 o C), RH (30% to 98%), inside temperature (18-32 o C), age condition (20- 42 wk and 97-119 wk) and lighting condition (light or dark). Results from this study provide new data for updated standards to be used in design and operation of laying hen houses.
