Abstract 

The objective of this study was to evaluate the performance of calves fed supplemented energy or not maintained in oat (Avena strigosa Schreb) managed under two forage allowances. Sixteen Marchangus (1/4 Marchigiana 1/4 Angus 1/2 Nelore) animals were used at eight months old and average initial weight of 200 kg. The experimental design utilized was completely randomized in a 2*2 factorial (two forage allowances * two feeding - with and without supplementation of corn). There was no significant interaction between supply and supplementation for the variables. The real forage allowance was close to the expected from 6 to 10% (5.95 and 9.07%, respectively). The offer of 6% shows higher percentage of leaf (57.0 versus 30.4%), lower percentage of stem (43.0 versus 69.6%) and, consequently, higher leaf/stem ratio (1.45 versus 0.45), resulting in better forage (PB=20.0 versus 13.6%), in lower offer. The accumulated rate was higher (P<.05) for forage allowance of 6% (34.2 kg of MS/ha/day) in relation to the offer of 10% (28,1 kg of MS/ha/day). Supplemented animals showed higher average dairy weight (.749 versus .549 kg/day).
