Multiple farrowing schedules and systems adopted by many swine producers to “stretch” the season have increased the need for improved environmental control in the farrowing house. Maintaining temperatures near the best performance range of both sows and baby pigs has proven highly profitable. Desirable temperatures for sows and baby pigs differ greatly with the sow performing best at approximately 60 degrees (F.) while newborn pigs are most comfortable and healthy at 85-90 degrees (F.). Sow and pigs will produce best if these environmental temperatures are maintained for both summer and winter operation. Suggestions and floor plans for winter heating and summer cooling are included in this publication.
