The history of Science is replete with untold stories and this book is one of these accounts. The author shares a narrative of heredity, an active topic of inquiry long before Gregor Mendel - the father of genetics - planted his peas. One such interlude unfolded in Mendel's home city and involved the sheep breeder, Imre Festetics. He sought to improve wool and proposed important rules of heredity. Unfortunately, aspects of wool quality, now known to be polygenic, complicate interpretations of the work of Festetics and explain why it is neglected. The forebearers of Mendel never get the credit they deserve. Heredity Before Mendel resurrects Festetics, the grandfather of heredity. Key Features 1) Documents a vibrant community of scholars interested in heredity before Mendel 2) Highlights the work of Imre Festetics, the forgotten grandfather of genetics 3) Desribes political repression which stifled the nascent foundation of heredity research 4) Emphasizes the role sheep and wool played as the first model system of genetics 5) Challenges19th century taboos in Moravia leading to malicious rumors about the inbred royal House of Austria (Habsburgs).

For animal breeders coat color genetics is one of the fundamental elements of breeding, along with health and conformation. Breeders need to know about coat color for showing purposes and where the fibre is used in industry, for example sheep and alpaca wool. Breeding for coat color is complicated because many dominant and recessive traits interact to produce the base coat color. Alleles for these occur in pairs, so that the phenotype, or visual appearance, does not always reflect the underlying genotype. Practical Color Genetics for Livestock Breeders is a guide for breeders on the biology behind coat color in large animals directing breeders on how to implement breeding strategies to achieve desired results.

Before crude oil and the combustion engine, the industrialized world relied on a different kind of power - the power of the horse. Horses in Society is the story of horse production in the United States, Britain, and Canada at the height of the species' usefulness, the late nineteenth and early twentieth-century. Margaret E. Derry shows how horse breeding practices used during this period to heighten the value of the animals in the marketplace incorporated a intriguing cross section of influences, including Mendelism, eugenics, and Darwinism. Derry elucidates the increasingly complex horse world by looking at the international trade in army horses, the regulations put in place by different countries to enforce better horse breeding, and general aspects of the dynamics of the horse market. Because it is a story of how certain groups attempted to control the market for horses, by protecting their breeding activities or 'patenting' their work, Horses in Society provides valuable background information to the rapidly developing present-day problem of biological ownership. Derry's fascinating study is also a story of the evolution of animal medicine and humanitarian movements, and of international relations, particularly between Canada and the United States.

To meet growing demand, the FAO has estimated that world poultry production needs to grow by 2-3% per year to 2030. Much of the increase in output already achieved has been as a result of improvements in commercial breeds combined with rearing in more intensive production systems. However, more intensive systems have increased the risk of transmission of animal diseases and zoonoses. Consumer expectations of sensory and nutritional quality have never been higher. At the same time consumers are more concerned about the environmental impact of poultry production as well as animal welfare. Drawing on an international range of expertise, this book reviews research on poultry breeding and nutrition. The first part of the book reviews how advances in genetics have impacted developments in breeding. Part 2 discusses ways of optimising poultry nutrition to ensure quality and sustainability in poultry meat production. Chapters review the use of feedstuffs and ingredients such as amino acids, enzymes and probiotics as well as feed formulation and safety. Achieving sustainable production of poultry meat Volume 2: Breeding and nutrition will be a standard reference for poultry and food scientists in universities, government and other research centres and companies involved in poultry production. It is accompanied by two further volumes which review safety, quality and sustainability as well as poultry health and welfare.
