The present invention relates to a method for the production of non-ruminant animal feed from plants and/or plant parts of the family of Poaceae, the method comprises the steps of harvesting plants and/or plant parts; extracting protein and fructan from said plants and/or plant parts: separating protein for feeding non-ruminant animals; and separating fructan for feeding non-ruminant animals, wherein the fructan stimulates bacterial growth and protein production in the large intestine of said non-ruminant animals and reduces the concentration of amino acid catabolites in the large intestine.
