The practice of total confinement of beef cattle as an alternative to the open feedlot has generated a considerable volume of literature on the subject over the past decade. An appreciable portion of this, however, is of a subjective nature. Earlier reports, as noted for example by McFarlane (8) and Turnbull (12), often were limited to discussions of techniques and management relating to different systems of total confinement. In recent years, a more analytical approach to the subject has been apparent but comparisons based on animal performance between these alternative systems of housing and open feedlots are difficult to make. Maddexa suggests that this is due to the objectives of the projects and the background of the researchers involved. Furthermore, there are management, feeding, and climatic variables existing between countries and regions from which studies have been reported, and these differences require careful interpretation if valid comparisons are to be made.
