Humans started domesticating farm livestock over 10,000 years ago. For much of this time, livestock have been changed genetically by subjective means. In the past 50 years, the application of scientific methods to animal breeding has led to major improvements in the output, cost and quality of animal products in the last few decades. This book describes the principles of genetic improvement of farm livestock and the practical application of these principles to dairy cattle, beef cattle and sheep breeding. Originally published in 1998 by Farming Press.

Through successive editions, Management and Welfare of Farm Animals has gained international recognition as a classic introductory textbook for students of agriculture and veterinary science. Conceived by the Universities Federation for Animal Welfare (UFAW), the book has always sought to promote the humane treatment of livestock within the practical business context of modern farming. Now fully revised and updated, this fifth edition remains the most comprehensive and accessible guide available. Three animal groups appear here for the first time (game birds, South American camelids, and ostriches), and a chapter on horses has also been restored. Throughout, the book offers clear advice for the humane management of all major farmed species in the primary context of large-scale food production. However, this edition also takes full account of consumer demand (and legal requirements) for alternative farming methods and enhanced welfare standards, whether in conventional agriculture or the smallest of ‘hobby' farms. Brand new chapters reflect fresh understanding of welfare science, ethics, and the role of society in ensuring the best possible farm conditions. It remains an indispensable resource for students, and for all those seeking to promote animal welfare. Published as a part of the prestigious Wiley-Blackwell – UFAW Animal Welfare series. UFAW, founded 1926, is an internationally recognised, independent, scientific and educational animal welfare charity.

In Masterminding Nature, Margaret Derry examines the evolution of modern animal breeding from the invention of improved breeding methodologies in eighteenth-century England to the application of molecular genetics in the 1980s and 1990s. A clear and concise introduction to the science and practice of artificial selection, Derry’s book puts the history of breeding in its scientific, commercial, and social context. Masterminding Nature explains why animal breeders continued to use eighteenth-century techniques well into the twentieth century, why the chicken industry was the first to use genetics in its breeding programs, and why it was the dairy cattle industry that embraced quantitative genetics and artificial insemination in the 1970s, as well as answering many other questions. Following the story right up to the present, the book concludes with an insightful analysis of today’s complex relationships between biology, industry, and ethics.

A productive dairy industry is vital to providing safe, high-quality milk that fulfills the nutritional needs of people of all ages around the world. In order to achieve that goal, Campbell and Marshall present a timely, lucid, and comprehensive look at today’s dairy industry. Dairy Production and Processing offers not only a fundamental understanding of dairy animals, dairy products, and the production aspects of each, but also a wealth of applied information on the scope of the current milk and milk products industry. The application of basic sciences and technologies throughout the text will serve students well not only as they learn the first principles of dairy science, but also as a professional reference in their careers. Study questions can be found at the conclusion of each chapter, along with relevant and informative websites. An extensive glossary is provided to enable readers to expand their knowledge of selected terms. Topics found in this instructive and insightful text include: • an overview of the dairy industry, • dairy herd breeding and records, • the feeding and care of dairy cattle, sheep, goats, and water buffalo, • important principles of milking and milking facilities, • dairy farm management, • milk quality and safety, and • the production of milk and milk products.

Should We Aim For Genetic Improvement In Host Resistance Or Tolerance To Infectious Disease

Recent advances in quantitative genetic and genomic studies have shed light on the important role of genetic control strategies for reducing disease risk and severity in livestock populations. There are two alternative host defence strategies to infectious pathogens that could be enhanced by genetic selection: improvement of host resistance versus improvement of host tolerance to infectious pathogens. Resistance refers to mechanisms that restrict the reproduction rate of a pathogen within a host, whilst tolerance mechanisms focus on minimising the damage that a pathogen inflicts on the host. Both strategies may have a similar impact on individual host fitness and performance, but can have contrasting effects on population performance and disease risk and severity. For example, improving host resistance may result in successful eradication of a disease from a livestock population, whereas disease eradication may be difficult if hosts are tolerant as these can harbour the pathogen without showing obvious or severe symptoms. On the other hand, it has been argued that increasing host resistance would fuel the arms race between host and pathogen and stimulate pathogen evolution towards higher virulence. Increasing tolerance, in contrast, imposes no or little selection pressure on the pathogen. Further, whereas disease resistance mechanisms may be specific to a particular pathogen (e.g. development of specific antibodies), tolerance mechanisms that repair damaged tissues are associated with the host rather than the pathogen, and are thus more likely to be generic to a range of pathogens. Hence, improving tolerance may be beneficial if individuals are exposed to a variety of pathogens or pathogen strains, and disease eradication has proven difficult. In contrast to evolutionary biology and plant breeding, animal breeding has only recently started to seriously consider a distinction between disease resistance and tolerance and their consequences. However, a deeper understanding of the underlying mechanisms and implications of improving either or both of the host defence mechanisms on future disease risk and severity is urgently needed by animal scientists, veterinarians and breeders to make informed decisions that help to maintain healthy livestock populations and guarantee food security. The topic ‘genetic improvement of disease resistance v tolerance’ would lend itself to research papers covering a variety of aspects that need to be considered, such as ‘how to obtain genetic parameter estimates and genomic breeding values related to disease resistance / tolerance’, ‘evidence for host genetic influence of resistance or tolerance’, ‘genetic, genomic and immunological understanding of resistance / tolerance mechanisms’, ‘epidemiological consequences of improving disease resistance / tolerance’. I believe that this research topic is both timely and relevant, and that sufficient knowledge is available across disciplines for composing valuable research / review articles that stimulate interest to a wide range of readers of Frontiers, and thus promote the growth of this journal.
