A project was initiated by the Agricultural Engineering Department at the South Dakota Agricultural Experiment Station to design a type of swine shade which would not require all the heavy timber under-framing of the current swine shade plans, and which would be actually "portable." The need for such swine shelters has been established; research results from other stations have shown that some shading device, either natural or artificial, is necessary to protect swine, especially the heavier ones, from the direct heat of the sun. Extensive work conducted at California shows the effects of different types of surfaces and shade materials on the radiant heat load beneath the shade. Another report, one from Purdue University on the effectiveness of various types of shade on the growth of swine in a normal summer environment, concluded that there were no differences between materials used and no measurable effects of roof color on rate of gain of swine. While these studies may not agree on the effectiveness of different types of shading materials, their findings support the need for some type of shade for swine to maintain or improve rate of gain.
