On an icy cold day at the Sustainable Pork Farm east of Texas Tech University, research assistant Anna Johnson, of Texas Tech, secures a video camera on top of a farrowing hut to monitor the behavior of the sow and piglets inside. The huts are part of a sustainable production system developed by university animal scientist John McGlone. In this system the animals roam freely and are not treated with antibiotics, yet they are healthier than those raised in conventional indoor systems.
