Air quality is becoming of increasing importance as we spend more time in our barns. Clean, fresh air also contributes greatly to the health of our pigs. The following 10 steps are intended to help you keep your mechanically ventilated barn an inviting place for you to work and for your pigs to grow.
1. Fresh air intakes servicing room air inlets.

Openings must be provided to allow air into a building. These can be a louvered hole in the gable end of a barn, a screened slot in one or both soffits or an opening into a hallway.
