In the current energy scenario the management of electricity use is an indispensable support tool for the sustainable growth. In Brazil, the feed for swine and poultry are formulated, basically, with corn and bran of soy that usually need to be processed so that the feed has a specific size. This paper presents the management of the electricity use, by matching the use of motive force of animal feed factory at the Federal University of Viçosa. The evaluations of the motors' load and performance have been made at full load condition. For matching the use of motive force, substitutions of the electric motors by adequate motors of high performance and/or by changing the number of hours of annual operation were considered. The methodology adopted presented a potential economy with energy of 22.60%, R$ 1,728.28 in October, 2002, if the number of hours of annual operation increases, the adaptation of motive force with the use of motors of high performance, as well as sizing properly the mechanical demands of the factory, especially the mill were adopted.
