Technical Abstract: The biofuels industry has exhibited astonishing production advances in the past decade and, in its wake, has lead to a wide diversity of co-products available to the livestock industry. During times of historically high prices for grains, proteins, minerals, and fats, this has lead to a rapid increase in research activities evaluating the nutritional potential of these products. For example, from the biodiesel industry, research has recently been conducted on the availability of energy from crude glycerin for swine and poultry of various ages, and on the variability of energy from crude glycerin produced from biodiesel plants utilizing different initial feedstock. Likewise, from both the wet and dry corn milling industry there are numerous products produced that vary in CP, AA, P, S, GE, and "fiber" concentration. Data will be presented showing variations in the nutrient profiles of these co-products, how they might fit into feed formulations, limitations or concerns with product use, and variability of co-product quality.
