Effectiveness of Various Types of Shade on the Growth of Swine in a Normal Summer Environment¹

Purdue University Agricultural Experiment Station and Engineering Experiment Station, Lafayette, Indiana

Abstract

A total of 17 shade treatments involving 182 growing pigs were studied during the period of June 27 to September 12 in 1955 and 1956. The measure of shade effectiveness was the growth rate of pigs utilizing each type of shade. Comparisons were made of five basic roof materials: straw, plywood, corrugated steel and aluminum and laminated polyethylene plastic. There were no differences between materials and no measurable effects of roof color, including white, red and black upper surfaces, and combinations of painted upper and lower surfaces, on rate of gain of swine.

² Appreciation is expressed to Dr. S. K. Suddarth for assistance in the design of some of the shades.
