The proper use of natural resources in the design of broiler facilities reduces operating costs of the farm and optimizes production conditions. The natural shade surrounding the facilities may be an alternative for improving the internal conditions of the animal housing. The objective of this study was to evaluate the efficiency of shading in broiler sheds oriented east-west. To do so, we compared the productivity index (PI) of 29 broiler sheds, each with the same management, same density and building characteristics while the shades were divided into different sides of the barn, i.e., the northern side only, the southern side only, both south and north sides and no shade. Five flocks were produced annually. It was found that the flocks grown in the milder periods of the year, between autumn and spring, with shading on the south sides of the barns showed superior PI. As for the summer period, barns without shading showed higher PI.
