The risk of inefficient use and management of environmental control systems such as lights, ventilation and cooling systems on dairies is increased energy use and electricity costs, but also decreased milk production, said Erin Cortus, SDSU Extension Environmental Quality Engineer.

"This risk is amplified during periods of heat stress. There are numerous heat abatement methods and systems available for both naturally and mechanically-ventilated barns. Are they working to their full potential," Cortus said.

SDSU Extension and University of Minnesota Extension staff will discuss this topic during the Aug. 27, 2013 workshop on Evaluating Heat Stress and Energy Use on Dairies from 10 a.m. to 3 p.m. at the Hammink Dairy located at 200th Street and 469th Avenue, Bruce.

"This workshop will provide dairy producers with tools and techniques to evaluate their barn's environment and establish a baseline for their system," Cortus said.

Workshop details

The morning session will cover the costs of heat stress and how to reduce the impacts of heat stress with the ventilation and cooling system. The afternoon session will be an open-house format consisting of hands-on stations around the farm where presenters will share information on specific topics such as lighting, fan capacity and efficiency, airspeed through the pens, observing heat stress, energy audits and sprinklers and misting systems.

This workshop is a joint effort between SDSU Extension and University of Minnesota Extension, and is based upon work supported by USDA/NIFA under Award Number 2012-49200-20032.
