This book provides both evidence-based scientific studies and practical guidance to enhance the welfare of cattle, pigs, sheep and poultry at slaughter. Temple Grandin and Michael Cockram have brought together a range of international experts to prepare chapters on philosophical and ethical views on the slaughter of farmed animals. These include welfare issues and their assessment, the condition of animals on arrival and their management during lairage, animal handling, methods of humane slaughter and assessment of unconsciousness. The book boldly tackles controversial issues around the compromises necessary when balancing animal welfare concerns with commercial realities, as well as religious slaughter. Chapters cover methods of stunning, pre-slaughter handling, equipment design, monitoring welfare with abattoir data and auditing methods. It is an important publication for those involved in implementing improvements in the humane slaughter of farmed animals and is recommended for veterinarians, students, abattoir managers and government regulators.

Livestock Epigenetics reviews advances in the understanding of the molecular basis of epigenetic mechanisms in gene expression in livestock species. Epigenetics impact many economically important traits from growth and development to more efficient reproduction and breeding strategies. The book opens with a broad introductory chapter that discusses the importance of an understanding of epigenetics to efficient and sustainable livestock production. In subsequent chapters the role of epigenetics in specific aspects of animal production are reviewed. The final chapter provides researchers with a valuable basis for the use of comparative epigenetics research to allow research to apply advances across organisms. Livestock Epigenetics provides detailed information on this rapidly expanding field of research with contributions from a global team of experts.

This comprehensive book integrates new technology and concepts that have been developed in recent years to manage dairy farms in a profitable manner. The approach to the production of livestock and quality milk is multidisciplinary, involving nutrition, reproduction, clinical medicine, genetics, pathology, epidemiology, human resource management and economics. The book is structured by the production cycle of the dairy cow covering critical points in cow management. Written and edited by highly respected experts, this book provides a thoroughly modern and up-to-date resource for all those involved in the dairy industry.

Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

A guide to the field of animal health economics and its underlying methodology. Supplied with this book is a diskette, containing practical exercises (in computer spreedsheets) on the various methods and techniques in animal health economics, including production function analysis.
