My husband and I have been through numerous production models in the swine industry. Our latest move from Minnesota to Tennessee essentially transitioned our swine operation from completely contained confinement buildings to outdoor free range. We gave up concrete, climate control and automatic feeding for mud, chasing pigs through timber and more mud. The new plan has definitely down-sized the herd from hundreds of sows to two and has seen cedar posts and wire panels replace farrowing crates and manure pits.
