Preparing a Finishing Barn

Publish Date: 04/17/2012

The right start involves a clean, dry and disinfected environment that is properly ventilated and heated and/or cooled. The environment must also provide adequate access to feed and water, have sufficient space, and be free of objects that can cause injury. The steps to preparing a barn for a new group of pigs should be done systematically so as to avoid holes in biosecurity and preparedness.
