Remarks: Резюме: This publication covers a wide array of co-products and is a timely contribution, as people's aspirations are rising, evident from the increasing demand for livestock products and an ever greater reliance on transport, coupled with the challenge of maintaining agricultural production when faced with global warming. We hope that the information here synthesized will be useful to policy-makers, researchers, the feed industry, science managers and NGOs, supporting them in making information- based decisions on issues such as food-feed-fuel competition. Hopefully it will help confront the emerging challenges of global warming, in addition to making efficient use as livestock feed of a wide range of currently available and future co-products from the biofuel industry.
