New legislation on animal welfare standards has created the need for welfare programmes to be implemented on farms, during transportation, and in slaughter plants. While there is a wealth of information on animal behaviour, ethics and factors effecting welfare, there is little to guide veterinarians and managers in evaluating animal welfare and improving it. This textbook aims to help those working with animals to apply practical methods for improving welfare, bridging the gap between scientific research and practical application. Drawing on the editor's extensive experience in teaching and auditing, and contributions from international experts, this book provides a guide to practical evaluation and auditing of welfare problems, emphasizing the importance of measuring conditions that compromise welfare.It will be an essential text for veterinarians and veterinary students and welfare auditing or welfare officer training, and broader animal welfare topics, helping students to apply their knowledge in the field.
