Abstract

Three dietary corn silage levels (15, 30, and 45% of diet DM) were evaluated in corn finishing diets fed to calves through the winter/spring and yearlings during the summer to determine effects on performance and nitrogen mass balance in feedlot. Yearling gains decreased quadratically with increasing corn silage; however, N and OM removed in manure was greatest for the 30% silage treatment. Calf gains decreased linearly as silage increased; however, N and OM removed in manure was greatest for the 45% silage treatment. Increasing dietary corn silage resulted in decreased gains but did influence manure N with no effect on N volatilization.
