The U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture awarded a $617,065 Project Grant to the University of Wisconsin System under the Agriculture and Food Research Initiative (CFDA 10.310) program. The grant funds the development and field testing of a novel Positive Pressure Precision Ventilation (PPPV) system designed to cool dairy cow barns more efficiently and with lower greenhouse gas emissions than traditional ventilation approaches. The proposed research involves creating a full-scale computer model to refine the PPPV system design, followed by field testing to compare its performance to conventional ventilation systems. Key outcomes to be measured include animal health indicators, air pollutant levels, and operational costs. This research aims to identify cost-effective solutions for mitigating the impact of heat stress on high-producing dairy cattle in warming climates.
