The performance, intake and digestibility were evaluated in Nellore beef calves supplemented with different energy sources in Brachiaria decumbens pasture were evaluated. The area was divided into five 6.8 ha paddocks with an availability of dry matter and potentially digestible dry matter of 4.10 and 2.38 t/ha, respectively. Forty-five animals with 96.0 ± 11.0 kg initial weight and 101 ± 12 days of age were allotted to a completely randomized experimental design, as a 5 × 2 factorial (five supplements […]
