Received: 22 July 2011 / Accepted: 9 August 2011 / Published: 25 August 2011 Abstract: Correlations between environmental parameters (thermal range and noxious gas levels) and the status (productivity, physiological, and behavioral) of growing pigs were examined for the benefit of pig welfare and precision farming. The livestock experiment was conducted at a Seoul National University station in South Korea. Many variations were applied an
