When we look across the Canadian pork industry it becomes apparent that due to the age of most facilities a large percentage will need to be replaced or renovated over the next few years – as most buildings average between 20-30 years old. The majority of production units are completely enclosed utilizing a negative pressure ventilation system to maintain pig comfort. In order to reduce heating costs during winter months ventilation is generally turned down to a minimum ventilation rate. The combination of minimum ventilation and, in some areas high winds, causes exhaust air to recirculate within the facility leading to poor air quality. This in turn increases deterioration due to increased exposure to moisture and corrosive gases. This project set out to determine Canadian specific strategies for decreasing barn deterioration.
