Weaned pigs also used wheat millrun as an energy source. After partial removal of starch from wheat, fibre in wheatmillrun is concentrated compared with wheat grain (Zijlstra et al., 1999). Thus, the energy value of most grain by-productsis low (NRC, 2012). As the major energy-yielding component in wheat millrun was fibre, which was negatively related toenergy digestibility and DE value
