Descripción:	Abstract: The objective of this work was to compare the average daily live weight gain (ADG) of Nellore steers, stocking rate (SR) and gain per area (GA) in pastures of three Panicum maximum cultivars. The experiment was conducted in Planaltina, Federal District, Brazil, during 248 days, divided into rainy (140 days) and dry (108 days) season. Treatments were cultivar Zuri, cultivar Tamani and cultivar Massai managed in rotationally stocked pastures under a 28-day grazing cycle (21-d of rest and 7-d of grazing) during the rainy season and a 56-day grazing cycle (42-d of rest and 14-d of grazing) during the dry season. Adjustments in stocking rate were performed considering the same herbage allowance between treatments. ADG (216 kg weaning steers) was 0.352, 0.391 and 0.254 kg/head for Zuri, Tamani and Massai pastures, respectively. ADG decreased in dry season but kept showing higher values for Zuri and Tamani. Differences in individual performance were associated with higher crude protein and digestibility of forage, especially for Tamani. SR values were higher for Massai and Zuri pastures for both seasons of the year, but the GA was similar between all treatments. Although Tamani provided low stocking rates, GA was partially compensated by high ADG values. Cultivar Zuri succeeded to combine high stocking rates with high individual animal performance.
