Date Apr. 29, 1982.A method and apparatus prevents piglets from being suffocated under a sow by detecting when the sow stands up and establishing an unpleasant condition, specifically blowing air under the sow to discourage the piglets from moving under the sow. A pleasant condition can simultaneously be established at a location spaced from a pen confining the sow to further encourage the piglets to stay away from the underside of the standing sow.
