Substantial volumes of co-product feeds are produced in British food and drink factories. Although sometimes referred to erroneously as processing wastes, these feeds have the same provenance as the principal products of such enterprises, being derived from the same carefully selected raw materials and subjected to the same rigorous safety checks. In this book, over 80 feeds are described precisely in both words and figures, so that each one may be considered on its merits as a potential ration ingredient. A range of background information provides additional reassurance: how sugar beet fields are audited to ensure good farming practice; how potatoes are chopped and cooked to improve both their nutritional value and safety; how the extraction of sugar and starch from grain leaves feed materials that are richer sources of energy and protein. Guidance on feeding and storage is provided with cautionary notes for the farmer and pointers to the factory where improved practices can enhance feed quality. "Co-product Feeds" describes the entire chain by which food-quality raw materials are selected and then processed, so that the feeds that become available as co-products of that processing can be purchased and used with confidence.
