Destillers dried grains with soluble (DDGS) is a by-product when producing ethanol. DDGS from wheat has a high crude protein content and a good amino acid profile, which makes it an interesting feed ingredient for poultry. The disadvantage of feeding DDGS from wheat to poultry is that it also contains a high fiber content that chickens don’t have the ability to break down. Lantmännen Agroetanol has developed a new protein feedstuff from DDGS by extracting wheat protein from DDGS, the product name is Agroprotein SD. Unlike DDGS Agroprotein contains a smaller proportion of insoluble fiber but still has a good amino acid profile, making the product in theory better suited to poultry than DDGS. The present project aims to examine how Lantmännen...
