Abstract

Two experiments, calves fed November to May (WINTER) and yearlings fed May to September (SUMMER), were conducted to evaluate effects of replacing dry-rolled corn with 30% corn bran or applying sawdust to the pen surface on feedlot nitrogen balance. Bran increased feed conversion during both experiments but reduced nitrogen losses in the WINTER. Sawdust application to the feedlot pen surface reduced nitrogen losses during the WINTER. Bran and sawdust treatments increased nitrogen recovered in manure during the WINTER. Adding OM to the pen surface did not impact nitrogen losses during the SUMMER.
