Animal Performance on Brachiaria brizantha Alone or Supplemented with Concentrate or Protein Bank of Leucaena leucocephala

The experiment was carried out at the Instituto Zootecnia, Nova Odessa, SP, Brasil, from June/1998 to March/2000 (634 days), and the liveweight gains of Nelore steers was evaluated, per animal and per area, on Brachiaria brizantha alone (T₁), B. brizantha + Leucaena leucocephala (T₂), B. brizantha + supplemental feeding during the dry season (T₃) and B. brizantha + supplemental feeding during the dry and rainy season (T₄). The experimental design was a randomized block, with four replications each one composed by three paddocks rotationally grazed by Nelore steers. Mean weight gain per day and per hectare were 0.426 and 1.050, 0.459 and 1.150, 0.497 and 1.259, and 0.535 kg and 1.331 kg, respectively.
