Content:
Advances in Pig Welfare analyses current topical issues in the key areas of pig welfare assessment and improvement. With coverage of both recent developments and reviews of historical welfare issues, the volume provides a comprehensive survey of the field. The book is divided into two sections. Part I opens with an overview of main welfare challenges in commercial pig production systems and then reviews pig welfare hot spots from birth to slaughter. Part II highlights emerging topics in pig welfare, such as pain and health assessment, early socialisation and environmental enrichment, pig-human interactions, breeding for welfare, positive pig welfare and pigs as laboratory animals. This book is an essential part of the wider ranging series Advances in Farm Animal Welfare, with coverage of cattle, sheep, pigs and poultry. With its expert editor and international team of contributors, Advances in Pig Welfare is a key reference tool for welfare research scientists and students, veterinarians involved in welfare assessment, and indeed anyone with a professional interest in the welfare of pigs.
