Inclusion of dry distillers bran plus solubles (DDBS) in diets high in starch (corn) or pectin (citrus pulp) for finishing beef cattle in feedlot


The planned study aims to compare the performance of finishing beef cattle feed diets with different levels (0, 15, 30 and 45% on dry matter basis) of inclusion of dry distillers bran solubles and two different energy sources: starch/corn or pectin/citrus pulp. Three hundred and sixty eight Nellore bulls will be allocated in 60 experimental pens for 120 days. The following variables will be evaluated: dry matter intake, average daily gain, feed efficiency and carcass characteristics. The experiment will be carried out in a randomized block design with a 4 x 2 factorial arrangement. Data will be analyzed by PROC MIXED of SAS 9.4. All assumptions of the analysis of variance will be respected. Significance will be declared at P d 0.05. (AU)
