Two experiments were conducted to measure the influence of trough space (170 mm, 350 mm and 700 mm/animal) and pen area (5,5 m2, 11 m2 and 22 m2/animal) on feedlot performance. There was no advantage in allowing more than 170 mm trough space or more than 5,5 m2 floor area per animal with the conditions and climate under which these trials were conducted.
