A new design for an intensive hog finishing operation is presented. The "maze deconfinement" system consists of 4-walled concrete pens arranged in a T-maze within a confinement building designed to utilize solar energy. In addition to low cost and efficient energy use, the system has the following advantages: higher feed conversion rate; less fighting among and injuries to hogs; some freedom for hogs to exercise and explore; decreased labor. The system has been used on the author's farm since the end of 1976.
