Hull-less barley is used as a source of energy and amino acids in swine rations in Western Canada but is characterized poorly in terms of DE content. Our objective was to determine the DE content of cleaned hull-less barley in relation to barley, wheat, and triticale. Chemical characteristics were analyzed to enable subsequent calculation of prediction equations. The DE content of cleaned hull-less barley was equal to that of wheat. We were able to predict the DE content of hull-less barley accurately by using starch, neutral-detergent insoluble nitrogen (NDIN) and neutral-detergent fibre (NDF) analyses.
