Heat Exchangers in Swine Facilities

Publish Date: 04/04/2012

Ventilation air-to-air heat exchangers are used in swine housing facilities to reduce supplemental heating cost and to preheat incoming fresh air. There is potential for heat exchanger use in some swine barns, since as much as 90% of the total heat loss from an insulated swine nursery facility occurs through the minimum ventilation air exchange. Heat exchangers recover a portion of this loss, depending upon design and maintenance. In addition to reducing fuel use, heat exchangers preheat the incoming ventilation air thereby reducing the potential for drafts on piglets and reducing frosting problems when air enters directly from outside. Heat exchangers also improve air distribution, because warmed inlet air will not drop as rapidly as cold inlet air.

Swine Farrowing Units

Publish Date: 06/03/2006

A wide variety of choices is available in farrowing units—from the A-frame portable building on pasture to the environmentally-controlled central farrowing unit with slotted floors. Although good management and proper environment are the most important requirements for a successful farrowing operation, well-planned and properly constructed buildings and equipment make both easier.
