Effects of Corn Distillers Dried Grains with Solubles and Dehydrated Alfalfa Meal on the Utilization of Urea Nitrogen in Beef Cattle1

G. W. Horn and W. M. Beeson

Purdue University, Lafayette, Indiana

Abstract

The addition of corn distillers dried grains with solubles (DDGS) or dehydrated alfalfa meal (DEHY) to high-urea diets significantly improved nitrogen retention in steers. Ruminal ammonia and blood urea levels were not affected by treatment in any of the experiments. A shift in the concentrations of individual or total rumen VFA's was not observed as a result of adding DDGS to the basal diet; whereas, the addition of DEHY to a basal diet significantly increased acetic acid (P<.01) and total VFA's (P<.05) in the rumen contents of steers. Plasma free amino acid concentrations were not affected by DDGS but were less when fed DEHY.
