Abstract

The aim of this study is to evaluate the performance of feedlot finished steers receiving grain oat and/or soybean hull in their diet. Thirty six Nellore crossbred with Charolais steers, that received diet with concentrate ratio of 50:50 in all diets independently of the treatment, with sorghum silage as forage and concentrate according to the proposed treatment: soybean hull, oat grain and a mixed concentrate with these ingredients (50% of each as energy concentrate), were used. The experimental design was randomized blocks, the data was subjected to analysis of variance and F test using PROC GLM and means were compared by Student's “t”, α = 0.05 probability test. Significant difference was not observed between the treatments for daily gain in live weight of the animals tested. The dry matter intake was not altered by neutral detergent fiber content in this study. Both soybean hulls as the oat grain, had similar performance in feedlot finished steers.

Key words: Avena sativa, consumption, feed conversion, weight gain.
