The objective of this study was to evaluate the supply of supplement of protein and supplement mineral in the rearing of crossbred steers Holstein x Zebu ½ maintained on Brachiaria brizantha. Marandu, in the rainy season and its implications on intake, nutrient digestibility and animal performance. Were used 22 steers averaging seven months of age and mean initial body weight of 164.09 ± 12.13 kg, distributed in a completely randomized design with two types of supplement and eleven repetitions per supplementation. The intake of dry matter (DM) total and of the nutrients had higher averages for animals receiving supplement of protein/energy. The use of supplement of protein/energy has improved digestibility of the nutrients of, except for the digestibility of neutral detergent fiber corrected for ash and protein (NDFap). The animals that received supplement of protein/energy presented better performance when compared to those receiving supplementation mineral. The use of supplement of protein/energy in the rainy season provides major input of nutrients, improves digestibility of nutrients and performance of crossbred steers reared in Brachiaria brizantha.
