This trial was carried out in Luiziana, northwest of Paraná, from November 2000 to February 2001. Twenty-four animals with 325 kg of initial body weight and 13 months of age, from two different genetic groups, ½ Red Angus ½ Nellore (20) and ½ Marchigiana ½ Nellore (12) were used. Animal performance was evaluated, under grazing conditions on coastcross (Cynodon dactylon (L.) Pers) and four levels of soybean hulls: 0, 0.2, 0.4, and 0.6% of body weight. Pasture production and quality were also evaluated. The experimental area consisted of four paddocks of Coastcross, with 5.05 ha of total area. After 112 days of experimental period, all treatments showed high gains per animal (above 0.850 kg/day).
