A new publication from Iowa State University (ISU) helps producers to select energy-efficient fans for hog barns.

“Energy-Efficient Fans for Swine Production” (PM 2089E) can be downloaded from the Extension Online Store, www.extension.iastate.edu/store/.

Inefficient fans can increase a farmer’s cost of production, says ISU Extension program coordinator Dana Petersen. The most obvious cost is wasted energy during operation of an inefficient fan. Other costs can occur from poor air quality due to underventilation or wasted heat due to overventilation. Inefficient or mismanaged fans can lower air quality and stress animals, making them more prone to disease and reducing growth and feed conversion.

The publication is part of a series of farm energy conservation and efficiency educational materials being developed through the Farm Energy Conservation and Efficiency educational initiative. The purpose is to help farmers improve efficient use of farm energy, explore alternatives to reduce farm energy demand and improve their overall profitability.

Iowa State University Extension received a grant from the Iowa Energy Center to carry out the initiative.
