Understanding Animal Welfare, 2nd Edition is revised and expanded to incorporate new research and developments in animal welfare.  Updated with greater accessibility in mind, the reader is guided through animal welfare in its cultural and historical context, methods of study, and applications in practice and policy.  Drawing examples from farm, companion, laboratory and zoo animals, the text provides an up-to-date overview of research and its applications, while also tracing how concepts and methods have evolved over time.  Originally intended for scientists and professionals, Understanding Animal Welfare has also found a home in undergraduate classrooms. It is now the essential text for students, practitioners, veterinarians, and researchers in animal welfare and related fields.
