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
High protein distillers dried grains (HP-DDG) were tested in combination with fermented soybean meal (FSBM) or soy protein concentrate (SPC), with and without an essential amino acid complex, to assess utility of these plant protein alternatives in Yellow Perch Perca flavescens diets in a 63-d feeding trial. Four experimental diets were formulated to contain equal amounts of HP-DDG and FSBM or SPC, each with and without essential amino acids and compared to a fish meal/HP-DDG reference diet. Fish that received diets containing SPC displayed the greatest weight gain, feed conversion, and apparent protein digestibility. Weight gain was significantly reduced and feed conversion significantly increased in the diet containing FSBM without essential amino acids. No mortalities or health assessment differences were observed during the trial and all treatment fish readily accepted the experimental diets.
