摘要：

An experiment was conducted at the Universidade Federal de Santa Maria, in Santa Maria, RS, Brazil, with the objective of evaluating the effects of three N levels (0, 150 and 300 kg/ha), in pearl millet (Pennisetum americanum (L.) Leeke) cv. Comum, on animal production. Beef steers were assayed through daily liveweigh gain, gain per hectare and animals.day/hectare. A continuous grazing system was used, with stocking rate adjustments to maintain a 10% grazing pressure that characterized a medium residue of 3,168 kg of DM/ha. The dependent variables showed a positive linear relationship with the N levels, denoting the high animal production potential of pearl millet.
