Abstract: Systems and methods are provided which produce an improved distillers, brewers or fermenters grain by-products, including solubles, by determining nutrients and nutrient amounts to be added to a by-product to achieve targeted nutritional values, including bypass protein and amino acid levels, of the nutritionally enhanced grain byproduct after processing. One or more crude protein and/or amino acid content nutrient sources are added to the byproduct to create a nutritionally enhanced by-product mixture. The temperature and/or moisture content of the nutritionally enhanced by-product mixture is adjusted based on an empirically derived relationship that relates RUP as a percent of crude protein to an end product temperature in a predictable and repeatable manner to produce the improved distillers, brewers or fermenters grain byproduct. The products, having enhanced nutrient values of which are predictably ascertained, are made by the disclosed systems and methods.

Abstract: The invention is to products for enhancing the nutrient value of distillers, brewers or fermenters grain byproducts using an injector or mixer to add predetermined amounts of nutrients to the grains. The byproduct nutrient obtained is heated, dried and/or extruded to increase the ruminant bypass protein of the nutrient product.
