Feeding Value of Ethanol Production By-Products

摘要

Efficient utilization of by-products is vital to the economic viability of ethanol production. Currently, returns from marketing of by-products can offset as much as 50 percent of the initial cost of conventional feedstocks used in ethanol production (Black et al., 1981). As ethanol production increases in the United States, the additional quantity of by-products must be integrated in animal feeding systems if this relationship is to be maintained.
