This manual provides practical guidelines to assist farmers, producers and all stakeholders along the feed value chain to comply with the requirements of the Codex Alimentarius Code of Practice on Good Animal Feeding. It guides managers of feedmills, the feed industry as a whole, and on-farm feed mixers and producers. It will also be of value to national competent authorities, and can serve as a training manual and guide for setting up national feed associations. Animal feed plays a leading role in the global food industry, enabling the sustainable and safe production of food of animal origin throughout the world. Under a wide range of farming conditions, feed, be it produced in industrial feedmills or in more simple on-farm mixers, is the largest and most important component in growing animals for food, traction or transport, fibre and other products. The manual suggests that the application of the Code is an important step for the expansion of international trade of feed and products of animal origin. Both feed/food exporting and importing countries can benefit from a greater and safer trade of feed and products of animal origin.
