Co-product feeds : animal feeds from the food and drinks industries

Co-product feeds are produced in British food and drink factories. They have the same provenance as the principal products of these enterprises, being derived from the same carefully selected raw materials and subjected to the same rigorous safety checks. Each co-product feed, often erroneously labelled as “processing waste”, is described precisely, allowing the reader to distinguish between grains and supergrains, peeled potato and potato peel, steep liquor and spent wash. It describes, for example, how sugar beet fields are audited to ensure good farming practice, how cooking destroys the anti-nutritional factor in raw potatoes, and chopping reduces the risk of choking and how the extraction of sugar and starch leads to higher energy value feeds. Guidance on feeding is provided, with cautionary notes for the farmer and pointers to the factory, where improved practices can enhance feed quality and increase demand. This book will be of value, interest and benefit to farmers, nutritionists, legislators, students and others involved in the feed industry.
