Description: Many of the existing sow farms in Canada face the challenge of remodeling current barns or designing new facilities to meet regulatory and societal demands to convert from stalls to group housing system. In the barn conversion process, most pig farmers focus mainly on remodeling the penning and floor layout to transform the barn to group housing, while the ventilation system is frequently neglected or overlooked. In this study, various configurations of the ventilation system of a newly-converted group sow housing facility were evaluated to determine the necessary changes to the ventilation system that must be done when converting sow barns from stalls to group housing system. Computer simulation was utilized to develop and evaluate different ventilation system design configurations, followed by actual in-barn evaluation of the selected ventilation design configuration to assess its impact on actual energy costs, indoor air quality, and sow productivity. Among all the design configurations tested, horizontal flow ventilation system was the most effective in removing heat from the animal occupied zone (AOZ) in the room during both summer and winter seasons. In-barn evaluation of this ventilation system design showed about 21% reduction in natural gas consumption during heating season and 14% reduction in electricity consumption relative to a similar room with unmodified ventilation system. Analysis of incremental costs from the in-barn implementation showed that energy savings from this modified ventilation system can offset the capital and operating costs for installing the system, with estimated payback period of about 2.2 years.
