Effective ventilation brings pig health benefits in chilling times

April 2005 During extremes of weather pig farmers tend to become more aware of the specific ventilation needs of the pigs in their care. In particular, as winter turns to spring and back to winter in the same day, respiratory stress can be a problem particularly when there is a vast daily fluctuation in ambient temperature. The change to all-in/all-out production imposes greater demands on the competence of the ventilation system because of the wider weight range between the entry and exit weights of pigs in the same building. When lightweight pigs first enter the building, ensuring that excessive air movement does not chill the pigs is important and this is often brought about by running the pig environment at the minimum ventilation rate or simply depending on air leakage to achieve it.
