Abstract

Fractionation processes are being explored to supply higher protein distillers grains for premium markets. Resulting distillers grains after a fraction is isolated will still be marketed as a cattle feed so knowing the impact on performance is important. This study evaluated feeding wet or dry conventional distillers grains with wet and dry fractionated distillers (fiber plus syrup) fed at 0, 20, or 40% of diet DM. When compared to the corn control, intake and gain increased for each of the four distillers types were fed, but feed conversion was poorer (i.e., increased) for dry distillers grains and dry fiber plus syrup whereas feed conversion was equal across 0, 20, 40% inclusion for wet distillers grains and wet fiber plus syrup. Fractionation process did impact feed conversion by decreasing 3% when fed at 20 or 40% compared to conventional distillers grains plus solubles and as expected, fry byproducts perform poorer than we byproducts.
