Utilization of <strong>feed</strong> <strong>co</strong>-<strong>products</strong> from wet or dry milling for beef cattle 97to g<strong>as</strong>oline. The GHG emissions of ethanol are dependenton whether wet, modified or dried DGS are produced <strong>and</strong>what animal cl<strong>as</strong>ses are fed.Maize milling <strong>co</strong>-<strong>products</strong> are excellent supplementsfor cattle on high-forage diets because they <strong>co</strong>ntain bothprotein <strong>and</strong> P, which are typically lacking in forage diets.In addition, the lack of starch in these <strong>products</strong> reducesthe negative <strong>as</strong>sociative effects of starch digestion on fibredigestion. Both ADG <strong>and</strong> final BW incre<strong>as</strong>e quadraticallywith incre<strong>as</strong>ed levels of DDGS supplementation, while forageintake decre<strong>as</strong>es quadratically.Co-product <strong>feed</strong>s from the ethanol industry are a great<strong>as</strong>set to the cattle <strong>feed</strong>ing industry. Continued researchshould explore interactions between different types of<strong>feed</strong>s <strong>and</strong> identify ideal <strong>feed</strong>ing situations in order to maximizeperformance.BIBLIOGRAPHYAl-Suwaiegh, S., Fanning, K.C., Grant, R.J., Milton, C.T. &Klopfenstein, T.J. 2002.
