By taking an entirely practical approach, this textbook aims to help those working with animals to apply methods for improving welfare, bridging the gap between scientific research and practical application. This book provides a guide to practical evaluation and auditing of welfare problems for farmed animals, emphasizing the importance of measuring conditions that compromise welfare such as lameness, or the use of electric goads. This second edition is fully updated with new literature, new, up to date coverage of pain management, and the addition of a new chapter on animal welfare in organic farming systems.
