德语. As a recent development, the byproducts of ethanol, starch, sugar and beer, are partly dehydrated thus reducing the transport volume and inc reasing the nutrient concentration. The separated fluids have less tha n 2 % DM and can conduct to filter plants and can conduct sometimes af ter repeatedly separation. The remaining byproducts are named: wet sol id stillages: the separated hot stillages; pressed pulps: residues fro m cold extracted fresh plant material; pressed scraps and pressed brew ers grain: the pressed hot original byproducts. The DM-contents varied from 16 to 33 %, the crude ash contents were always low; the crude fi ber content was in average 18 % and varied little, the standard deviat ion was only 3 % absolute. Ordinarily, the crude protein content was l ow in pulps and scraps and high in stillages and brewers grain. Nitrog en-free extracts and digestibility were always high and the net energy lactation (NEL) was relatively high, too. Usually high stillages had a lower pH than the other byproducts. Residues from sugar and fodder b eets had even more sugar than byproducts of other plants
